PHPUnit 8.5 incompatibility with PHP 8.1

[nikic]

Q	A
PHPUnit version	8.5
PHP version	8.1-dev
Installation Method	Composer

Summary

phpunit/src/Util/Configuration.php

Line 443 in 957aaf3

$target = &$GLOBALS;

throws a compile-time error as a result of https://wiki.php.net/rfc/restrict_globals_usage. This issue only exists in PHPUnit 8 and lower, not in PHPUnit 9.

If I understand the purpose of the code right, I think this would be a good way to fix the issue:

foreach ($configuration[$array] as $name => $data) {
    $GLOBALS[$name] = $data['value'];
    $_SERVER[$name] = $data['value'];
    $_POST[$name] = $data['value'];
    $_GET[$name] = $data['value'];
    $_REQUEST[$name] = $data['value'];
    $_COOKIE[$name] = $data['value'];
    $_FILES[$name] = $data['value'];
}

In this case the code that tries to abstract over the different arrays makes things more complicated than just directly assigning all of them, due to the special cases that need to be handled.

Thank you for bringing this to my attention, I will work on this as soon as possible.
