List of PHP Kata to Update

PHP 8.0 with PHPUnit 9.5.2 was added. The kata on this page needs to be updated manually. Any help is appreciated!

Summary of Changes

• Files are no longer concatenated, but it should work very similarly as before because solution and preloaded files are autoloaded
• The name of the test class now required to end with Test
• Solution and Preloaded file should have <?php
  • Runner prepends this if missing for backwards compatibility, but any new code should include it
• Test file should have <?php use PHPUnit\Framework\TestCase;
  • Runner prepends this if <?php is missing for backwards compatibility, but any new code should include it
• PHPUnit is updated to 9.5.2 so there are some breaking changes
