My friend asked me how to run PHP scripts (which is written for register global = on environment) in a register global = off environment. Yeah, it’s a bad thing to write PHP script for register global = on environment, he just wanted his old scripts work with minimum efforts.

So I gave him a short script, which will regenerate variables from $_POST or $_GET. This script need to be placed onto the top of every single file which required variable from POST or GET method.

< ?php foreach($_POST as $key=>$value){
$$key = $value;
}
foreach($_GET as $key=>$value){
$$key = $value;
}
?>

Above script will, for example, generate variable named $username from $_POST[‘username’] with the same value.

Just remember to put above script in the top of your scripts, and remember NOT to write bad scripts.
