Question

There is a function in Mysql AES_encrypt.

SELECT AES_encrypt( \"Hello World\", \"password\" ) AS encrypted_value 

This gives the result:

Answer 1

The MySQL AES_encrypt uses a 128-bit key length - Reference here

Whereas your PHP code uses 256-bit key lengths.

To fix the problem you should be able to uses 'MCRYPT_RIJNDAEL_128' instead of 256.
