@requires function swallows digits at the end of function name

[MaxSem]

Q	A
PHPUnit version	7.5.1
PHP version	7.2.13
Installation Method	PHAR

If a required function name ends with a digit, PHPUnit misses the digit(s).

Example:

<?php
/**
 * @requires function hash_pbkdf2
 */
class DummyTest extends PHPUnit\Framework\TestCase {
}

Current behavior:

$ php phpunit-7.5.1.phar --verbose test.php
PHPUnit 7.5.1 by Sebastian Bergmann and contributors.

Runtime:       PHP 7.2.13

S                                                                   1 / 1 (100%)

Time: 84 ms, Memory: 10.00MB

There was 1 skipped test:

1) Warning
Function hash_pbkdf is required.

OK, but incomplete, skipped, or risky tests!
Tests: 1, Assertions: 0, Skipped: 1.

Expected behavior: test is not skipped because hash_pbkdf2() is present.

@MaxSem Thanks for taking the time to submit the issue! I have reproduced it in the self-test collection and... fireworks! A solid start to 2019, I say. Will submit a pull request with a fix.

I will also check whether the other @requires parameters like setting and extension suffer from the same bug:

Aha, seems the regex eats the trailing digit as a part of a version requirement. I'll have to do some exploring to make sure a fix for this doesn't break a bunch of other use cases.

@MaxSem PHPUnit 6.5.14 has just been released and I noticed the Mediawiki composer.json picking it up as expected:

Again thanks for reporting the bug, it has been fixed in v7 and v8 too :)
