addslashes

Definition and usage

addslashes() function returns a string that adds a backslash before the predefined characters.

The predefined characters are:

• Single quotes (')
• Double quotes (")
• Backslash (\)
• NULL

Tip: This function can be used to prepare strings for strings stored in the database and database query statements.

Note: By default, PHP automatically runs addslashes() on all GET, POST, and COOKIE data. So you should not use addslashes() for escaped strings, as this will result in double-layer escape. In this case, you can use the function get_magic_quotes_gpc() to detect it.
