note 15397 added to function.md5

It should be noted that PHP's MD5 implementation gives you a 256 bit hash (32 characters long), while the "RSA Data Security Inc. MD5 Message-Digest Algorithm" provides a 128 bit hash (16 characters long) instead. You can check that out by reading the RFC1321 docs in the very link they included in the MD5 function's description. That means saying it's "using" RSA's standard MD5 is slightly misleading. You can say it's "based on" the standard, but it's a non-standard implementation. Dan 'Neurobasher' Gomes http://www.php.net/manual/en/function.md5.php
