note 101846 added to function.crypt

In PHP 5.3.1, I am running into trouble with crypt() and numeric strings: code: $salt = '$1$abcdefgh$'; $pass = "123"; $pass2 = "123a"; echo crypt($pass, $salt)."<br />\n"; echo crypt($pass, $salt)."<br />\n"; echo crypt($pass2, $salt)."<br />\n"; echo crypt($pass2, $salt)."<br />\n"; output: $1$abcdefgh$OTo2MhKVLtpE9bkEycLQf0 $1$abcdefgh$JwVLNLvq4bwIKuyv1qm8L0 $1$abcdefgh$PiPnB9KJsYjPIXtoia0WK/ $1$abcdefgh$PiPnB9KJsYjPIXtoia0WK/ the results of the alphanumeric string are expected, but the numeric only string returns a different result each time crypt() is called. I am at a loss. ---- Server IP: 69.147.83.197 Probable Submitter: 12.146.200.2 ---- Manual Page -- http://www.php.net/manual/en/function.crypt.php Edit -- https://master.php.net/note/edit/101846 Del: integrated -- https://master.php.net/note/delete/101846/integrated Del: useless -- https://master.php.net/note/delete/101846/useless Del: bad code -- https://master.php.net/note/delete/101846/bad+code Del: spam -- https://master.php.net/note/delete/101846/spam Del: non-english -- https://master.php.net/note/delete/101846/non-english Del: in docs -- https://master.php.net/note/delete/101846/in+docs Del: other reasons-- https://master.php.net/note/delete/101846 Reject -- https://master.php.net/note/reject/101846 Search -- https://master.php.net/manage/user-notes.php
