I think the post below is useless here..
magic_quotes_runtime is not magic_quotes_gpc.. when magic_quotes_runtime is enabled (on, =1, true), then every function call working with some kind of database will return strings with slashes (like addslashes everytime you call such a function). magic_quotes_gpc instead is what is meant in the post below - and in fact, magic_quotes_runtime does not do anything to it. but if there existed some function like set_magic_quotes_gpc it would not do anything too, the reason is mentioned below..
so if you're searchin' for a way to turn off quotes_gpc than set the directive in the INI-File or with the help of the php_value-flag of mod_php, when php is compiled as an apache module, inside of an .htaccess-file (PERDIR-configuration). otherwise you really have to check wether quotes_gpc is enabled or not and than add addslashes or stripslashes as you need on the input-variables.
and as mentioned in the post below that one belows this one ( -.- ) magic_quotes_runtime is mostrly useless too..
