Ever since PHP turned register_globals_off I have had problems here and there in my codes. I searched hard and long for a simple fix while keeping globals turned off. Fortunately, I found one! I have posted it below for your convenience and it is also described Here.
I'm not sure if this has ever been posted, but if not I hope it helps you as much as it did me. :cool:
Here is the code to emulate register_globals On.
[CODE]
<?php
// Emulate register_globals on
if (!ini_get('register_globals')) {
$superglobals = array($_SERVER, $_ENV,
$_FILES, $_COOKIE, $_POST, $_GET);
if (isset($_SESSION)) {
array_unshift($superglobals, $_SESSION);
}
foreach ($superglobals as $superglobal) {
extract($superglobal, EXTR_SKIP);
}
ini_set('register_globals', true);
}
?> [/CODE]
And this code will emulate register_globals Off.
[CODE]
<?php
// Emulate register_globals off
if (ini_get('register_globals')) {
$superglobals = array($_SERVER, $_ENV,
$_FILES, $_COOKIE, $_POST, $_GET);
if (isset($_SESSION)) {
array_unshift($superglobals, $_SESSION);
}
foreach ($superglobals as $superglobal) {
foreach ($superglobal as $global => $value) {
unset($GLOBALS[$global]);
}
}
ini_set('register_globals', false);
}
?>
[/CODE]
To emulate register_globals = on one could just use
<?php extract($_REQUEST); ?>and, register_globals = off is not being emulated the right way in your snippet.
I use this snippet in all my codes if I have problems postings or getting vars. It works every time for me. I have made this into a class and used it for a long time.
Now why do you say :
and, register_globals = off is not being emulated the right way in your snippet.
Some people may use $_REQUEST in their codes which is fine, but as long as you code with security in mind and you know where the vars and methods are coming from $_REQUEST does not need to be used.
