Re: [PHP] Unsetting a header

[Rafael]

Let me reiterate, I want this page to get cached, but not based on an 
Expires: header. Rather a Last-Modified header.


	Have you tried setting the value to FALSE, NULL, or something else? I 
recall having read something along those lines. I'll see if I can find 
it again, meanwhile you could experiment a little.

In fact you can access the filesystem with "signed" javascript scripts. 
 Which by "signing" you Javascript, you will be allowed to access the 
local file system.


But, again, it is all about the permissions.

	Actually no. Javascript doesn't allow for client's FS access for 
security reasons, as noted before.


	What you're probably talking about is IE's proprietary implementation 
and the use of COM objects (and there goes the security), but Andrei

option.

[PHP] Re: string problem

[Rafael]

	Well, if that's the pattern, you can search for >'%< and return 
anything between this and >%'<; if you can use PCRE try something like

  if ( preg_match('/'%(.+?)%'/X', $str, $matches) ) {
  echo  $matches[1];
  }
Now, if the expression can only have: upper-case letters, numbers & "-", 
then use  "/'%([-A-Z0-9]+)%'/X"  instead of  "/'%(.+?)%'/X"

	If "some_func( &$var = NULL )" didn't work, then you're most likely 
using PHP 4.  If that's the case then you could try passing an argument 
by reference in call(real/execution)-time, e.g:


  function some_func( $optional = NULL ) {
···
  }

  some_func();
  some_func(&$my_var);

Note: beware that the directive "allow_call_time_pass_reference"
  _must_ be On in your php.ini
  This functionality is deprecated, since PHP 5 does allow
  optional arguments-by-reference.

preg_replace(), and even if it is the difference would be meaningless; 
and neither I see how writing more lines would be faster.  I also would 
like to know how the use of parse_url() would guarantee that he won't

	Man, I can only conclude you've satanized preg_* functions because of a

they're quite useful the same for easy and complex tasks.  Someone said

that's definetely true.



But of course there is always more than one way to solve a problem.


	Agreed, so Chris may consider whatever he likes the most.  If he, like

is just fine.

[PHP] Re: preg_replace problem

[Rafael]

	Is there any special reason why you want to solve this with regular 
expressions?  As far as I see, there's a couple of problems with your code,

a) $file = dog.txt  should be  $file = 'dog.txt',
b) $getOldValue has the _array_ resulting of parsing the INI file,
   hence you should write $getOldValue, since it's the complete file
   (I won't say anything about performance),
c) you're using a regular expresion to increment the value in a
   specific key/index, and you don't need regexp for that, and
d) you're not saving the whole file, only the "setting" (entry) for
   "today", hence you overwrite the file and leave only "today = n"

What do you think of something like this (a bit changed):
$file= 'dog.txt';
$today   = date("Ymd");
// we read the file,
$getOldValue = parse_ini_file($file);
// set or increment the value in "$today" key,
   @$getOldValue[$today] ++;
// and write back the whole INI file
// note: what we have is an array, not a string
$str_ini = '';
foreach ( $getOldValue as $date => $value ) {
$str_ini .= "$date = $value\n";
}
file_put_contents($file, $str_ini);

Benjamin Adams wrote:

$file = dog.txt;
$today = date("Ymd");

function incDate($new, $date){
//$date = settype('int');
return $new.($date++);
}

$getOldValue = parse_ini_file($file, 1);
$newValue = $getOldValue[$today] + 1;
$oldDate = $today . " = ". $newValue;
$newDate = preg_replace('/(\d+\s\=\s)(\d+)/ie', 'incDate("$1","$2")',  
$oldDate);

file_put_contents($file, $newDate . "\n");

This works with one file but with multi lines I'm having trouble:
if the file has:
20060301 = 34
20060302 = 3
the file after script will be:
20060302 = 4

I want it to preserve the previous lines
so output should be:
20060301 = 34
20060302 = 4

Help would be great, thanks

Hi Gustav!

Gustav Wiberg wrote:

My oponion is that is insane to use global variables. The main 
drawback with global variables is that is very easy to mix up 
variables, and keep track of what variable belongs to what. So an

Ok, so what's your recommendation to solve the problem with using a DB 
class in many other objects/methodes? Think of a DB class:


class DB {...}

And a lot of classes which want to use the DB class:

class Foo {
  function saveChangesInDb() {...}
}

class Bar {
  function saveChangesInDb() {...}
}

- You can use a global "$db = new DB..." and pass it to every 
class/methode,


- you can make $db "global" in each methode,

- you can create a new instance ("new DB") in every methode (but you 
usually only want a single DB-connection per script, and where do you 
pass config-data to access the DB?) or


- use a factory/singleton, which is not so much better than a global 
variable (and again, what about config-data?).



So what's the way you'd recommend and why?


	IMHO, the only way a global variable would have sense is in an 
environment where you can be assured there's a "DBClass" $db instance, 
and that it would never ever be a $db var that's not a DBClass instance 
nor will $db ever be missing.  So, can you guarantee this at the present 
and to the end of times? :)


	I think it would be better to create an instance of $db whatever the 
script you need it, and pass it to every class-constructor as a 
byref-parameter; i.e.


  $db =& new DBClass();
  ···
  $class1 =& new Class1($db);
  ···
  $class2 =& new Class2($db);

	Now, if you insist on using global vars, then maybe, just maybe, it 
would be better to let that byref-param be optional, and check in the 
constructor for a global DBClass instance $db if no DBClass instance was 
given, but then again the problem would be pretty much the same.  Try 
not to rely on global vars, bear in mind that global vars almost always 
give too little info and do not reflect themselves on the function 
prototype --well, if you have a smart IDE/editor that understand PHPDoc 
comments (or something like that) and you do document their existance, 
it might not be that bad, but still try to avoid them.

[PHP] Re: Converting HTML to BBCode [medium]

[Rafael]

	First of all, the back-slashes added before a " character is probably 
because of the gpc_magic_quotes directive in PHP, wich tries to "escape" 
the quotes (pretty stupid, if you ask me), so you must have to use 
strip_slashes() on the string you received, e.g:

  $text = '';
  if ( isset($_POST['text']) ) {
  $text = $_POST['text'];
  if ( get_magic_quotes_gpc() ) {
  $text = stripslashes($text);
  }
  }

	Now, what you're trying to do is definetely not something "basic", 
since you want to replace some non-fixed strings that can either be in 
lower or uppercase (and without changing the case of the rest of the 
text), so basicaly what you have are patterns (some kind of 'rules' that 
shall be followed by the tags)


	By your code I can tell you've already try a little the hard way to 
solve this issue, although it would be quite more laborious than that 
because you would have to search the string almost char-by-char (in a 
figurative way, but pretty much what PHP would be doing) for all the 
tags you want to replace, and possibly be working with two strings: one 
for the original text and other with a lowercase version of it (since 
you cannot search in a case-insensitive way --only in PHP5)


	Anyway, the medium/advanced way (IMHO) would be to use regular 
expressions.  These are quite useful, but also rather cryptic, even for 
advanced users --sometimes it's easier to come up with a new one rather 
than understanding what already exists :p


The function I've test with your test HTML-code is this one:
  /**
   * Performes BBCode conversion for some simple HTML elements
   *
   * @staticvar string  $str_http_valid
   * @staticvar array   $arr_replace
   * @param string  $string
   * @returnstring
   * @since Mon Mar 06 23:44:40 CST 2006
   * @authorrsalazar
   */
  function to_bbcode( $string ) {
static  $str_http_valid = '-:\/a-z.0-9_%+';
$arr_replace= array(

"/(.+?)<\/a>/Xis"
 => '[link=\\2\\3]\\4[/link]',

"//Xis"
 => '[img]\\2\\3[/img]',
  '/<(\/)?(strong|em)>/Xise' => '( strcasecmp("em", "\\2") ? 
"[\\1b]" : "[\\1i]" )',

  '/<(\/?(?:b|i|u))>/Xis'  => '[\\1]',

  '/<(\/)?[ou]l>/Xis'=> '[\\1list]',
  '/<(\/)?li>/Xise'  => '( "\\1" == "" ? "[*]" : "" )',
);
$string = preg_replace(array_keys($arr_replace),
   array_values($arr_replace),
   $string);
return  $string;
  }

	As I mentiones before, keep in mind that reg-exp can be rather cryptic 
sometimes.  Also, this is the raw code, it should be optimized but I'm 
feeling really lazy right now, so it should have to wait for a better 
ocasion.


	It's up to you to decide wheter you'll use this function or not, what I 
would recommend you is not to forget about regexp and give them a try 
later (when you're more familiar with PHP), and I would also recommend 
you to use PREG family rather than EGREP.

Hi,

will be some unknown tags for the to_bbcode() function (even maybe some

should take care of those tags too, with something similar to this:


  $text = to_bbcode($text);// try to convert to BBCode

Re: [PHP] Calling Curt Z, Curt Z to the white courtesy phone please

Also (not sure if all are missing or not):
a) when looking for a specific function in PHP.net you can also use
   other word-separators and not only "_", such as: -, + and space
   (or %20), haven't heavy-tested this, so may as well be others
b) if possible, look for a mirror prepending you country TLD as a
   subdomain, such as http://mx.php.net (it can also be more than
   one for the same country, e.g. http://mx2.php.net, and so on)
c) when reading some parameters use  "print_r()", such as
 print_r($_GET);
d) add a little text about some (repeatedly discussed) basic PHP
   directives such as register_globals and magic_quotes_gpc (and
   try not to rely on the first one and check for the later)
e) when getting a (notice, warning or error) message send it along
   with you posting, as well as the the line that trigger that
   message (and about two lines before and after that line)

	I agree, your regexp are bad (jk)  What you need is a regexp that 
matches an email address.  Look for something like "regexp email" on 
Google (without the quotes) or something similar and you should find 
some regexp to validate an email address; once you have it use it with 
preg_replace() like Bekko did -or its EGREP equivalent.


Example (using the first one I found, a bit modified):
  $regexp = 
'/[EMAIL PROTECTED]/Xi';

  $string = preg_replace($regexp, 'mailto:$1";>$1', $string);

This is a good idea, IMHO of course.


There are some md5 databases around that can be used to get the
cleartext password from the hash if your database is compromised, if
you use this method it's difficult to get the cleartext password
because it depends on the user and you are also validating if the user
exists.


	Well, it's a little hard to obtain the "cleartext" from something in 
MD5-hash, though it's possible via brute-force.  You might as well try 
to use some other method, such as SHA1, combine them or do whatever you 
want to alter the initial clear-text version to obfuscate it (like you

However, i have a question. Which is better?, the md5 function
provided by PHP or MySQL? i used the MySQL function because i didn't
compile PHP with support for hash.


	The one in JavaScript :)  AFAIK, every MD5 function is based on the MD5 
algorithm, so the implementation is rather similar (if not the same)  Of 
course, the result is always the same.

[PHP] Re: setcookie security concerns

[Rafael]

	As far as I see... I can't see any risk.  Cookies are saved in the 
client machine (i.e. the one visiting your site), so any code he might 
send will be used with him only, and it will not affect other users nor 
the scripts in the (remote) server.


	Now, you're not using the input value in anything similar to an eval() 
expression, hence should some PHP code be sent and it would only be 
printed, no harm in that either.


	Inspite of all this, I would really recomend you not to rely on 
register_globals=On, since: it's not a good idea, it's actually 
deprecated (someday it will be removed) and makes your code a little bit 
more confused, since it's not clear where do that variables come from.


> 1. Is he right?
	Yes, and no.  In your specific case someone _could_ send you code 
instead of whatever you're expecting (and you don't validate the input), 
but it would be harmless for anyone other that himslef.


	Beware that the risk of code inserted in cookies, form-input elements, 
the Query string, etc., is real and it depends on the way you use the 
data received, and if you check it and how do you do it.


> 2. How does that work?
	Well, cookies are stored in your (client) machine, so you're able to 
modify whatever content they have.  One way to test this is using 
Firefox and an extension that allows you to edit cookies such as "Add N 
Edit Cookies" (play with the cookie of your own site)


> 3. If so, what do I do to correct this?
	Do not rely on register_globals, and don't ever trust on any input 
given by the user, treat all of them as enemies and check everything 
that comes to your mind --and more ;)


Note: this is how _I_ see it, so I could be ignoring something that 
other people did see.

I don't really understand what you need, but...
- how to find out the number of special (non alphanumeric) characters
  $alpha = '[a-z0-9]';
  $special_chars = preg_replace("/$alpha+/Xi", '', $string);
  * this would replace any alpha-numeric char by... nothing, leaving
the "special chars" only, and strlen() will give you how many are
  * beware that you're saying *anything* other than alpha-numeric chars

- how to match a string that contains less than 3 special chars
  * as I said above, strlen() will give you the number of these chars:
  $num_special_chars = strlen($special_chars);


preg_match('/^[ -~äöüßÄÖÜ]+$/',$string)


will return TRUE if $string consists enterily of the chars between the 
square-brackets.


I hope this helped a little.


urrently im using a function

function valid_username($string) {
   if(strlen($string)<=16&&strlen($string)>5) {
  return(preg_match('/^[ -~äöüßÄÖÜ]+$/',$string));
   } else {
  return FALSE;
   }
}

This allows usernames of 6 to 16 length containing many special chars
and German "Umlaute". But this also allows usernames like "=)/(&%$"
what should not be.

So how to limit the number of special chars? This function should
just return fals if number of special chars > X

	Well, I'm not sure about what you don't understand.  Anyway, 
preg_replace() does "the same" as str_replace(), but using 
regular-expressions instead of just strings.  If you understand how do 
reg-exp work, then it should have no real problem, if the reg-exp are 
the problem then you better read a little more about them (the PCRE

Here is the function in use:

function checkPhone ($Phone)

  $Phone = ereg_replace("[^0-9]", '', $Phone);
  if ((strlen($Phone)) <= 14)
return 
preg_replace("/[^0-9]*([0-9]{3})[^0-9]*([0-9]{3})[^0-9]*([0-9]{4}).*/",
 "(\\1) \\2-\\3", $Phone);

I think my problem is mostly what is returned when preg_replace executes?


	Well, what's inside parenthesis is "remembered" by preg_replace(), and 
you make reference to them using "\\n" or "$n" (where "n" is a number) 
in the "replace-string" (there are some exceptions, but that should do 
for now)  If you look carefuly, there are three expressions between 
parenthesis, and these are what you're referencing via "(\\1) \\2-\\3"


	Though, there's something I don't get it: in your reg-exp your ignoring 
any non-numeric character, but you already got rid of them with 
ereg_replace()... (??)

One last question, considering the above code, would the following code 
be a suitable replacement?





	Actually, you receive $set via GET, so you should use $_GET instead of 
$_POST.  A lot of people use $_REQUEST (wich is a combination of $_POST, 
$_GET and $_COOKIE —check the manual), but I read somewhere that this 
isn't a good practice, though I don't recall why :p


  $set = $_GET['set'];
or even better would be something like
  $set = ( isset($_GET['set']) ? $_GET['set'] : $default_value );

I've used htmlentities() before to filter out user's input, but I don't 
know if that's sufficient to protect from all types of injections -- is it?


	No, it doesn't suffice this way --it does for the script we're talking 
about, but that's because you only use the data as part of the HTML 
code, so no more harm can be done with it.


	A tipical example would be a login script that uses the data as it 
arrives, for example:

  $login = $_POST['login'];
  $passw = $_POST['passw'];
  $sql   = "SELECT * FROM user\n"
  ."WHERE( login = '$login' AND passw = '$passw' )";

In this case, what happens if I send something like
  login: ' OR '1'='1' OR '0
  passw: doesnt care
? (I avoided the ' in the passw, just in case)
Well, we'll end up with an SQL similar to this
  SELECT * FROM user
  WHERE( login = '' OR '1'='1' OR '0' AND passw = 'doesnt care' )
and because of the priority of the AND / OR, we would have 3 separated 
conditions each enough to validate the user, as '1'='1' is true, then we 
have a validated user.


Now, if I can do this, I could change the logic a little...
  login: admin' AND '1'='1' OR '0
  WHERE( login = 'admin' AND '1'='1' OR '0' AND passw = 'doesnt care' )
In this case you should care about ' and " (depending on which one are 
you using)  Again, I read somewhere that the safest way is to use 
(emulated?) "prepared SQL statements", such the "?" SQL-parameters in 
ADODB, PEAR-DB and others.


	By the way, even causing an SQL error that is displayed to the user 
(the whole message or just a part of it) can reveal info that could be 
used to bypass your protection.

[···]
 From what I've read (PHP Cookbook by Sklar and other sources) the 
reason why you don't want to use $_REQUEST is because it holds all the 
variables from six global arrays, namely $_GET, $_POST, $_FILES, 
$_COOKIE, $_SERVER, and $_ENV.


	Actually, the super-global variables used in $_REQUEST are $_GET, 
$_POST and $_COOKIE¹, and though there is a "gpc" directive I'm not sure 
if you can control the order they are read (but my guess would be that 
you do)

¹http://php.net/manual/en/reserved.variables.php#reserved.variables.request

When PHP creates $_REQUEST, it does so by adding the global arrays 
together in a certain order, namely EGPCS.  Normally, this would be OK, 
but if two (or more) of those arrays have a key with the same name, then 
that key value will be replaced with the last value read. For example, 
the value provided by $_GET('mykey') will be replaced by the value found 
in $_COOKIE ('mykey') in generating the value for $_REQUEST('mykey').


So, if you use $_REQUEST, then you can't reply upon where its values are 
derived.


	Well, I still don't remember the reason, but this could be a valid one 
:)  By the way, these are variables (arrays), so you should use 
square-brackets instead of parenthesis to specify an index (e.g. 
$_SERVER['SCRIPT_NAME'])

Re: [PHP] Converting a string

[Rafael]

	Well, you didn't answer the second question, how would you do it?  So 
far I see a pattern: "ignore the lowercase letters at the beginnig and 
add a space before an uppercase" (this won't apply to all field names, 
and I hope you're aware of that), so try something like

  $text = preg_replace('/^[a-z]+\s*/X', '',
   preg_replace('/(?=[A-Z])/X', ' ', $name) );

	Now, a better way, IMHO, would be to use "_" as spaces and write the 
name of the field as you want it to appear (e.g. "First_Name"), so you 
just need to

  $text = str_replace('_', ' ', $name);
--pretty much simplier, isn't?
And... if you want to add a prefix (such as "ps") then make it 
configurable, so it can be changed anytime without effort.


Last comment: you should think about the question you didn't answer, and 
that might give you the solution to your problem.

I expect that I can take a string, like 'psFirstName' and change it to
'First Name'. that way I don't have to worry about what some web
designer named his fields, I can turn them into human readable strings
without having to manually create a new array.

So far I have this

$newKey = preg_split("/([A-Z])/", substr($key, 2), -1,
PREG_SPLIT_DELIM_CAPTURE | PREG_SPLIT_NO_EMPTY);

Which returns;

Array
(
[0] => F
[1] => irst
[2] => N
[3] => ame
)

[PHP] Re: stripping enclosed text from PHP code

Winfried Meining wrote:
I am writing on a script that parses a PHP script and finds all function calls 
to check, if these functions exist. To do this, I needed a function that would 
strip out all text, which is enclosed in apostrophes or quotation marks. This 
is somewhat tricky, as the script needs to be aware of what really is an 
enclosed text and what is PHP code. Apostrophes in quotation mark enclosed text 
should be ignored and quotation marks in apostrophe enclosed text should be 
ignored, as well. Similarly, escaped apostrophes in apostrophe enclosed text 
and escaped quotation marks in quotation mark enclosed text should be ignored. 

The following function uses preg_match to do this job. 

[···]
I noticed that this function is very slow, in particular because 


preg_match("/^(.*)some_string(.*)$/", $text, $matches);

always seems to find the *last* occurrence of some_string and not the *first* 
(I would need the first). There is certainly a way to write another version 
where one looks at every single character when going through $text, but this 
would make the code much more complex.


	IIRC regexp search from left to right but match from right to left, 
hence going trough the string while the first part matches and going 
backwards every time the next part fails to match, and so on for the 
whole expression, that's why "(?>...)", "once-only subpatterns", exists for.


	Now, you're telling (from left to right) to look for "any sequence of 
any characters followed by 'some_string' and, once again, followed by 
any sequence of any characters".  As long as "(.*)" matches it will loop 
the whole string till it fails, once it does it will try to match 
"some_text", if it doesn't it will try to match "some_string" once again 
from the current position minus one and so on, until it matches (or 
"(.*)" fails --at the beginning of the string), after "some_string" 
matches it will repeat the first step for the second "(.*)" on the 
pattern, so the process will be quite slow.

--I hope this has had some sense for you (somehow it lost it for me)

	Also, by default regexp are "greedy", which means "+" and "*" 
meta-characters will go on and on.  In your case, you most likely will 
need to "limit" this behaviour by specifying them as "ungreedy" (that 
is, it will try to match the next part after each "+"/"*" matches), you 
can do this adding a "?" after these meta-characters (e.g. ".+?-")


I wonder, if there is a faster *and* simple way to do the same thing. 


Mhh...  what about something like
  preg_replace('/(["\']).*?(?? it's not 100% accurate, though, if you find something like '\\' it 
will fail --I guess you should replace these before running the regexp


	After trying a little, I found that this code below seems to be quite 
acceptable, you may want to try it:

  /**
   * Returns an array with the identified function-calls found
   * (including "function declarations", e.g. "function my_func")

Ryan A wrote:

Hi,
Like the subject says; I have two questions:

1) Is it possible to detect JavaScript via php... and yes I do know that JS
is client side while PHP is server...but how else to do it?
The reason I ask is before serving an AJAX page I would like to make sure JS
is enabled, if not, serve the other "normal page"... I am sure I am not the
first person to come accross this little problem, how did you solve it?

I have seen some suggestions on google like having a hidden form field  and
using  js to put a value in it, if it exists when the form is sent then JS
is on..if not, its not... but that method is not the best in an AJAX
situation...right?


	You don't specifically what would change in the "AJAX page" (other than 
make use of AJAX)  If it's possible, I would recommend you to serve the 
normal page and include a snippet to modify its behaviour, so you can 
"save the page reloads" (tipical use for AJAX), e.g.

  window.onload = function( ) {
if ( document.frmTest ) {
  document.frmTest.onSubmit = function( ) {
// verify values with ajax before submiting
  }
}
  }
  // "normal version" of the page
This way you only change the behaviour when its supported (of course, 
you would also need a verification for Remote Scripting/AJAX support)


	And I agree with the others about serving the "normal version" first, 
and redirecting via JS (when the behaviour is too different)



2) How can I search in an array for a particular word?

eg: in an array "movie" I have this kind of data:
movie_name=> some movie
cast=> Jim Carrey, Richard Pryor, Eddie Murphy

I want to search on either "Richard" or "Richard Pryor" (must be case
insensitive too)
something like a SELECT with a LIKE %% statement

I have been fooling around with in_array() but not getting anywhere
fast. am I on the right track?
Links, code examples or advise would be as alwaysappreciated.


	First, I would suggest you to re-analize why are you searching in an 
array (of course, you're the only here who knows the reason)


	Second, you may encounter array_filter() useful, this function uses a 
callback user-defined function to "filter" the elements in a given array 
and build a second (which is the value it returns), so you may use this 
function along with strpos() (or some other)

[PHP] Re: unique array problem

[Rafael]

	If what you want is to have a continuos secuential array (i.e. 0=>x, 
1=>a, 2=>f) and there's no need for sorting the values, then you need 
array_values()[1]

Re: [PHP] PHP Standard style of writing your code

[Rafael]

IMHO, vertical aligned brackets can be messy when nesting
relatively-small blocks (and seems to me like a lot of wasted space)
A couple of facts of my codding style:
- I tend to always use brakets, so I ignore the fact that single
  lines/actions can be written without brackets,
- I try not to let lines grow larger than about 100 cols (cannot
  be really done with strings and other thingies, and maybe that
  should remain in the old 80 cols, but it's too litle space), and
- I use a 4 space indentation, and that alone suffices for making
  a block stand clear enough

So, in my case, the code would be something like
  function foo( $x ) {
  // body...
  }
  ···
  $a = foo($b);

So no matter what was actually typed, *I* would see:

Setting aside the fact that you're completely wrong about your

What, in your mind, is the advantage to putting the opening brace on
the same line as the function call, logic statement, etc.? (Btw, this

Re: [PHP] PHP Standard style of writing your code

[Rafael]

	It's kind of ironic that you didn't split that big chunk of text into 
paragraphs, don't you think? ;)


	Anyway, yes, I was referring to visual space, we all know that is more 
clear the more you can see the code, that's why we don't let rows go 
insinely long (well, wide actually), and that also applies for the 
"vertical viewport" (rows also, not only columns)  That's why *I* find 
it a waste of (vertical) space.


	But, as we all know also, coding style is just that, a style, yet 
another matter of taste --of course, there are some basics that should 
always be present for the sake of clarity (such as indentation, 
comments, and an empty line here and there as logic-separator), or 
that's what I think, anyway --let's not discuss about this, wi'l ya?

I'm struggling to get my head around this concept of 'wasted space' with 
regard to software code.  What is it that's getting wasted, exactly?  If 
we printed our programs on paper it would be wasted trees (page-space) 
but I almost never do this and I don't know anyone who does except 
banks.  It could be seen as a waste of disk space, but only at the rate 
of a few bytes per code block, carriage return plus perhaps a couple of 
tabs.  What we must be talking about here is a waste of visual space.  
How does visual space get wasted?  Isn't it possible to waste something 
only if it's in finite supply?  I guess it's being wasted if it's 
something valuable that's not being used.  However, the urge to add 
whitespace to spread things apart is done with the intent of making code 
easier to read, so that seems like a use, not a waste.


OK, OK, I'll stop.  Think I'll go out and get wasted~

	Thanks for your reply.  Paul Novitski already "talked" with me about it

I'm usually aware what people are talking about (since I've wrote the

	Well, if you're asking for some recommendation on how to show it, I 
would suggest to use lists (either ordered -OL- or unordered -UL- 
depends on you), or maybe even data-lists (DL), so you would get

  +- parent 1
  |  +- child 1
  |  \- child 2
  +- parent 2
 \- sub-parent1
+- sub-child 1
\- sub-child 2
into something like
  
 parent 1
 
   child 1
   child 2
 

 parent 2
 
sub-parent 1

  sub-child 1
  sub-child 2

   
 

  

	Now, if you're asking for code, send what you've tried so far, and 
maybe someone will be able to help you (either correcting your code, or 
sending another way to do it)

	Well, if I understood correctly, and the IP's first 3 segments are all

  SELECT
SUBSTRING(ip, 1, 11) AS ip,
COUNT(1) AS cantidad

the other suggestions.

Re: [PHP] Getting totals

[Rafael]

	I really doubt you need to use strstr() here, since it will return a 
string (_if_ the 'needle' is found in the 'haystack')[1], I guess you're 
looking for strpos() or something similar.


	Now, you said that you have this IPs on your database, so why don't you 
count the IPs directly on your database?  If the examples you gave are 
real and the first 3 segments of each IP are the same, then you could 
group your records, clasify and count them.  For example, if you were 
using MySQL, you can count them with something like


  SELECT
SUBSTRING(ip, 1, 11) AS ip
COUNT(1) AS counter
  FROM table
  GROUP BY ip
  ORDER BY ip ASC
*NOT tested

which should give you something like
  ip  | counter
 -+-
  192.168.100 |   1
  192.168.101 |   2
  ··· |   ···
  192.168.110 |  11

You've got the parameters mixed up. strstr is (haystack,

[PHP] Re: How to re-order an array

[Rafael]

	Since you asked for some theory... theorically, you won't rely on 
javascript to prepare/validate/whatever some data to the server, that's 
what server-side scripts are for.
Note: you may use JS to make things quicker if possible, or to 
pre-digest the data, but you shall not rely entirely on JS.


	You say that not all browsers support the javascript functions you 
pretend to use, and that not all them support Ajax either.  That sounds 
just like saying that not all browser will have javascript enabled 
--that's why you shouldn't rely on javascript


	Although, this isn't a javascript list, why don't you send whatever you 
were trying to solve this issue? the code that uses JS functions not 
supported for all the browsers that will potentially run the script (as 
well as what these browsers are)  Most likely someone will be able to 
help you this way.

Array.push(), Array.pop(), Array.shift(), Array.unshift().


	Ok, so what are your intended browsers?  According to what I found, 
these functions are part of ECMAS 3 standard, and are available in FF 
1.0, Netscape 4, e IE 5.5 (unshift until IE 6) --as always, M$ gives the 
problems.


You might try to implement them yourself, such as...
  // "object detection" for shift function
  if ( undefined == Array.prototype.shift ) {
Array.prototype.shift = function( ) {
  var  val = this[0];
  for ( var  i = 0;  i < this.length - 1;  i ++ ) {
this[i] = this[i + 1];
  }
  this.length --;
  return  val;
} // shift()
  }
  // "object detection" for unshift function
  if ( undefined == Array.prototype.unshift ) {
Array.prototype.unshift = function( ) {
  var  args = arguments,
   len  = this.length + args.length;
  this.length = len;
  for ( var  i = len - 1;  i >= args.length;  i -- ) {
this[i] = this[i - args.length];
  }
  for ( i = 0;  i < args.length;  i ++ ) {
this[i] = args[i];
  }
} // unshift()
  }

  var  x = new Array( 'z', 'b', 'c', 'd' ),
   y = null;
  document.write("→ "+ x.toString() +"\n");
  y = x.shift();
  x.unshift('A', 'a');
  document.write("⇒ "+ y +" ⇒ ["+ x.toString() +"]");

Note: tested only in Fx 1.5.0.3 (as _shift & _unshift) with secuential
  arrays (and not associative/hash arrays)

I thought that if I used Ajax, php could use its push and pop, shift and 
unshift functions, but not all browsers support the asymetric requests.


	Well, that seems too complex to solve your problem, but if you want to 
try it, you may use the same "object detection" above and implement 
those methods with PHP (e.g. unshift in IE 5.5, or all of the functions 
you mentioned in IE 5.0)


I do screen in the server. But I force the user to have javascript 
enabled and force the form to submit using javascipt, and have a unique 
id as a javascript variable
that is sent along with the form in a hidden field to identify the 
source of the form data. I never use get requests unless they are 
appended to anchor tags, even
in  forms that are not processed by the server (I.E. running javascript 
code with user supplied arguments to functions via form fields, in which 
case an action attribute

isn't even necessary, and like wise a post or get method).


	It's basically the same problem, you shouldn't rely on javascript for 
your page to actually do something.  If I don't have JS enabled (for 
whatever the reason) I won't be able to do anything on it.  JS should be 
used only to _add or complement_ functionality.

Now, if it's just for practice, then you need a little change in you 
code, since  strtoupper('\\2')  will give '\\2' (i.e. does nothing) and 
the letter will remain the same.


	I meant, since *strtoupper('\\2')* is evaluated _before_ being included 
in the string (used as replacement), i.e...

  preg_replace('/(^)(.)(.*$)/', strtoupper('\\2') . '\\3', 'yikes!');
is evaluated as
  preg_replace('/(^)(.)(.*$)/', '\\2\\3', 'yikes!');
since *strtoupper('\\2')* => *'\\2'*, that's why I said it does nothing.

	In the code sent, *strtoupper()* is passed as a (literal) string which, 
combined with the "e" modifier (at the end of the expression), gives the 
effect you were looking for (i.e. the "replacement string" is evaluated 
--as code-- before it actually replaces the string found)

	As for the value of Content-Type it doesn't matter, you only have to 
specify an unknown (MIME) type so the browser won't know what to do with 
it, hence forcing to download the file.


	As minor notes (after reading a bit the RFC)... "Expires" is expected 
to be a date, not a number, and "Pragma" value conflicts with 
Cache-control, since...

   public
  Indicates that the response MAY be cached by any cache, even if it
  would normally be non-cacheable or cacheable only within a non-
  shared cache. (See also Authorization, section 14.8, for
  additional details.)

	Also, it seems we're given a wrong use for "must-revalidate" (me 
included), that or I misunderstood the RFC documentation --I didn't even 
found "pre-check" & "post-check".  Content-Disposition is not part of 
the HTTP standard and Content-Transfer-Encoding is ignored, since both 
seem to be for e-mail usage (LOL) --and it's possible values are 
"quoted-printable" o "base64"--.  Finally, "Content-Length" and 
"Content-Type" seem to apply only if "had the request been a GET".


	Interesting what you learn reading the RFCs, too bad they're too long 
and sometimes not that clear.

[PHP] Re: can I do this: update table while selecting data from table?

[Rafael]

	As far as *I* know, yes, the SELECT statement is excuted at that 
particular moment, and any further execution will be independant of your 
initial (SELECT) query.  Was there any problem?

Safer, yes. And it'd be even better to do 24 === "24/7", in which case 
you don't need a function call, it's probably faster (I'd imagine that 
comparing equality is faster than finding out HOW close it is like 
strcmp does), and as I mentioned, easier to read.


	The only possible values of strcmp() are: 1, 0 & -1.  Hence, basically 
both are doing the same, the difference would be the value they return, 
one returns a boolean, and the other an integer --strcmp() doesn't 
compare "HOW close it is" one string from the other, you might be 
talking about levenshtein(), similar_text(), soundex(), etc.


	As for the speed, it would be "===" (0.0007), "==" (0.0008) and lastly 
strcmp() (0.0012) in a quick test with 1000 comparisons.  So yes, an 
operator is faster than a function call (kind of obvious), but my point 
was to use strcmp() instead of any of the operator based solely on 
experience with string comparisons, that was all, and I certainly don't 
think that would be a bad advice, but I think that say something like 
"use the operator, it's faster" it is a bad advice, since you're not 
explaining how does it work (e.g. "automatic casting") which could led 
to unexpected results, don't you think?  Anyway, that's something that 
you find only in "special cases".


If you need to ensure type, (so that 0 == "foo" doesn't return true), 
then you can use ===.


Using a function call that does more than you need when there is an

just like the (stranger) case of the loop

  for ( $c = 'a';  $c <= 'z';  $c ++ )
  echo  $c;


I didn't say that it had the same behaviour, only the same goal; finding 
out if two strings are equal. strcmp does MORE than that, it also finds 
out how CLOSE they are. You almost never need that information, in which 
case you're wasting processing time with a function call that does 
something that you don't need. Come on, face it, how many times have 
done anything with strcmp's return value OTHER than checking that it's 
zero? I bet the cases are fairly rare.


	I already "talked" above about what strcmp() does.  As for the cases 
that I've used strcmp() to know if two strings are equal, *obviously* 
they're more than those I've used strcmp() to see what string is 
"bigger" than the other ("custom-sorting" is the only case I remember)


Not to mention the fact that it leads to harder to read code. Which 
of these has a more readily apparent meaning?


if ( strcmp($foo,$bar) == 0 )

if ( $foo === $bar )


That might be true, either way you need to know the language to 
understand what the first line does and that the second isn't a typo.


=== is a basic operator. One has to assume that somebody writing code is 
at least familiar with the basic operators. If not, well, asking them to 
know what the function strcmp does and what it means when it returns 
zero is just as onerous. If not more so. And again, strcmp wastes time 
calculating information we don't NEED.


	"===" is not that of a basic operator, not even in PHP.  And "==" looks 
like a typo for those new to C (or similar), so they have to *learn* 
what does it mean, the same goes for strcmp() --which may be even more 
familiar than "===" for some people (me included)

	Well, it depends what "usually is" (can be) before what you want to get 
and the regex family your using.  If it's PCRE, you may try something 
like "\b\d{4} [A-Za-zÅØ]{2,20}"  \b = "word boundary", it's basically 
a word separator and it's not included in the result you get (since it's 
more a "position" rather than a "string")


Also, you may notice a couple of 'special' characters in my expression 
'Å + Ø'  By putting them in they seem to work fine, but is this the 
best way of doing it?


	I think it is.  IIRC what you define in a "class" (i.e. between 
square-brackets) is quite fast; e.g. "[ab]" fastest than "(a|b)", is 
that what you were asking?

Re: [PHP] "!" in front of a variable?

I took me a little while to notice that it wasn't a function

	It's just as Jay said, it's calling "function" with those arguments, 
where '!$var2' extends to '!(bool)$var2' or "treat/cast this value as/to 
boolean, and pass it's inverted value" or "NOT $var2".

The question I have is on the 3rd input variable, what does the "!" in

Hmmm. Looks like a weird mistake, to be sure. If $var2 is boolean it should
pass the opposite of its current state. Is $var2 a boolean? It is being
passed twice here, once AS and once AS NOT.

[PHP] Re: "isset" or "array_key_exists"?

[Rafael]

	After a little test, although the results are not conclusive, I would 
say that isset(), and also that array_key_exists() may even use isset() 
(or similiar) internally as a first step -let's remember that isset() 
only does a "fast search" and it returns FALSE if the value is NULL; on 
the other hand, array_key_exists() returns TRUE even if the value is 
NULL-  I said this (as an hypotesis) because the difference in time when 
the key exists and when it doesn't is quite big, sometimes about 10 
times slower.


	The script I used to test it was this (it is assumed that any "extra" 
operation affected both loops equally)

 array( 1 => -1 ) );
$num_oprs = 1000;


$start= micro_time();
for ( $i = 0;  $i < $num_oprs;  $i ++ ) {
if ( isset($arr_test['key'][1]) ) ;
}
echo  'isset: ', micro_time() - $start, "\n";


$start = micro_time();
for ( $i = 0;  $i < $num_oprs;  $i ++ ) {
if ( array_key_exists(1, $arr_test['key']) ) ;
}
echo  'array_key_exists: ', micro_time() - $start, "\n";



function micro_time( ) {
return  preg_replace('/^0(\.\d+) (\d+)$/X',
 '$2$1', microtime());
}

 ?>

Re: [PHP] Re: "isset" or "array_key_exists"?

[Rafael]

	Actually, it doesn't have much sense that it creates a variable (or 
index), though it had sense why wouldn't be so easily detected, so I 
printed the array after the loops and there's no new keys.  I think that 
if that was the case, it was definitely a bug that has been corrected 
(PHP 4.4.0)

*Note: I guess that's because isset() is not a function, but a keyword

	That was very ilustrative Rob, thanks for the info (it's the kind of 
thing I shouldn't forget)


Satyam wrote:
[···]

isset is a keyword in PHP
array_key_exists() is a function.

Keywords are much faster than functions due tot he overhead functions
occur for setting up the stack.

If you don't care about null values, use isset(). If you do, use
array_key_exists().

The reason isset() doesn't return true for null entries has been
described in the past. The official stance was that null is not a value.


[···]


Accessing a non-existing element, doesn't create it? Thus, using isset 
to evaluate whether an element exists creates it, though with a null 
value.  If you make a first pass on the array with isset, a second pass 
with array_key_exists would give true for all of them though isset would 
give the same results as in the first pass.  I think this happened to me 
once when I went through an array with isset or isempty or some such to 
make some calculations and then on the second pass, when I printed it, I 
got lots of empty cells that were created empty in the first pass.

Just a couple of questions/points to make all clear:

b) if you want to allow (or "not fail with") "-", put it as the fist
   (or last?) character of the class, since it is used to define
   ranges, and this avoids misinterpreting its meaning
c) what regex family functions are you using and what would be the

RE: [PHP] Php.ini file missing

[Rafael Perazzo]

I think that you have this problem because your
sendmail is not running. 
Try to run your sendmail (probably this command
/etc/rc.d/init.d/./sendmail 
start- Note that before the name sendmail you have
two chars ./) 
and I think your problem will be fixed. Then test your
script again to see 
if it's working. 

If this do not work, write again, I'll be very happy
to help the php 
community.

Re: [PHP] creating MySQL Users

[Rafael Perazzo]

Try this query : 

   $query = "GRANT SELECT,INSERT,UPDATE,DELETE,ALTER
";
   $query .= "ON $username ";
   $query .= "TO $username@localhost ";
   $query .= "IDENTIFIED BY '$password';";

Make sure that you put a blank space after each
string, except the last one. 
I hope this work!

[PHP] Error: 1 is not a valid mysql link resource

[Rafael Steil]

Hi all.  
With php version 4.0.1, I made a database class. I use a function called 
connect() to open database connection to mysql, and the link resource is 
stored in $GLOBALS["CONNETION_ID"] global variable. All of code work 
perfectly, with no any problems..
But when I upgraded to php version 4.0.6, the code wasn't work at all. The 
error returned is 

Warning: 1 is not a valid MySQL-Link resource in 
/usr/local/apache/htdocs/Produtora/manole/config/site/database.class.php on 
line 190

the line 190, in this case, is just

$data = mysql_query($sql, $GLOBALS["CONNECTION_ID"])

it is the same code that works with php 4.0.1,,  The link resource is valid ( 
at least I think that ), because when I do

 echo $GLOBALS["CONNECTION_ID"];

the return is

Resource id #1

does anyone knows the problem???

thanks anyway,
Rafael Steil

Re: [PHP] file system question

[Rafael Steil]

Well, this is a problem.. with perl, you can use suidperl, but not with 
php.. the most easyest way is to give write permission to apache user to the 
directory you want to upload the files...

I have never installed PostgreSQL, but I have installed Apache and PHP
together. Three suggestions:

1. Forget the installers. They are worthless, since all you're doing is
adding or editing a few config file lines, plus adding a PATH variable.
2. Where and how you change those files is important, though, so you need
to
google the version of php and apache you are installing and follow those
directions. It's tricky the first time, though. Be patient.
3. Start apache during your testing through a command-line. The error
reporting is much better on the command-line.

Also, really try not to put your PHP library in your System32 folder. This
is bad practice. Edit the PATH variable to point at where it should be
looking for the library.

WAMPP makes apache and php installation stupid easy (MySQL too, but you

1. A user sends a request to your server to get a compressed file
2. You compress the file on the server
3. I want to send back the file to the user

Re: [PHP] Query result column to array

[Rafael Mora]

Hi!!

What I do is just this:

$_ar = array();


  while($_field = mysql_fetch_row($_result))
  {$_aloft["$_field[0]"] = "$_field[1]";}

  while(list($_key,$_val) = each($_ar))

I'm looking for a native method for taking all of the values from one

Procedurally, I'd tend to want to do this:

query("SELECT my_id FROM my_table");
while ($row = $query_result->fetchRow())
   $my_id_array[] = $row['my_id'];
?>

Heck, ColdFusion has the ValueList function which does exactly what I
want (of course, it returns a delimited list [string], not a native
array, but the one-step method is there).  Is there anything in
PHP-land that does that?  Or am I pretty much stuck using some
variation of the code above?

But can you download it correctly? Is it just the download box that shows

Or is it so that you actually is doing what you do below readfile()

Re: [PHP] send a file or stream

[Rafael Mora]

Thank you very much Curt!, I'm tests right now with this. The client is not
a web browser, it is an application that calls the .php file with $_GET
params, and the app waits to receive the file compressed, this is the way I
want it to work!

I'll let u know about this. But anyway thank you

Rafa

PS: what is that ob_start though?

Unlike my recent posts, this could be a candidate for using ob_*

There is no need to compress it first, just use ob_start('ob_gzhandler');

if the client supports a compression method, no special things are
needed and the content sent is compressed otherwise it is sent without
compression.

see http://php.net/ob-gzhandler for more info.

HTH,

So you can have something like this:

$jjj = new ISS();

u just need to be sure that u are using the exact name of the class, it
