Script mysql.inc.php is not compatible with PHP 5

[JirkaW]

Script adminer\drivers\mysql.inc.php uses null coalescing operator (??) on lines 1095 and 1101 (add in PHP 7.0).

Hmm, it is getting more and more difficult to support so old version of PHP.
https://www.php.net/supported-versions.php
PHP 5.x is even not on the supported versions of PHP, even not in end of life.

I see EOL dates at https://www.php.net/eol.php

The most recent date I see here for PHP 5.x is for 5.6.40 EOL on 31 Dec 2018 (or 10 Jan 2019), not quite 5 years ago.

I don't see any value continuing to support PHP 5.x. If someone wants that, they can always use adminer.

I agree with dropped php5 support.
