Update pagex.class.php

Fix deprecated dynamic property creation and week calculation in relativeTime function

- Resolved deprecated warning by avoiding dynamic property creation on DateInterval object.
- Calculated weeks separately and included them correctly in the output string.
- Adjusted the logic to handle weeks within the string array without creating a dynamic property.
- Ensured compatibility with PHP 8.2 and higher, where dynamic properties are deprecated.

This fix prevents the "Deprecated: Creation of dynamic property DateInterval::$w is deprecated" warning and correctly formats the relative time string.
