GetOpt in 4.8.20 using each(), deprecated in PHP 7.2

[nebojsac]

Q	A
PHPUnit version	4.8.20
PHP version	7.2.8
Installation Method	Composer

Composer Info for the PHPUnit packages:

phpunit/php-code-coverage         2.2.4   Library that provides collection, processing, 
phpunit/php-file-iterator         1.4.5   FilterIterator implementation that filters 
phpunit/php-text-template         1.2.1   Simple template engine.
phpunit/php-timer                 1.0.9   Utility class for timing
phpunit/php-token-stream          1.4.12  Wrapper around PHP's tokenizer extension.
phpunit/phpunit                   4.8.36  The PHP Unit Testing framework.
phpunit/phpunit-mock-objects      2.3.8   Mock Object library for PHPUnit

We've switched from PHP 7.1 to PHP 7.2, which meant switching CakePHP from 2.9 to 2.10. Which in turn meant switching PHPUnit from 3.7.x to 4.8.x.

Now tests throw up warnings because each() is used in GetOpt.php:

Deprecated: The each() function is deprecated. This message will be suppressed on further calls in ./vendor/phpunit/phpunit/src/Util/Getopt.php on line 38

I get that this is an older version of PHPUnit, so I can work on this, if changes are still accepted for 4.x. I saw that GetOpt will be replaced at some point by Symfony, but even then probably not in this older version.

And thank you for the great work on PHPUnit!

EDIT: I guess I would just backport this one: #2536

Actually, just found out that CakePHP 2.10 supports PHPUnit 5.x as well, so no need for this change, in my case. Just needed to change the PHPUnit version in composer to 5.* and run composer update.
Hope this helps others.
