Pls update to php 7.1

There seem to be differences between php 7.0. and 7.1
Example:

This is no longer allowed in php 7.1.7 while it is allowed in php 7.0.25:

<?php
$var = '';
$var['name'] = 'Joe';

It has been proven that it should be in php 7.1.7:

<?php
$var = array();
$var['name'] = 'Joe';

Please update this plugin so it signals this type of errors.
There may be more locations in my plugins where i did this…

Thanx in advance
