While "global variables are good" in quotes did not return any results
from Google, "global variables are evil" in quotes only returned a result
set of 4:

Results *1* - *4* of *4* for *" 
global
variableare
evil
"*
**
Hardly an overwhelming argument by using search results as a measure.

David




Nevermind. I forgot the 's'.

Once again:

Personalized Results *1* - *8* of *8* for
*"global
variablesare
good
"*. (*0.17* seconds)

Personalized Results *1* - *10* of about *136* for
*"global
variablesare
evil
"*. (*0.07* seconds

Ok. So those of us who use globals are 17 time more likely to end up in
hell.

I can live with those odds.

1. your problem description is pretty useless - apart form being seemingly
incoherent you also mention an 'if block' and an 'else block' in such a way as
to imply that there is only one of each (there are plenty of each in the code 
provided).

2. your code is not properly indented at all which makes reading it
and trying to figure out what it does (and what it is supposed to do)
too much bother.

3. your doing alsorts of things wrong aside from any flawed logic that
the script apparently contains.

e.g.

1. why set the following session value unconditionally each time?
why not just use the POST value?

$_SESSION['voucher_value'] =  $_POST['voucher_to'];


2. I assume that k1 is not a constant you have defined elsewhere...

if($_SESSION['voucher_value'] == k1)


3. you have big SQL injection holes in the script, also you make blind
assumptions about incoming request data:

I have never seen this problem effect just one browser on on platform -
afaic it's a general problem that effects all browsers - you can't send
out HTTP headers after HTTP content ... now it maybe that some browsers
these days see fit to ignore white space before the headers (or maybe
just ignore a "\n") but I doubt it ... honestly I can't see how php
would even send the headers after the "\n" had been output ... either
you error logging level is too low, your not reading the error log or you
have error suppression on the header() function (.e.g @header()). all
of these would give you the incorrect notion that the header function

Re: [PHP] uh oh, I defined a resoruce

[Nathan Nobbe]

the 2 problems that globals introduce are

   1. namespace collisions
   2. point of origin problem

where a  namespace collision is the inconsistent use of a global
variable within an application
eg.
// one point in the application
$GLOBALS['curUser'] = array('username' => 'bob', 'userId' => 5);

// another point in the application
$GLOBALS['curUser'] = new stdClass();
$GLOBALS['curUser']->username = 'bob';
$GLOBALS['curUser']->userId = 5;

and what im calling the 'point of origin' problem, is the ambiguity
introduced by global variables.  when reading through the code of an
application and you encounter the use of a global variable, where was
that variable set?  if not in the same file, then youll have to start
looking.  you may not even be able to determine where the value is
getting set by looking through the code, that is, you might have to analyze
the runtime behavior of the application.  and with the $GLOBALS array, this
can be cumbersome because there is no way (that i know of) to add implicit
logging to setting of values within.

now, whether you or your team or business or w/e will have to deal with
these
problems depends on what sort of conventions, if any, are used to work with
globals (or whether theyre used at all ;)).

to make them work in a team environment you should have some external
documentation
that establishes clear usage guidelines and outlines the purpose (or
declares 'namespaces')
within the $GLOBALS array.  so you might say "$GLOBALS['user'] is designated
to contain
user data, which will be a record from the users table in our database".  it
will be an array.
at that point if someone uses $GLOBALS['user'] for something else, or
changes its data type
or something, you can say, well youve violated our convention here so youll
have to clean that up.

there is the issue of working with code from other parties and this is where
things
can still get messy.  say that you have your conventions and everything is
hunky-dory; then you
decide to use some third party code, and it uses one of your global
'namespaces'.
so for example you get some third party code and within it, for whatever
reason $GLOBALS['user']
(referenced earlier) is being read or set.  well if you want to use that
code, youll have to refactor
either yours, or theirs.

object oriented development helps with some of these problems, but it is not
by itself a silver bullet.
for example with singleton
http://www.phppatterns.com/doku.php/design/singleton_pattern
problems 1, and 2 above are still relevant.  php is introducing namespaces
soon enough, but prior
to those class name collisions are generally resolved in php by prefixing a
class name
eg.
class User {}
becomes
class MyBiz__User {}

problem 2 though is relevant depending on what the singleton is used for.
suppose it only contains
2 values, a reference to itself and one datum, which is set in the private
constructor (or another private
method invoked as part of the constructor).  this is the most trivial case
and it is not really subject to
the problem.  however, if a singleton were to have getter and setter methods
problem number 2 above
can occur.  the good news here is that since singleton is a class you write,
adding logging is trivial
so you should be able to track down those spurious cases where a value is
set in one portion of the
application and read in another.

i happen to know that facebook uses globals, and i just thought i would
mention it as a 'successful'
yet perhaps 'code not so great' example of a large application using
globals.

if you are to use globals, then establish conventions.
the worst stuff i have ever seen is use of other superglobal arrays for the
same purpose as what the
$GLOBALS array is intended to be.
eg.
// one part of the application
// NOTE: this value did not orginate from the request
$_POST['someVal'] = 5;

// later in the application
$myVar = $_POST['someVal'];

that is just plain bad if you ask me (and they didnt even put the note!).

A very cogent and detailed assessment of the issues, Nathan, and I
appreciate the time and thoughtfulness involved in writing your response.

My stance concerning globals is that, on PHP projects anyway, I work alone,
use longish and very descriptive variable names, and most always only use
globals for static data needed for calculations of some kind. But I
certainly appreciate that in a team environment and when working on very
large projects, the odds of globals usage, especially without documentation
and adherence to a standard, can lead to the problems described above.

In general, I agree with Stut's response delineated earlier in this thread,
that a careful and circumscribed use of globals has a place in PHP
programming.

[PHP] var_dump() results

[Europus]

It's pretty much the same. With var_dump(), values from the first row
of the table are iterated twice, the script is not looping through and
reporting all 2100 rows. Grossly similar behavior was observed with
print_r() and echo: while different data was reported by each, the
loop wouldn't loop. The first row was reported once (or twice) and
that was the end of that. I've tried foreach() also, same-same. It
doesn't loop, it just reports the first row.

Here's my code:

";

This was coming from common c and c++ practice. In this enviroments using

and uh oh, that php thing was using share nothing perspective. No race

From my point of view. After 8 years of php programming only one time face the

Of course your millage was vary...

It doesn't loop through all rows because you use mysql_fetch_row. Wich 
does exactly
what it's name tells you. It fetches one single row. So instead of 
looping through the
whole result set. You are looping through every cell off the result set. 
You're probably

better of using mysql_fetch_array().

As far as displaying only the first row, that's because you're only 
fetching the first row; count($row) in your for loop will always 
evaluate to 0 (if there are no results) or 1. You need to move the 
mysql_fetch_row() call into your loop; something like


$result = mysql_query($sql);
while ($row = mysql_fetch_row($result)) {
var_dump($row);
...
}

or you could do

$result = mysql_query($sql);
$count = mysql_num_rows($result);
for ($i=0; $i<$count; $i++) {
var_dump($row);
...
}

As far as displaying the results twice, I'm not sure; that resembles 
the behavior of mysql_fetch_array() -


http://us.php.net/manual/en/function.mysql-fetch-array.php

- where the default is to return data as both an associative and 
numerically-indexed array. I'm guessing that the above code isn't an 
exact cut-and-paste, as using single quotes (eg, 
mysql_pconnect('$host', '$login', '$passwd') does not interpolate 
variables, so that line will not work unless your username is 
actually '$login', etc. Which it probably isn't. Are you sure the 
real code isn't using mysql_fetch_array() instead of 
mysql_fetch_row()?

Yes well looking at the starting code i realise i forgot something. 
Sorry for that.

When doing mysql_fetch_array or mysql_fetch_row you get only one row.
So what you want to do is loop through the result set:

$result = mysql_query($sql);

//loop through to display results
while ($row = mysql_fetch_array($result)) {
   var_dump($row);
   echo "";
}

P.s. Please reply to the list also :)

I didn't want to reveal the real names of my server/host, table,
login or password to the list, so I tried setting $host, $login,
$passwd, and $table variables at the top of the script. That way
it's 4 lines to omit when posting code, instead of parsing through
to edit each instance. That didn't work so I've since restored the
initial values, probably I stepped on a reserved word. I'll check
on that, I like the idea of setting those to variables elsewhere.


//get column data
$sql= "SELECT column2, column3 FROM $table";
$result = mysql_query($sql);


if (!$result) {
echo "query failed.\n";

$row = mysql_fetch_row($result);


Now that, that change makes what looks to be 2100 rows of data flood
the screen, thank you. Now I can move on to processing that data
in the next step of my script.

It looks like, my take-away lesson is that I was invoking var_dump()
too late, I should have been performing that check right after running
mysql_fetch_array(), because later operations step on the data and
that's why I was getting unexpected returns.

Noted, thank you. I'll play with these too, to see what I think of them.

behavior of mysql_fetch_array() -


The script had ~fetch_array() initially, I couldn't get it to work as
expected so I changed it to ~fetch_row(). Now it's back to ~fetch_array()

Both as a learning exercise and as an end-goal, I'm rewriting some
code so that it does what I want it to, not what it imperfectly does
according to the original programmers intent. That original intent
bears only passing resemblance to what was requested of that programmer,
it's become a sore subject.


http://us.php.net/manual/en/function.mysql-fetch-array.php

- where the default is to return data as both an associative and 
numerically-indexed array. 


That explains some things. And I have some reading and experimenting
to do before I move on to the next step in the script.

I'm guessing that the above code isn't an 
exact cut-and-paste, as using single quotes (eg, mysql_pconnect('$host', 
'$login', '$passwd') does not interpolate variables, so that line will 
not work unless your username is actually '$login', etc. Which it 
probably isn't. 


Correct. That was my attempt to obfuscate some of my real data, the
username and password especially. See my other post on this.

[PHP] DESC order results

[Danny Brow]

Just wondering if anyone could tell me how reliable the DESC order
option is going to be when I am parsing thousands of records where they
are multiple ChartNo's for the same clientNo. Or is there a better way
to grab the most recent ChartNo.

$link = mysql_connect('localhost', 'myuser', 'mypassword') or die('Could
not connect: ' . mysql());

mysql_select_db('mydatabase') or die('Could not select database');

$query = 'SELECT * FROM eChart WHERE clientNo = "2" ORDER BY ChartNo
DESC';

$result = mysql_query($query) or die('Query failed: ' . mysql_error());

$line = mysql_fetch_array($result, MYSQL_ASSOC);


// Just for testing
print mysql_num_rows($result);



Thanks,
Dan

this is a mysql question not a php question, please try to ask questions
in the appropriate forum.

the reliability of 'ORDER BY' is not tied to the ammount of
records returned.

given that you only want the 'most recent'
(by which I assume you mean the 'highest value') ChartNo for
a given clientNo you should be performing a query that returns a
single row of data.

also you shouldn't be quoting values pertaining to numeric fields
(I assume clientNo is an integer)

1. assuming ChartNo is numeric:

SELECT MAX(ChartNo) as chartno FROM eChart WHERE clientNo=2

2. assuming ChartNo is a varchar (or similar):

SELECT ChartNo FROM eChart WHERE clientNo=2 ORDER BY ChartNo DESC LIMIT 0,1



$link = mysql_connect('localhost', 'myuser', 'mypassword') or die('Could
not connect: ' . mysql());

mysql_select_db('mydatabase') or die('Could not select database');

$query = 'SELECT * FROM eChart WHERE clientNo = "2" ORDER BY ChartNo
DESC';

$result = mysql_query($query) or die('Query failed: ' . mysql_error());

$line = mysql_fetch_array($result, MYSQL_ASSOC);

no race conditions occur in code written in php? true that there is
no direct race conditions that can occur as a direct result of running code
but obviously you've never dealt with multi-user systems using a databse

or file-writing based tools used in a web-environment (e.g. template output 
caching)

I think you just made up 'variable crashing' - at any rate it not a concept
I understand to mean anything specific to the issue we are talking about.



From my point of view. After 8 years of php programming only one time face the

well that seals it then - obviously globals are fantastic?!?

You can use the MIME parser package. It can be used to parse whole
messages including extracting e-mail addresses from the headers.

But if you have already the From address header value, you can use the
RFC822 address parser class which can extract the e-mail addresses and
any names associated to the names.

It also has some tolerance to malformed addresses, so it can parse
addresses in messages that are not correctly formatted according to the
e-mail standards.

Take a look in particular at the test_message_decoder.php and
test_parse_addresses.php example scripts.

Good... that will be my answer next time I don't have anything to say on a

And yeah... you can search for "Free PHP " and you'll get some
Ad-Oriented websites if you know what I mean... sometimes Google just sucks.

And sometimes "Yes, once I used  which is reliable, simple and supports
German..." is not that hard to answer. If for every issue you come across
you have to use Google alone, then get rid of the list... there were so many
jerky questions that got answered here... Anyway, I'll just have to write my
own and save it on our library, there's a German speaking woman in the
company which will give me a hand. I personally hate guestbooks, but I

This list is "about" php, ie what you build ... lets say guestbooks of. Jerky 
or not, this is where you come when you hit a brickwall, with no lazyness

Did you do any research before askin' for help? sure didn't sound like it.
Remember that some (most?) of these guys (and gals?) do php for a living, and 
take it out of their own pocket trying to help one'another, and it's a rude 
practice demanding without showing you'd done some forehand homework.
Me? I'm just rude enought to point that out.

I hope you catch on to both my irony and what I try to tell you, if so you'd 
be doin' just fine

[PHP] $_GET and multiple spaces.

[Churchill, Craig]

Hello,

One of the values I'm passing in a URL string contains multiple spaces.

...
(The multiple spaces are between Argononemertes and australiensis)

However when I retrieve the value using $_GET[DarScientificName]
there is only a single space between the two names which I understand is the 
intended behaviour?

Is there a way to preserve the multiple spaces?

Thanks
Craig.

It's very difficult to recommend "the best" book to learn from (although 
I'm tempted to suggest my own). Different people learn in different 
ways. Also, people want to use PHP in different ways, not to mention the 
fact that you don't say what your current skill level is.


My advice would be to go to Amazon, and browse the books on PHP. Read 
the reviews. See which are the best sellers.


I have a lot of PHP books on my shelf. The two that are the most 
well-thumbed as "PHP Programming" by Rasmus Lerdorf and Kevin Tatroe, 
and "Upgrading to PHP 5" by Adam Trachtenberg.


The book by Matt Zandstra that you mention is very good, but it's very 
specialized. If you're already at an intermediate-advanced level, and 
want to learn about design patterns with PHP, it might be a good choice. 
If you're at a less advanced level, maybe not.

[PHP] Re: $_GET and multiple spaces.

[Al]

Try "%20" for each space. Better yet, use underscores "_"

Hmmm interesting so you mean 

$GLOBALS['language'] = memcached->get('language');

race condition prone  than

function hede() {
global $language

$language = memcached->get('language');

}

Re: [PHP] var_dump() results

[Chris]

or you could do

$result = mysql_query($sql);
$count = mysql_num_rows($result);
for ($i=0; $i<$count; $i++) {
var_dump($row);
...
}


Not unless you have a

$row = mysql_fetch_assoc($result);

before doing the var_dump of $row because $row isn't being set :)

side note: where does $table come from?


I didn't want to reveal the real names of my server/host, table,
login or password to the list, so I tried setting $host, $login,
$passwd, and $table variables at the top of the script. That way
it's 4 lines to omit when posting code, instead of parsing through
to edit each instance. That didn't work so I've since restored the
initial values, probably I stepped on a reserved word. I'll check
on that, I like the idea of setting those to variables elsewhere.


The reason your variables didn't work was that you had them enclosed in 
single quotes.  Within single quotes, no variables are parsed.  Two 
options to fix this.  Use double quotes, or get rid of the quotes 
completely since you are using variables.  The latter suggestion is 
probably the most preferred way of working with variables.


here is the code from your original email.  I have modified it to work 
like one would expect it too.


'.print_r($row, 1);
}

?>

Give this a try and see what happens.  Should do everything you want it 
to do and maybe more.


Jim




//get column data
$sql= "SELECT column2, column3 FROM $table";
$result = mysql_query($sql);


if (!$result) {
echo "query failed.\n";
} else {
while ($row = mysql_fetch_array($result))
var_dump($row);
}  


$row = mysql_fetch_row($result);


Now that, that change makes what looks to be 2100 rows of data flood
the screen, thank you. Now I can move on to processing that data
in the next step of my script.

It looks like, my take-away lesson is that I was invoking var_dump()
too late, I should have been performing that check right after running
mysql_fetch_array(), because later operations step on the data and
that's why I was getting unexpected returns.
