wordpress magic quotes by php code

I have wordpress installation where the magic quotes is set ON in the phpini file. this cause that every quote is duplicated every time I update a post.

I can't change the phpini is out of my capability, so the only way is by php code.

the parameter in my wp-config.php file is set with magic quote to 0.

Someone know where I add some code to perform it.

I use the custom post so I need of a solution with this compatible.

thanks in advance.

at the end I have found this:

if ( get_magic_quotes_gpc() ) {
    $_POST      = array_map( 'stripslashes_deep', $_POST );
    $_GET       = array_map( 'stripslashes_deep', $_GET );
    $_COOKIE    = array_map( 'stripslashes_deep', $_COOKIE );
    $_REQUEST   = array_map( 'stripslashes_deep', $_REQUEST ); 
}

to set at the begin of my page.

and it works.

thanks to all.
