New className call not working in php

I am trying to develop an php website using phpMyEdit , this is the link for the project. It was working until recently.

I updated my php to php7.0 then it stopped working. This is the issue.

// Now important call to phpMyEdit
require_once 'extensions/phpMyEdit-mce-cal.class.php';
new phpMyEdit_mce_cal($opts);

I have included the class file phpMyEdit-mce-cal.class.php till there it works. The new phpMyEdit_mce_cal($opts) doesnt work.

Is there some changes in the lastest version of php7.0 ?
