    mhash — Computes hash

    Warning

    This function has been DEPRECATED as of PHP 8.1.0. Relying on this function is highly discouraged.

    Description

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

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

    Parameters

    algo

    The hash ID. One of the MHASH_hashname constants.

    data

    The user input, as a string.
