Thanks for the amazing plugin. It works pretty great. Just noticed an error looks like due to PHP 7.2 differences.

Environment
Osclass 3.8.0
PHP 7.2

Noticed these errors in the error log
[19-Jan-2019 11:18:51 America/New_York] PHP Warning:  count(): Parameter must be an array or an object that implements Countable in /oc-content/plugins/minify/functions.php on line 213

Looks like this is related to this the count() function see link below.

Figured i'd shared so this can be updated in future to ensure maximum compatibility for those using PHP 7.2.x

Thanks for feedback, you can put @ sign before count to disable notices for this function.
