Compatible with php 7+ ?

Hi again,

Here are results from WP Engines compatibility check:

ERROR | ‘resource’ is a reserved keyword as of PHP version 7.0 and cannot be used to name a class, interface or trait or as part of a namespace (T_NAMESPACE)

ERROR | Function split() is deprecated since PHP 5.3 and removed since PHP 7.0; use preg_split instead

Thanks!
