addslashes() function PHP


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

The predefined characters are:

  • single quote (‘)
  • double quote (“)
  • backslash (\)
  • NULL



Parameter Values

string : Defines the string to be escaped.

Technical Details

Return Value : Returns the escaped string.

PHP Version : 4+


<?php $string = addcslashes('Codeamend "Community" Team');

Output : Codeamend \"Community\" Team 


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

Prior to PHP 5.4, the PHP dir magic_quotes_gpc was on by default and it ran addslashes() on all GET, POST, and COOKIE data by default. You should not use addslashes() on strings that have already been escaped, as it will cause double escaping. The function get_magic_quotes_gpc() can be used to check this.
