note 51085 added to function.md5

If you are looking for other similar hashing functions, you can use the mhash lib: http://www.php.net/mhash. It includes around 25 hashing algorithms including MD5, MD4 and SHA1. Here's a little example of how to use mhash: <? $num_of_algs = mhash_count(); $string = "apples are nice"; for($i=0; $i<=$num_of_algs; $i++){ $name = @mhash_get_hash_name($i); $hash = @mhash($i, $string); # hash is in raw decimal form $hex = bin2hex($hash); # hex is in hexadecimal form echo "<p>Hashed with: ".$name."<br /><b>Binary:</b> ".$hash."<br /><b>Hexadecimal</b>: ".$hex."</p>"; } ?> @ used before function call incase a hash doesn't exist when it should. You can also use if($hash) echo "<p>... This will output both the raw binary output of each hash, and the hexadecimal output. You will notice that the hashing algorithm "WHIRLPOOL" has a very long length, so it might be a better choice over MD5. ---- Manual Page -- http://www.php.net/manual/en/function.md5.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+51085 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+51085&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+51085&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+51085&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+51085&report=yes&reason=useless Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+51085&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+51085&report=yes Search -- http://master.php.net/manage/user-notes.php
