addslashes - Quote string with slashes

addslashes( string$string ): string

Returns a string with backslashes added before characters that need to be escaped. These characters are: single quote (') double quote (") backslash (\) NUL (the NUL byte)

A use case of addslashes is escaping the aforementioned characters in a string that is to be evaluated by PHP:

"echo '" addslashes($str) . "';");

The addslashes is sometimes incorrectly used to try to prevent SQL Injection. Instead, database-specific escaping functions and/or prepared statements should be used.
