PHP mhash_get_block_size() Function

The mhash_get_block_size() function is an inbuilt function in PHP which is used to gets the block size of the specified hash. Gets the highest available hash ID within the current MHash installed in the system like SHA1, MD%, etc.

Syntax:

int mhash_get_block_size( int $hash )

Parameter: This function accepts one parameter as shown in the above syntax. The parameters are described below:

• $Hash: The hash ID. One of the MHASH_hashname constants.

Return Value: This function returns the hash name and it’s block size which contains the list of supported hashing algorithms.

Example: Below program illustrates the mhash_get_block_size() function in PHP.

PHP

<?php

$maxHashCount = mhash_count();

for ($hashNumber = 0; $hashNumber <=
        $maxHashCount; $hashNumber++) {

    // i-th hash name
    $hashName = mhash_get_hash_name($hashNumber);

    // i-th block size
    $hashSize = mhash_get_block_size($hashNumber);

    // Details of i-th hash
    print_r($hashName . " 's block size is"
                . $hashSize . "\n");
}
?>

Output:
