        hash_hmac ( string $algo , string $data , string $key [, bool $raw_output = FALSE ] ) : string
algo
Name of selected hashing algorithm (i.e. "md5", "sha256", "haval160,4", etc..) See hash_hmac_algos() for a list of supported algorithms.

data
Message to be hashed.

key
Shared secret key used for generating the HMAC variant of the message digest.

raw_output
When set to TRUE, outputs raw binary data. FALSE outputs lowercase hexits.
