Unfortunately magic_quotes_gpc can not be changed at run-time, but here's a code block which
will effectively get rid of it when executed. Use this for PHP scripts which must be portable or
run on servers where magic_quotes_gpc could be configured either way.
Note that the PHP help is a little misleading... Magic_quotes_gpc affects more than just the Get,
Post, and Cookie data!
<?php
//Prevent Magic Quotes from affecting scripts, regardless of server settings
//Make sure when reading file data,
//PHP doesn't "magically" mangle backslashes!
set_magic_quotes_runtime(FALSE);
if (get_magic_quotes_gpc()) {
/*
All these global variables are slash-encoded by default,
because magic_quotes_gpc is set by default!
(And magic_quotes_gpc affects more than just $_GET, $_POST, and $_COOKIE)
*/
$_SERVER = stripslashes_array($_SERVER);
$_GET = stripslashes_array($_GET);
$_POST = stripslashes_array($_POST);
$_COOKIE = stripslashes_array($_COOKIE);

}
/*
The $GLOBALS array is also slash-encoded, but when all the above are
changed, $GLOBALS is updated to reflect those changes. (Therefore
$GLOBALS should never be modified directly). $GLOBALS also contains
infinite recursion, so it's dangerous...
