Why not to use Magic Quotes
Warning This feature has been DEPRECATED as of PHP 5.3.0 and REMOVED as of PHP 5.4.0.
- Portability Assuming it to be on, or off, affects portability. Use get_magic_quotes_gpc() to check for this, and code accordingly.
- Performance Because not every piece of escaped data is inserted into a database, there is a performance loss for escaping all this data. Simply calling on the escaping functions (like addslashes()) at runtime is more efficient. Although
php.ini-development
enables these directives by default,php.ini-production
disables it. This recommendation is mainly due to performance reasons. - Inconvenience Because not all data needs escaping, it's often annoying to see escaped data where it shouldn't be. For example, emailing from a form, and seeing a bunch of \' within the email. To fix, this may require excessive use of stripslashes().
