I can't figure out how to get a url variable:

If I want to assign a variable with infomation passed with the url what array do I use to access this information?

"http://www.mysite.com/page.php?stuff=qwerty"

PHP Code:


<?php
$urlstuff = $_what goes_here;
?>

Thanks for any help,

Chip

The information passed in the URL is assigned as a variable:

On your example...

PHP Code:

<?php echo $stuff ?>

Would print..

qwerty

Talkupation apreciated :P

Lets say the URL is mysite.com/index.php?foo=bar
Then add a $ to foo so it is $foo.

PHP Code:

 <? echo"$foo"; ?>

It will display
bar

Understand?

Umm... both mad_willsy and Scout are correct, ONLY if you have register_globals set to on, which is a security risk.

Parameters passed in the URL are called GET parameters and are available through either the $_GET array or the $_REQUEST array.

In your case, you can do:
$urlstuff = $_GET['stuff'];

and then $urlstuff will be equal to 'qwerty'.

To add to what Scout said: you don't need to wrap a variable in quotes to print it and if you use single quotes, it won't 'interpret' the variable at all. So, again, in your case:

$urlstuff = $_GET['stuff'];
print "$urlstuff"; // prints qwerty
print $urlstuff; // also prints qwerty
print '$urlstuff'; // prints $urlstuff

$urlstuff = $_GET['stuff'];
and to get the the whole query string:
$_SERVER['QUERY_STRING']

Thanks All, TwistmyArm, it worked. I tried that before but couldn't get it to work. I had the syntax a lilttle incorrect. You set me straight. I appreciate the help.

I learned something from all the posts. Now I'm back on the straight and narrows...
