Re: [Fwd: Re: [PHP] Some error in file upload.]

[Marco Tabini]

Naif,

I think your problem is related to register_globals. The authors of the
book probably based their scripts on a version of PHP that had that
option turned on by default, but as 4.2.0, it's been turned off as it is
usually considered a security risk. So, either use the superglobal
arrays (like $_POST) to access your HTML form variables or turn
register_globals on in your php.ini file.

Cheers,


Marco

RE: [PHP] Using Ping (was: using cookies)

[Marco Tabini]

I took the liberty of changing the subject of your e-mail because this
way everyone can follow it better.

Well, you can execute the ping command directly from within PHP and then
parse its input. For example:

/dev/null"), $a);

if (count ($a) && $a[1])
echo "success";
else
echo "failure";
?>

This will work only under Unix, but you can very easily adapt it to
whatever os you need, as long as it supports pinging from the command
line.

Probably just a problem with register_globals

Re: [PHP] php and caching

Caching is usually managed through a set of headers--for example:



You can use these in the pages that are dynamic and omit them in those
pages where you want to keep the information.

Re: [PHP] spawing new PHP process

[Marco Tabini]

Assuming you're working on UNIX--you need to use one of the execute
functions (search for exec in the manual). You can spawn a separate PHP
in the background in a number of way, for example, by using the screen
program. 

If I remember correctly, you can't instantiate it directly and run it in
the background because PHP does not close stdout and stderr--but this
might have changed and/or I may be mistaken (nothing new there).

I'm interested in spawing a new PHP process -- if that's the correct terminology.

The situation is that I've got a very slow loading page, where, for example, I'm using 
PHP to send, say, 1000 emails.  The user clicks submit, and, although PHP is firing 
out the emails, it appears to the user that page is hanging.  I'd like to somehow send 
that process to the background and let the page load straight-away.

In another scripting language I've used, this function was called "spawn."

Do we have something like this in PHP (I know we do!! Just can't find it.) I've looked 
through the docs but don't see what I'm looking for.

Thanks in advance.

Re: [PHP] FTP and security

[Marco Tabini]

Rich,

Why don't you create an ssh tunnel between your two boxes and then
perform you ftp connection through there? This way, the connection would
be secure and you could impersonate whichever user you need to.

There is also a secure version of ftp, but I don't think that it can be
instantiated directly from PHP, and you would therefore have to run it
from a shell, which would give the same problems you have with ssh now.

My company, as a matter of policy, closes the ftp ports of the servers in the DMZ. 
However, I am not convinced that this is necessary, given the advent of very secure 
ftp servers. I would appreciate any comments on the security of an open ftp port. To 
relate this to php, I am ready to give up trying to make my 

system("scp ..");

code work, because I will have to give the apache user more permissions than I am 
comfortable with. So, I am thinking fo using php's ftp commands instead. I see nowhere 
in the documentation however, if the ftp_connect can be done via the ssh transport 
mechanism. Or, is this unnecessary, and can I use ftp (with plain text user and 
password passed to ftp_login()) on port 21 without worrying about getting hacked? 

muchas gracias

Re: [PHP] FTP and security

[Marco Tabini]

Well, as far as I know you need to have sshd (or an equivalent) running
on the receiving end. Then, on your server you call up a command like
so:

ssh -f -2 -N -L {source-port}:{end-address}:{end-port}
{sshd-server-address} -l {login}

This command causes ssh to create a secure tunnel that goes from
source-port on your server to end-address:end-port through the ssh
server {sshd-server-address}. Clearly, {sshd-server-address} and
{end-address} can be the same computer, but not necessarily--as long as
there is a direct route between the two and you can consider that route
secure.

Once you've established the connection, you can connect to your local
box on the {source-port}, and your data will be transparently (and
securely) redirected to the new box.

For example:

ssh -N -2 -f -L 3307:my.mysql.box:3306 my.mysql.box -l mysql_user

creates a secure tunnel for connecting to a remote MySQL server
securely. After you've established the connection, you can use
127.0.0.1:3307 on your local box to connect to MySQL and your data will
be transported securly to the other computer.

Hope this helps... a more complete (and probably more accurate)
explanation would take a long time, but if you look around on the Net
you should find plenty of resources.

Cheers,


Marco

Marco,

Would you have any examples for using an SSH tunnel? I'm using fsockopen
to get data from proprietary server software (just returns data to me in
different formats) and I would like to have it secure. I'm just not sure
how I could incorporate that.

Thanks,

Bryan

Re: [PHP] URL hiding

[Marco Tabini]

If index.php is the index page of your website, then you do not need to
specify it at all.

i.e. www.whatever.com/index.php?uName=Kris

is functionally equivalent to www.whatever.com?uName=Kris

A way to get rid of the variables passed in the query string is to use
POST instead of GET as the method of your HTML form.


Hope this helps,

When I pass variables to a new page in the address bare of the browser it looks like

www.whatever.com/index.php?uName=Kris&passWd=1234

How can I hide this so it's just

www.whatever.com/index.php or even better just

www.whatever.com

Re: [PHP] URL hiding

Then the only solution I can think of is to make them part of the POST
variables somehow--ie. through a hidden field, which you can even fill
dynamically with Javascript. AFAIK that's the only way.

I already use POST as the form method.
I know
www.whatever.com/index.php?uName=Kris can be the same as
www.whatever.com?uName=Kris

I just want to get rid of the ?uName=Kris part on the end
I still need the variables to be passed I just don't want the user to be
able to see them.

Thanks for your help

Re: [PHP] php and https

[Marco Tabini]

Is this related to PHP? Or are you getting the error from your browser?
In that case, are you using IE? If so, it might be a bug with IE--I've
seen it discussed in a few mailing lists.

Otherwise, it might indicate that the web server you're connecting to is
not configured properly.

Re: [PHP] Call to undefined function: mysql_foo()...

Is it possible that phpBB is using a different copy of PHP?

Re: [PHP] PHP and the PDFlib

[Marco Tabini]

Take a look at the iText library--it's a Java library, but you can build
your Java classes and then instantiate them through PHP by executing
them as external apps.

That's what we use to personalize copies of our magazine.

Re: [PHP] Max File Size

[Marco Tabini]

Are you sure you're looking at the right php.ini? Try calling phpinfo()
and check where PHP is looking for the ini file.

Hi,

I'm having a problem uploading files greater than 2mb, but I believe the
problem is related to php.ini.

UPLOAD_MAX_FILESIZE in my submit form is set to 1000.  Also, I set
upload_max_filesize = 1000 in php.ini.  After changing php.ini, I
stopped and then started httpd.  I thought this was enough to be able to
upload files greater than the default 2mb.

Even though php.ini has been changed, when I check phpinfo.php, I see that
upload_max_filesize is still 2mb and my file is not being uploaded.

Can anyone tell me what I am missing here.

Thanks,

Roger Lewis

Re: [PHP] force download with header()

[Marco Tabini]

Are you using Internet Explorer? Then it's a "feature" of IE--it ignores
the disposition headers sent by your server because its registry tells
it that PDF files must be "viewed" inline. There's a way around it,
although it's a bit kludgy--I wrote a small article about it that you
can find here (it's in PDF format, as well): 

http://www.phparch.com/issuedata/2002/december/sample.php

Essentially, you're telling IE to download a file with the extension
".pdf " (not the space) so that it can't match the MIME type anymore and
will follow your suggestion of downloading the file instead of
displaying it inline.

Hope this helps!

Cheers,

Re: [PHP] Question about "if" statement evaluating (0=="string")as TRUE

[Marco Tabini]

I think this is happening because you're comparing apples to oranges.
Your first comparison causes an integer to be compared to a string.
Because the string "string" evaluates to the integer value 0, the
comparison succeeds. The manual recommends the use of the identical
comparison operator (===) instead, or--better yet--the strcmp() function
when comparing two strings.

Cheers,


Marco

Is that becuase PHP is not properly comparing the numerical value with

Re: [PHP] Fw: Formatting dates (from MySQL)

[Marco Tabini]

You should be able to use strtotime() to transform the datetime string
into a UNIX timestamp, which you can then format back using date().
However, this is a very circuitous way--either use SQL to format it or,
if your DBMS supports it, have it returned already as a UNIX timestamp.
The actual SQL commands depend on which DBMS you actually use.

Hey there,

I was just looking at the date/time functions
(http://www.php.net/manual/en/function.time.php) and I can't seem to find a
function that can format a date that is supplied in the format of a DATETIME
column.

So, I was wondering, is there a function that can format it properly or
should I let the database handle the formatting (I'm really new to SQL, I
didn't come across anything to mod in the select statement yet). I could
ofcourse split it on space for a time and a date var and then split the date
on -'s for years, months and days but efficient is something else I think
:-) In the archives I saw some examples doing exactly that, but nothing with
a single function (unless home defined ofcourse).

Kind regards and TIA

Using MS Win 98 / Apache Server:

I'm trying to test a form box using the php mail() function.

All is well when I fill in the text boxes and hit submit.

I receive the e-mail.

The form action in the html page is:

http://localhost/getform.php";  METHOD="POST">

_Now_

when I copy both of those files which are:

1. The html file for the form box

- I have now changed the form action to read:

http://www.narrowsburg.org/getform.php";  METHOD="POST">

and

2. the .php file for the script

and publish them to my site which is hosted on my ISP's MS Server, and then
input data in the form boxes and hit submit:

I now get the following:
..
NOTICE: Undefined Variable: name in
d:\inetpub\www.narrowsburg.org\getform.php  in line 7


Then, when I check my e-mail I get a message with no input data from the
variables like the name, e-mail, address, etc.

Thanking all in advance who might help me out.

Re: [PHP] Undefined Variable

[Marco Tabini]

Hey Anthony--

It's definitely a register_globals problem. Your ISP has turned it off
because it's generally considered a significant security risk.

The best way to solve it is to use the superglobal $_POST to access your
post data. In your PHP script, change all the variables that you take
from the form into their $_POST[''] equivalent (see below for a rough
example--I put the assignments at the beginning because I wanted to
touch your code as little as possible). Also, keep in mind that you're
not performing any checks on the data--I'm sure you want to do it once
you've sorted the current problem out, but the way it is now you're
leaving yourself exposed to a number of possible attacks.

$thename = $_POST['thename'];
$email = $_POST['email'];
$description = $_POST['description'];
$bizname = $_POST['bizname'];
$contactname = $_POST['contactname'];
$phone = $_POST['phone'];
$email = $_POST['email'];
$mailing = $_POST['mailing'];
$town = $_POST['town'];
$state = $_POST['state'];
$zip = $_POST['zip'];
$cat = $_POST['cat'];

if (($thename == "") && ($email == "") && ($description == "")) {
 header("Location: http://localhost/n_proserv_x.html";);
 exit;
}
$msg = "This e-mail was sent from:\n";
$msg .= "Sender's Name:$thename\n";
$msg .= $thename ."'s business name is:$bizname\n";
$msg .= "The contact person is:$contactname\n";
$msg .= $thename. "'s phone number is:$phone\n";
$msg .= $thename. "'s e-mail address is: $email\n";
$msg .= $thename. "'s mailing address is: $mailing\n";
$msg .= "Town: $town\n";
$msg .= "State: $state\n";
$msg .= "Zip Code: $zip\n";
$msg .= $thename."'s category is: $cat\n";
$msg .= "and the message is:  $description\n\n";
$to = "[EMAIL PROTECTED]";
$subject = "Narrowsburg Chamber of Commerce";
$mailheaders = "From: $thename\n";
$mailheaders .= "Reply to:$email\n\n";
mail($to, $subject, $msg, $mailheaders);
?>

Re: [PHP] Session: I RTFM

[Marco Tabini]

I haven't followed the rest of the thread, but how about using a
function?

function getvar ($varname)
{
if (isset ($_POST[$varname])
{
$_SESSION[$varname] = $_POST[$varname];
return $_POST[$varname];
}
elseif (isset ($_SESSION[$varname]))
return $_SESSION[$varname];
}

session_start();

// You don't need session_register anymore

$familyname = getvar('familyname');


and so on--just one line per variable.

Hope this helps.

The FM manual says:

"$_SESSION (or $HTTP_SESSION_VARS with PHP 4.0.6 or less) is recommended"

So I am using "PHP Version 4.1.2" (and "4.2.3" on my localhost to test offline)

Ok. I quit using $HTTP_POST_VARS["familyname"].

With a little rethinking, I have this working, I hope.

Now ... is there a cleaner way to assign my variable "familyname"?

Pseudo code:

if _post["familyname"] exists set session variable
 (no sense in setting it until I post it)
if _session["familyname"] exists, $familyname = $_SESSION["familyname"];

I'll have about 30 variables. Going to be alot of lines. There must be an easier, 
cleaner way?


";
}

if (isset($_SESSION["familyname"]))
{
$familyname = $_SESSION["familyname"];
echo "yay session works, \$familyname= $familyname";
}

Re: [PHP] Session: I RTFM

Single quotes are normal strings. Double quotes are strings in which
substitutions can take place. For example:



Double quotes also expand escape strings (e.g."\n") whereas single
quotes don't.

What is the difference between:
$familyname = getvar("familyname");
and
$familyname = getvar('familyname');

What do single quotes do, as a general rule, that double cannot (he asks remembering 
something, but not sure what)?

I used the mail function this weekend and set the mail contents like this:

But in the actual e-mail sent, the link was plain text,not a link.  Can I

Re: [PHP] PHP shell scripting not working right?

[Marco Tabini]

In Unix you need to specify the working folder when you are launching an
executable, otherwise Bash will try to look into its search path, which
does not include the current folder. Try:

./test.php

That should work. BTW--running "test" by itself only *looks* like
hitting enter--it's really a valid command. Try man test for more info.

It's saved as test.php and CHMODed to 777.  When I type "test.php" at

What i want to get from this is array

words
 [Today] => 0
 [Is] => 6,30
 [Very] => 8
 [beautiful] => 12
 ..

Can somebody please help me with this. Those nubers are
position of special word in above sentence. If word repeates
i want to have both positions saved in same row like word is.

I tried something but i think it's to lame.

RE: [PHP] Divide into words

[Marco Tabini]

John,

I'm not sure this will work if there is more than one space between
words.

Also, my previous example won't work if there are duplicate words
(although it's easy to make an array out of each word and solve the
problem), nor if the words are delimited by any character other than
spaces, in which case regex are probably our best bet.

Cheers,

Well you could've at least shown us what you had so far instead of
letting us solve the problem for you:

$string = "Today is a very beautiful day and the sun is shining";

$words = explode(" ",$string);
$pos = 0;

foreach($words as $word)
{
if(isset($w[$word]))
{ $w[$word] .= ",$pos"; }

Re: Re[2]: [PHP] Divide into words

[Marco Tabini]

Yes, but my example was geared towards trying to work through a more
generic scenario. I'll bet if you try using perl regex with callback
it'll be even faster.

Hi!

I have dome almost the same

$input = 'Today is a very beautiful day and the sun is shining';

$output = array();
$words = explode(' ',$input);

$cur_pos = 0;
foreach($words as $word) {
if(!empty($output[$word])){
$output[$word] .= ','.$cur_pos;
} else {
$output[$word] = $cur_pos;
}
$cur_pos += strlen($word) + 1;
}
unset ($word);


but i thought if there is some better way. I also tried
Marco's example and adjust it a little bit to get the same
results. And here is some benchmark i have.

with this example i get  0.0024310350418091
and with Marco's i get 0.0034389495849609s

So using two array is faster anyway. Probably of explode
speed.

Re: [PHP] key pairs

[Marco Tabini]

This is a bit crude but should work:



Note that I made a bunch of assumptions here--that the data is always
properly formatted, that there is only one record in the $data, and that
you will later manipulate the key names so that they will actually work
as database columns. Still, this way you can manipulate each value
directly in the function, which is something that I always find very
practical, so you can add whatever additional checks need to be
performed.

Hope this helps!

Re: [PHP] Resource limit/performance questions

[Marco Tabini]

IMHO it depends on the amount of operations you have to perform on your
rows. If manipulating 2,600 rows takes several seconds, then either
you're performing some really complicated data manipulation or your db
could use some optimization. I have an application that manipulates
~150,000 rows on a Pentium II 350 MHz and that takes at most half a
second (although I'm doing really simple statistical stuff).

I'm working on a php/mysql ap, which looks as though it will be dealing
with an average of

160,000 rows of short text entries =
32 megs of drives space

Anybody have ideas about what if any limits I might hit? And how I might
be able to determine any limits at this point when we have only 2 weeks
(.6 megs and 2600 rows) of what will be 2 years of data? I have full
access to my linux server. I notice that when executing one set of
statements for one page, it is now using in the 80 to 90% range of CPU
states, and works for maybe 3 or 4 seconds to return the querys. I am at
present doing this testing on a 550 mhz processor, but will be running
the ap on a dual 500s.

Am I getting totally out of hand in thinking I can do this?

Re: [PHP] Resource limit/performance questions

Well, then, assuming your complexity grows linearly, I guess you'll have
to wait a few minutes with 160,000 rows on which you can expect to
perform 16,000 queries...

You mention that you perform the queries on objects--can you elaborate
on this point?

Re: [PHP] Resource limit/performance questions

[Marco Tabini]

Well, the execution time depends on a number of factors. If your tables
are indexed properly and you take advantage of the indexes, then the
growth in execution time is not linear (I'm guessing the indexes are
maintained through balanced or semi-balanced trees or a similar method).
However, in your case, it's not the execution time but the number of
executions. Even under the best of circumstances, if the number of
queries increases in relation to the number of records, then you will
notice a proportional slowdown. If the queries do not use your indexes,
then the slowdown will probably be geometric, since the SQL engine will
have to spend more time sorting through the records for each query.

I usually say queries... it's worked so far :-)

I was wondering if this would grow linearly... as the data collects? So,
if it takes 3 seconds to do 2600 rows, will it take 30 seconds to do
26000 rows? I am using a simple for statement to send the 26 records
through the 10 querys.

A typical select is:

SELECT DISTINCT DATE_FORMAT(date, '%Y%m%d'), field2 FROM $table WHERE
field2 NOT LIKE '$anoption' AND field3 LIKE '$field2[$i]' AND
TO_DAYS(NOW()) - TO_DAYS(date) <= 30";

This select is run over with five different date <= numbers... then done
without the DISTINCT again over the same five time periods.

The array of records being sent through the 10 querys should not grow
too very large (26 in fact is a fairly high representation of what would
be average), whereas the number of records will grow at a fairly
predictable rate, with the same basic number of records added each day.

I should have said records, instead of objects. (too many sessions with
crAccess, too little time talking to real people about databases)

Now... would you spell that querys or queries?

Re: [PHP] Date Subtraction

[Marco Tabini]

I don't think you can use strtotime in that case. However, assuming that
your data is properly formatted every time, you can use a simple
function like this (I'm doing it from memory, so it might not actually
work):



Hope this helps.

I have two periods in time from a Cisco router that I would like to find the
difference in seconds. I am not sure the best way to do this since it is not
a date, but rather an amount of time since last reset.

Here is the numbers

181 days, 7:11:06.66
//stands for 181 days, 7 hours, 11 minutes, 6.66 seconds.

The next is

181 days, 7:16:6.75
//stands for 181 days, 7 hours, 16 minutes, 7.75 seconds.

I would probably shave off the .66 and .75 seconds while it was still a
string. It may be faster to round when it's in seconds, I really don't know.
Then what do I do?

I was thinking of using strtotime(); but because it's not really a date, I
am at a loss for what to do.

Any help with this would be great.

Re: [PHP] Does PHP recognize multiple selections in a form?

Hello Micah--

Yes, PHP supports multiple selections, but you need to change the name
of the control from submitID to submitID[], so that it will become an
array once inside your script.

I'm not sure how MySQL works under Windows, but you should either use
double backslashes (\\) instead of single backslashes or use forward

My guess is that your best bet is creating either an HTML or RTF

and it should be fairly easy to work with--you can save a template with
placeholders and simply replace them, since it's entirely text-based.

Hi all,

I have an update page that has a form in it.

However, I want to add another form in the same page.  My current form acts
upon itself (i.e. Action = the same page).  If I set up another form to do
the same, how would my PHP determine with action submit button was acted
upon?

Currently, for the single form here is how it knows a form was submitted:

if ((isset($HTTP_POST_VARS["MM_update"])) && ($HTTP_POST_VARS["MM_update"]
== "form1")) {

How would I test which form submitted the action?

Thanks and if I didn't make myself clear, I apologize.

Re: [PHP] call_user_method_array

[Marco Tabini]

Chris--

On my system, the function works as expected (at least as I understand
it): myFunc receives the parameters "Hello!" and array("this"=>"that"),
which is what you pass to it in the first place. Were you expecting it
to expand $myArrayVar into individual parameters? If so, that's not how
it works--it expands the values of the array you pass to it (which, in
this case, you build explicitly during the call), but doesn't expand any
arrays that may be within that array.

Also, call_user_method_array is now deprecated--you should use
call_user_func_array instead (the manual page for call_user_method_array
explains how to do this with a class method).

Cheers,

How does this function really work?  I've been
beating my head against the wall for the last
8 hours trying to figure it out.  This is what
I'm trying and it isn't working:
{this is a very simplified version}

class MyClass {
  function myFunc( $stringVar, $arrayVar ) {
echo "$stringVar\n";
echo "\n";
print_r( $arrayVar );
echo "\n";

  }
}

$myClass = new MyClass();

$myStringVar = "Hello!";
$myArrayVar  = array( "this" => "that" );

call_user_method_array( 'myFunc', 
&$myClass,
array( $myStringVar, $myArrayVar ));

What's happening is that the values in the array 
are not being passed individually but instead is
being passed as an array.  Shouldn't it be passing
them individually?  If not, it wouldn't seem as if
you could use this function generically.  You'd have
to specificy write your method so it can (possibly)
be called by this function.  And that just doesn't
seem right.

Any light anyone can shed on this would be very much
appreciated!!

Re: [PHP] No Idea - Comparing Lines

[Marco Tabini]

Hi Chris--

Try this:

 0)
{
$kbitsout = float) $data['OctetsOut'] - $olddata['OctetsOut']) /
($data['UnixTime'] - $olddata['UnixTime'])) * 8 ) / 1000;
print str_pad ($i, 2, ' ', STR_PAD_LEFT) . ' -- ' . number_format
($kbitsout, 2) . " kbits/s\n";
}

$olddata = $data;
$i++;
}

?>

I suggest you add some code to check for divisions by zero, depending on
whether your data requires it! 

Cheers,


Marco

Ok here is what I did but it does not do anything.
I verified that is opening the file ok and everything, but it shows nothing.
It doesn't even produce an error. I am sure there is an easier way than
looping twice, but this is how I have it for now.

$Lines = array();
$TempDir = "tempdata";
$DataFromFile = file("$TempDir/$Dat.txt");
while(list(,$oneline) = each($DataFromFile)) {
 array_push($Lines, $oneline);
 }
$LineCount = 1;
while(list(,$oneline) = each($DataFromFile)) {
  $PriorLineCount = $LineCount - 1;
  list($OctetsInB,$OctetsOutB,$TimeB) = split("|", $Lines[$LineCount]);
  list($OctetsInA,$OctetsOutA,$TimeA) = split("|", $Lines[$PriorLineCount]);
  // After much help and work with Harry, this is the formula we came up
with to show data rates over time.
  // (((Counter_Now - Counter_Before) / (Time_Now - Time_Before(converted to
seconds))) * 8)) / 1000 = kbits per hour
  $kbitsout = ((($OctetsOutB - $OctetsOutA) / ($TimeB - $TimeA)) * 8 ) /
1000;
  print "$kbitsout Kbits - $LineCount\n";
  $LineCount++;
 }

Re: [PHP] restrictions

Hello Bruce--

That depends on what restrictions are imposed on your box, of course.
Does your company use an SMTP-compatible mail server for your internal
mail? If so, you could use the server your mail client points to to
perform your tests.

I find that my the company that I work for is a little over protective.
My machine is quite restricted (as in firewall and accessability) when
it comes to ftp and telnet. Well basically my hands are tied in that
sense.
 
I am testing my database build on my local machine which runs fine and
all. I am curious though as to how these restrictions may affect my
attempts to send "mail()" I have tried various external SMTP srervers (i
am running off winxp pro) in my php.ini file and I get nothing. Just the
error code I have placed in (below).
 

 
Warning: Failed to connect to mailserver, verify your "SMTP" setting in
php.ini in c:\inetpub\wwwroot\_tasks\email.php on line 21
Mail could not be sent...
 
 
Would my local machines restrictions be stopping the mail function from
communicating with the SMTP server??
 
Cheers

Couple of suggestions:

1) Try connection to the SMTP server manually with Telnet, and see if
you discover more that way

2) Simply use the same SMTP server that is configured in your mail
client at work

It should say "port 25". If it's just a typo in your message, then it
could either be the restrictions or a general network problem--I know
this sounds stupid, but can you connect *at all* to anything else--ie. a

AFAIK, you should use a shared module when you're also using other
Apache modules that interface to MySQL. When you ./configure the PHP
interpreter, you get this info:

Hi Malcom--

Looks like you are outputting data right after your script starts (on
line to, you have an echo right away). You should either (a) turn on
output buffering, which should take care of the problem, or (b) (the
best solution because it makes your script behave the way it should)
move things around so that the decision on the redirect is made before
outputting anything. Try adding this at the beginning, before the echo:

if ($dog == 'mal')
header ('Location: ../aamaillist/ml_menu.php');


Hope this helps!

I guess the easiest would be to filter those images through a php
script. Your PHP script would perform whatever checks are needed (for
example, you could check ther HTTP_REFERER variable, or a shared token
with the originating PHP script) and then output the image only if it's
appropriate to do so. This way, your images would not be accessible to
your users at all--unless you wanted them to be.

Only if you let them. The PHP script allows to put the appropriate
checks in place. For example, if you use sessions, you can verify that
the session is still valid and that the user has, indeed, the right to
access that image. At a later time, even if another user types in the
same URL but does not have a valid session (or a variable inside the
session that contains the right data), you would be able to block him
from reading the image.

Cheers,


Marco

Yes--but you need to make the image inaccessible to the outside (simply
put them in a folder that can't be seen from the web).

Here's an example. Suppose you have a script called page.php that needs
an image called img.jpg. Instead of calling img.jpg, you call another
script, serveimage.php as follows:



Now, in serveimage.php you do this:



Essentially, what I'm doing is I'm replacing a file with a script that
first checks the permissions and then, if the user is authorized,
outputs the file to the browser. This way, if the user is not authorized
to download a file, it will be blocked. Obviously, the files themselves
should be inaccessible to the web *except* through your scripts.

Hope it's a bit clearer now!

Cheers,


Marco

Re: [PHP] IRR Function in PHP

[Marco Tabini]

If I may barge in...

The IRR represents the actual return of an investment over an arbitrary
period of time (usually annualized).

Say, for example, that you invest $100 and, after two years, you have
$120. Your overall return is 20%. If your interest rate was constant
over the two-year period and you never took any money out or put any
money in, your annualized IRR, that is the percentage that best
approximates how much you've made on a yearly basis, is approximately
9.544% and is calculated through the simple formula

IRR = (EndAmount / StartAmount) ^ (1 / NumberofPeriods) - 1.

IRR = (120 / 100) ^ (1 / 2) - 1 =~ 0.95445

If it sounds like a straightforward calculation... it isn't, because you
rarely have a clean-cut situation like that. Most of the time, you have
to deal with variations in the cash flows (interest payments,
reinvestments, disbursements, taxes, and so forth) and partial periods.

In some cases, the problem can only be solved by interpolation and the
calculation can become quite complex.

Cheers,


Marco

The browser *should* check but it doesn't. In fact, the limit that's
being exceeded is probably the one set in your php.ini configuration
file. In any case, it's generally a bad idea to trust the client with
performing any checks for anything other than the convenience of the
user, because it's very easy for a malicious user to send out a request
that contains completely arbitrary data ignoring completely all the
controls that are built into your HTML file.

Version 5 is still being actively developed (at least as far as I know),
so chances are that the release date is still a ways off. I've heard
anything from Q2-Q3 of 2003 on.

You can, however, download the current PHP5 CVS tree. I've been
experimenting with it and it's fairly stable--although I've seen some
messages that it leaks memory, for testing and learning how the new
stuff works it should be fine, IMO.

Out of curiosity, which feature were you interested in?

Re: [PHP] quick question

You should look at E-xact (http://www.e-xact.com). They have a solution
they call "tagged transactions" that actually replaces the credit card
numbers with "tags" that are only meaningful in the context of your
merchant account. That way, you can let your customers make repeat
purchases without actually having to store CC numbers on your site.

Re: [PHP] Problems compiling PHP 5.0.0b1

[Marco Tabini]

If you installed libxml2 from source--rather than from RPM--chances are
that it's been installed in a folder other than the system library
directory (/usr/lib). It's probably in /usr/local/lib instead. So you
can do one of two things: either reconfigure libxml2 specifying
--prefix=/usr or reconfigure PHP --with-libxml-dir= and your actual
libxml2 installation path.

Cheers,


Marco

Re: [PHP] Recommended package for online editing of HTML files

[Marco Tabini]

Hiya Brad--

We published a news item on this a few days ago; there's a free WYSIWYG
editor that works both on IE and Mozilla 1.3 called HTMLArea.

You can find it here:

http://www.interactivetools.com/products/htmlarea/reviews.html

(our news item is at http://phparch.com/newsarchive.php?s=htmlarea). I
use it in quite a few applications and it's both very useful and quite
stable.

Cheers,

Re: [PHP] Refreshing

[Marco Tabini]

Try using Javascript to reload an image instead of an HTML file. Images
don't click, and you can check whether new data is available by the size
of the returned image (e.g.: 1 pixel, no new data, 2pixels, new data).
You will need a small PHP script on the backend that generates the image
based on whether the data is available or not.

Cheers,


Marco

Set a timeout to x seconds (where x is the time you want to wait between
checks--say one or two seconds). When the timeout occurs cause the image
to reload by changing its src attribute (even to the same URL, of
course).

You don't need PHP to check the width of the image. PHP *generates* the
image of a given width based on whether new data is available or not. On
the frontend, you can set the onload event of the image to fire a
function of your choosing when the image is reloaded, where you check
its dimensions and act accordingly. Once you've done that, you reset
your timer, and the cycle starts over.

Cheers,


Marco

Re: [PHP] Refreshing

The image should take care of the click, and also reduce the amount of
information transmitted somewhat (although not necessarily, depending on
what you send to your iframe).

Re: [PHP] eregi_replace help

[Marco Tabini]

Jennifer--

A couple of things. eregi_replace does not have a limitation parameter,
which means that if you use it *all* the strings that match your pattern
will be replace with the new pattern. In your case, if I read your code
correctly (and I may not--I'm doing this from memory), the eregi
replacement you perform will change *all* the paths you have in your
file, and not just the first one, which, I believe, is what you're
looking for. 

Also, there shouldn't be any need to make the replacements one by one. A
single replacement should be enough if all the original paths have to be
transformed into the same URL.

For example:

ereg_replace ("{/images/}{test.(jpg|gif)}",
"http://www.microsoft.com/images/\\2";, $t);

This would replace any occurrence of "/images/*.gif" and "/images/*.jpg"
to "http://www.microsoft.com/images/*.gif"; or *.jpg respectively (once
again, double check my regex...doing this from memory). If you *do* need
to change each occurrence individually, then you should use preg()
instead, which uses Perl syntax and has a limitation parameter.

Also--a minor thing and I'm sure you thought of it, but you're not
saving the file at the end :-)

Hope this helps.

Cheers,


Marco

Re: [PHP] MAIL taking 60 seconds to send... (too long)

[Marco Tabini]

Hey John--

Couple of ideas:

1) Is your sendmail configured as a relay? As such your PHP process may
have to wait for the e-mail to be relayed before returning, which might
explain why it's taking so long. The same might happen if your machine
is very busy (although that has never happened to me)

2) Under IIS, you must configure a mail server in order for mail() to
work, because Windows does not have an MTA similar to sendmail installed
by default. You can do so in your php.ini file. Note that the MTA
doesn't have to be on a separate computer--if you use Windows SMTP and
configure it properly it should do just fine to use localhost as your
mail host.

Hope this helps.

Re: [PHP] parsing variables through webpages

[Marco Tabini]

You can use $_POST in a similar fashion to retrieve values from form
that have been posted with the POST method. 

Also, you can use $_REQUEST to catch both at the same time. In this
case, you may have a problem if the same variable is passed through both
GET and POST, in that one will override the other depending on how your
php.ini is set up.

Re: [PHP] Chat with php

[Marco Tabini]

Simple trick (well, not so simple, but kind of a Columbus' Egg):

1) Create an  tag in your web page that is hidden

2) Point the img tag to a php script that returns:

1) An image with a pixel width of 1 if there is new data to pick
   up from the server
2) An image with a pixel width of 0 otherwise

3) Create a javascript that refreshes the image every second (or every
two seconds, or however often you feel necessary--the more often, the
more responsive and "real time" your chat system will be).

4) Add an OnLoad event to the img tag that points to a Javascript that
checks the width of the newly reloaded image. If the width is one, then
you reload your chat text content (which you may want to put in an
iframe to avoid having to reload the whole page).

I don't have a script to show unfortunately, as it would probably be too
complicated and long for the list (and I have no time to write
it...), but hopefully, this will give you the gist of it.

Cheers,


Marco

Re: [PHP] Sockets

[Marco Tabini]

Yep, if you're using UNIX and compiling from source, you must add this
switch to the command line when you're configuring and compiling PHP:

 --enable-sockets

(e.g.: ./configure --enable-sockets). If you're using a prepackaged
version (RPM or Windows) then you should look into the documentation for
your version to see if this extension was included when the package was
compiled from the source.

Cheers,

Re: [PHP] Chat with php

[Marco Tabini]

Oliver--

I'm afraid I wasn't too clear! If you do it the way I'm suggesting, your
page will look like it's reloading ONLY when there is new data

Re: [PHP] Grabbing auto_increment during insert?

[Marco Tabini]

If you're using MySQL:

mysql_insert_id

If you're using MSSQL, you need to execute SELECT @@IDENTITY right after
your insertion operation. The result will give you the ID of your last
insertion. This won't work well if you're doing a bulk insert, though.

Re: [PHP] Deleting multiple items from database using checkboxes

[Marco Tabini]

Try WHERE EntryID IN (" . implode ($dele, ',') . ")"

However:

1) Anybody could fake a form post or query url to delete any data in
your database
2) It would also be possible to create a more dangerous post that could
give the attacker control over your entire database

Thus, I assume that you will want to put a *lot* of checking around that
code!

Unfortunately no, because the calculator is a Windows application that
runs on your local desktop and cannot be seen by your web-based users.

If you need your customers to use a calculator through their browsers,
you're probably looking for a Javascript calculator. Take a look at this
as an example:

Re: [PHP] PHP socket connections with SSL

[Marco Tabini]

Hi Darren--

4.3 is not out yet; the reference is to the current CVS version (which
will, eventually, become 4.3, I suppose), which you can check out and
use, although it is not an "official" release and will therefore
probably be a bit unstable (I've been running it on my dev server for a
while without much in the way of problems).

An alternative would be to compile the curl library in a 4.2 release and
use that one to pull SSL pages.

Re: [PHP] Encrypting passwords in a flat file before import

[Marco Tabini]

I think that generally you do not want passwords to be decryptable. What
I normally do is try to encrypt whatever the user enters as a password
and compare the resulting encrypted string with what's in the database
to make sure they correspond. If the encrypting function is univocal
(and md5 is) then the correct password will always return the same
encrypted string.

Re: [PHP] ASP Option Explicit equivalent in PHP

[Marco Tabini]

Well, you can set error_reporting to E_ALL, which will cause PHP to
complain if you use a variable without having it initialized. There is
no exact equivalent to Option Explicit--and there still isn't any need
to declare the variables, just to initialize them before use.

Re: [PHP] problem with SUM and Postgres

[Marco Tabini]

Because pg_exec only executes the query and returns the resource that's
associated with the returns. If you want to read the results, you should
use pg_fetch_result():

$sql1 = "SELECT SUM(hostingcost) FROM $tablename WHERE webserver =
'$webserver'";
$hosting_rs = pg_exec($connect, $sql1);
$hosting_data = pg_fetch_row ($hosting_rs, 0);
$hosting = $hosting_data[0];

Re: [PHP] Undefined variables?

[Marco Tabini]

Of course, you should switch to UNIX :-)

Seriously, have you looked at the source on those lines? Can you post
the source code otherwise so we can take a look and let you know?

The error you are receiving usually means that a variable is used
without having been initialized. For example:

$b = $a * 10;

Will cause a warning if $a is not set to something.

Re: [PHP] Undefined variables?

[Marco Tabini]

I think the problem is simply that the other server had a different
configuration setting for error reporting, since I can't find
$debug_wintrmte configured anywhere.

I don't know what this code is for, so it's difficult for me to say how
to fix it, since any changes I make may affect the outcome in a way that
will cause the system to stop working properly.

The only suggestion is to contact the original author or (if you are the
original author) to figure out how those variables should be managed. As
a last resort, and only if you are satisfied with the way the site works
right now (aside from the errors, of course), as James Hicks was
suggesting, you can just "hide" the errors by typing 

error_reporting(0);

Re: [PHP] MS SQL server TEXT column

[Marco Tabini]

Set TEXTSIZE usually does it for me:



Make sure that you select a database first and that the connection is
not closed between your Set TEXTSIZE op and the actual query. If you are
not specifying a connection in you mssql_query statement, make sure that
you haven't opened a different connection between Set TEXTSIZE and your
actual query--PHP uses the most recently opened connection as a default,
and if you open a new connection between the two queries, the second
connection will not have the TEXTSIZE set. Hope that helps.

This is actually a limitation of the sql libraries used by PHP (I assume

Select Cast(Field As Text) As Field

This should (and I say should because I can't test it right now :) take
care of the problem, although it might make your db a bit slower.

Re: [PHP] how to configure with ldap?

[Marco Tabini]

You need an LDAP package like OpenLDAP:

Re: [PHP] php cgi question

[Marco Tabini]

Without seeing your code... only one guess: what are the permissions on
the file like? When you're running the script from the web server,
you're running it as the user under which the web server is running
(usually nobody or apache if you're using Apache on Linux), and this
causes problem if that particular user doesn't have access to the file.

There are very few solutions to this problem (at least as far as I
know). One is the suexec module for Apache, that lets you impersonate
root or another user, but you have to be *extremely* careful with the
permissions. The other is to change the default permissions of the file
so that everyone can delete and modify it, but that might not work well
for your needs. Yet a third one would be to impersonate directly from
PHP, for example through a call to su, but there are pitfalls there as
well.

Hope this helps.

Re: [PHP] PHP/mySQL help or advice

[Marco Tabini]

There are a few PHP calendars:

http://www.cascade.org.uk/software/php/calendar/index.php

for example, that you can start from. It should be relatively easy then
to write a small table that contains just one field:

Date (datetime)

All you do is insert a row in the db for each day that is booked and
then whenever you have to check just hit the database: if there is a row
corresponding to the day you're checking, then the day is booked,
otherwise it isn't.

This is kind of the short version, but hopefully it should give you
enough to get going!

Cheers,


Marco
