note 25252 added to function.md5

Oh, this is an odd problem: I have a password [md5(serialize($userpass)] which I insert into a mysql-table. When I log in to my site via a form, I do the following: onsubmit: $userpass=md5(serialize($userpass)); SELECT userid, username, userpass FROM tbluser; Then I compare both strings, and it always says "Wrong password". I found out, that the hash inserted into the table is completely different from the one I generate in the script. What am I doing wrong? -- http://www.php.net/manual/en/function.md5.php http://master.php.net/manage/user-notes.php?action=edit+25252 http://master.php.net/manage/user-notes.php?action=delete+25252 http://master.php.net/manage/user-notes.php?action=reject+25252
