警告

此函数自 PHP 8.1.0 起弃用。强烈建议不要应用此特性。

说明

mhash(int $algo, string $data, ?string $key = null): string|false

mhash() applies a hash function specified by algo to the data.

参数

algo

The hash ID. One of the MHASH_hashname constants.

data

The user input, as a string.

key

If specified, the function will return the resulting HMAC instead. HMAC is keyed hashing for message authentication, or simply a message digest that depends on the specified key. Not all algorithms supported in mhash can be used in HMAC mode.

返回值

Returns the resulting hash (also called digest) or HMAC as a string, or false on error.
