string hash_hmac ( string $algo , string $data , string $key [, bool $raw_output = FALSE ] )
Parameters ::
Name of selected hashing algorithm (i.e. “md5”, “sha256”, “haval160,4”, etc..) See hash_hmac_algos() for a list of supported algorithms.
Message to be hashed.
Shared secret key used for generating the HMAC variant of the message digest.
When set to TRUE, outputs raw binary data. FALSE outputs lowercase hexits.
Return Values ::
Returns a string containing the calculated message digest as lowercase hexits unless raw_output is set to true in which case the raw binary representation of the message digest is returned. Returns FALSE when algo is unknown.
