Microsoft Word - Core PHP Programming Using PHP to Build Dynamic Web Sites

The metaphone algorithm, invented by Lawrence Philips, was first described in
Computer Language magazine. You may find a discussion of metaphone at Scott Gasch's
Algorithm Archive http://perl.guru.org/alg/node131.html.

string mhash(integer hash, string data)

Use mhash to get a hash for a string. Hashing algorithms available at the time of writing
are shown in Table 9.2.

Refer to the Mhash documentation for more information about each algorithm.

<?
print(mhash(MHASH_GOST, "Who is John Galt?"));
?>

integer mhash_count()

The mhash_count function returns the highest-numbered hash identifier. All hash
algorithms are numbered from zero, so you can use this function and
mhash_get_hash_name to get a complete list.
