int mhash_count();mhash_count() returns the highest available hash id. Hashes are numbered from 0 to this hash id.
Example 1. Traversing all hashes <?php
$nr = mhash_count();
for($i = 0; $i <= $nr; $i++) {
echo sprintf("The blocksize of %s is %d\n",
mhash_get_hash_name($i),
mhash_get_block_size($i));
}
?>
