note 18873 added to function.md5

The MD5 algorithm normally returns a 128-bit message-digest. The PHP md5-function returns a 32-character string, but the documentation doesn't say what algorithm is used to convert the 128-bit message-digest to a string. This may cause serious problems in the future of an applications life, since it's in the nature of a message-digest that it can't be converted to fit new conditions. -- http://www.php.net/manual/en/function.md5.php http://master.php.net/manage/user-notes.php?action=edit+18873 http://master.php.net/manage/user-notes.php?action=delete+18873 http://master.php.net/manage/user-notes.php?action=reject+18873
