 * Using a php compatibility checker, I get these warnings:
 * Extension ‘mysql_’ is deprecated since PHP 5.5 and removed since PHP 7.0; Use
   mysqli instead
 * I know the code uses this with caution, but maybe it is time to remove the old
   code 🙂

 * Please take a look through existing support threads and take a look at the code
   in question. This gets reported numerous times. The code is perfectly compatible
   with PHP 7.

 * Yes, I know it is compatible, but maybe it is just time to remove unused calls
   that are deprecated since 5.5 now …
    But I do understand it is not causing issues,
   it would just clean up compatibility check results.

 * But break support for people still using old PHP versions.
 * Perhaps don’t rely on compatibility checkers if you don’t know how to interpret
   results that don’t matter for you.

 * Wow … where is this hostility coming from? I was just reporting on some php thing,
   not asking to be personally attacked. Before you start assuming things about 
   a person, first investigate on them … I’ve been around from before php was there,
   have been called a linux expert on more than one occasion and even teached php
   courses, so I think I can interpret things just fine.
    Anyway, if you think you
   should still support old php versions that went EOL years ago and at the same
   time start attacking people just politely reporting it, feel free to do so. I
   will still give your plugin high rates, although not thanks to your “friendly”
   replies.
