Definition and Usage

The addslashes() function returns a string with backslashes in front of predefined characters.

The predefined characters are:

single quote (')double quote (")backslash (\)NULL

Tip: This function can be used to prepare a string for storage in a database and database queries.

Note: PHP runs addslashes() on all GET, POST, and COOKIE data by default. Therefore you should not use addslashes() on strings that have already been escaped, this will cause double escaping. The function get_magic_quotes_gpc() can be used to check this.
