mcrypt_cbc — Encrypt/decrypt data in CBC mode

### Description

string mcrypt_cbc ( string `$cipher` , string `$key` , string `$data` , int `$mode` [, string `$iv` ] )

The first prototype is when linked against libmcrypt 2.2.x, the second when linked against libmcrypt 2.4.x or higher. The `mode` should be either `MCRYPT_ENCRYPT` or `MCRYPT_DECRYPT`.

This function should not be used anymore, see mcrypt_generic() and mdecrypt_generic() for replacements.
