Itâ€™s not only insecure but it inconveniently commands the use of PHP function stripslashes() every time you pull something from the database or when you get something from the client side. While most of the hosts out there are using factory settings of PHP that turn off magic_quotes_gpc by default, there are a few that donâ€™t.
The value of magic_quotes_gpc cannot be set with the ini_set() function after PHP 4.2.3, some hosts enable custom php.ini in your home directory which you can use to set magic_quotes_gpc to 0 (zero) or false. Otherwise, youâ€™d have to resort to .htaccess to set the PHP configuration values for your local directories.
To turn off magic_quotes and magic_quotes_gpc off in .htaccess, simply put these lines in the .htaccess file of your site / directory wherein you want magic_quotes or magic_quotes_gpc disabled:
php_value magic_quotes 0 php_flag magic_quotes off php_value magic_quotes_gpc 0 php_flag magic_quotes_gpc off
