The length of returned string might be different according to the O.S. Incompatibility might be not because of the version of PHP but because of the change of O.S. The old source was running on Redhat 6.x, and I executed it today on Redhat 7.x. Crypt("") function seems to depend on the O.S. Anyway, this means crypt() is not compatible between O.S. and this means crypt() is not recommened. -- http://www.php.net/manual/en/function.crypt.php http://master.php.net/manage/user-notes.php?action=edit+20655 http://master.php.net/manage/user-notes.php?action=delete+20655 http://master.php.net/manage/user-notes.php?action=reject+20655
