Why Are My $_POST Variables Escaped on Production but Not Locally?

Why Escaped POST Variables on Production Server

When receiving data from AJAX POST requests, if your $_POST variables are being escaped on your production server but not on your local server, a probable cause is enabled magic quotes on the production server.

Magic quotes automatically escape single-quote, double-quote, backslash, and null characters when they are part of data received from external sources like POST requests. This feature is a security measure to prevent malicious code injection, but it can also cause problems when you need to retrieve the raw data.

To resolve the issue and ensure consistent behavior across both servers, you have a few options:

Disable Magic Quotes

The recommended approach is to disable magic quotes in php.ini. This globally disables the escaping of POST variables. However, it's important to note that magic quotes will be removed in PHP 6, so it's a good idea to avoid relying on them.

Strip Slashes

If you cannot disable magic quotes, you can manually strip the slashes from the $_POST variables using the stripslashes() function:

if (get_magic_quotes_gpc()) {
    $my_post_var = stripslashes($_POST["my_post_var"]);
}

By implementing one of these solutions, you can ensure that the $_POST variables are not getting escaped on your production server and that both your local and production servers behave consistently.
