Re: [PHP] $HTTP_GET_VARS within a function ??
http://localhost/test.php?var=5
results in (global scope)
$var = 5; // Register globals on
$HTTP_GET_VARS['var'] = 5; // Always (?)
$_GET['var'] = 5; // With newer versions of PHP
To access this from a function:
function x() {
global $var;
globsl $HTTP_GET_VARS;
echo $var.'BR';
echo $HTTP_GET_VARS['var'].'BR';
echo $_GET['var'].'BR';
}
Note, that there is no global $_GET; - $_GET is a superglobal. That means,
you can always access it.

Re: [PHP] $HTTP_GET_VARS within a function ??
Try using global $HTTP_GET_VARS; at the beginning of your function. $HTTP_GET_VARS has global scope, and by default PHP isolates functions from the parent scope.

It seem I could only access that array if I pass it as a parameter of the function. Is this how it's supposed to work. Thanks for any direction. NOTE: I am using PHP 4.0.6.
