If you are using the variable $username as a variable variable type thing..
like you don't know what username is going to be each time...
Use double quotes:
$_GET["$username"];
that will make PHP interpolate the variable and use whatever value $username
is as the name of the $_GET var. Single quotes ''' tells PHP 'take the
$tring as is and don't interpolate anything'
you HAVE to do that.. you can't do... if you have the register_globals
directive on for example ${$username}.. no no no. Doesn't like that.
double quotes say "interpolate $variables". However I have discovered (at
least in php 4.2.3) that you cannot use subarrays in double quotes like "my
var in the subarray subarray: $array['subarray']['subarray']" That doesn't
seem to work.. it comes up blank.

Subject: [PHP] Pulling variables from a URL
I have a URL including variables... It looks like this:
http://registration.php?username=111111&[EMAIL PROTECTED]
But I can't pullit into the next page's form
Here is what is in the form and other things I have tried:
$username = $_HTTP_POST_VARS['username'];
echo $_GET['$username'];
echo $_POST['$username'];
This page sumbits with PHP_SELF if that helps with this puzzle.
Can someone tell me what I'm doing wrong?
Also I do have an include file that looks for session
information but Ihave disabled it to see if I can pass
variables.
Frank
