If you get this error after upgrading to PHP 7 0  then you are using deprecated libraries       mysql connect     Open a connection to a MySQL Server   Warning    This   extension was deprecated in PHP 5 5 0  and it was removed in PHP   7 0 0  Instead  the MySQLi or PDO MySQL extension should be used    More here  http   php net manual en function mysql-connect php
