hash - Generate a hash value (message digest)
hash(
string$algo,
string$data,
[bool$binary = false],
[array$options = []] ): string
Parameters
- algo
-
Name of selected hashing algorithm (i.e. "md5", "sha256", "haval160,4", etc..). For a list of supported algorithms see hash_algos.
- data
-
Message to be hashed.
- binary
-
When set to true, outputs raw binary data. false outputs lowercase hexits.
- options
-
An array of options for the various hashing algorithms. Currently, only the "seed" parameter is supported by the MurmurHash variants.
Return Values
Returns a string containing the calculated message digest as lowercase hexits unless binary is set to true in which case the raw binary representation of the message digest is returned.
