mcrypt_ecb — Deprecated: Encrypt/decrypt data in ECB mode
Description
string mcrypt_ecb
( int $cipher
, string $key
, string $data
, int $mode
)
string mcrypt_ecb
( 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.

There's a typo in this example. Replace MCRYPT_DECRUPT with MCRYPT_DECRYPT.
