hi,

$_GET doesn't have a value as it's an array, but if you wanted to access each index in the array, you'd probably need something like:

foreach($_GET as $k => $v) {
  $k = $v;
}

otherwise you need something like ${$_GET["variable"]} = "blah"; i'm not sure if that's what you're after though

Thank you very much


i was confused with the information posted ont he PHP site:
Please note that variable variables cannot be used with PHP's Superglobal arrays. This means you cannot do things like ${$_GET}.
