However, if you do use exclude directives for PHPCompatibility sniffs in a custom ruleset or if you use the new-style PHP_CodeSniffer inline annotations, you will need to update these when upgrading. If you use the complete PHPCompatibility standard without exclude directives in a custom ruleset and do not (yet) use the new-style PHP_CodeSniffer annotation as introduced in PHP_CodeSniffer 3.2.0, this will have no noticeable effect and everything should work as before. All sniffs have been placed in categories and a significant number of sniffs have been renamed. ⚠️ Upgrading to PHPCompatibility 9.0.0 ⚠️ Thanks to WP Engine for their support on the PHP 7.0 sniffs. Thanks to all contributors for their valuable contributions. While the sniffs will still work in most cases, you can expect PHP warnings to be thrown.įor running the sniffs on PHP 7.4, it is recommended to use PHP_CodeSniffer 3.5.0+ for the same reasons.Īs of version 8.0.0, the PHPCompatibility standard can also be used with PHP CodeSniffer 3.x.Īs of version 9.0.0, support for PHP CodeSniffer 1.5.x and low 2.x versions < 2.3.0 has been dropped.Īs of version 10.0.0, support for PHP < 5.4 and PHP CodeSniffer < 2.6.0 has been dropped.

The sniffs are designed to give the same results regardless of which PHP version you are using to run PHP CodeSniffer. However, coverage for changes introduced before PHP 5.1 will remain patchy as sniffs for this are not actively being developed at this time. Pull requests that check for compatibility issues in PHP 4 code - in particular between PHP 4 and PHP 5.0 - are very welcome as there are still situations where people need help upgrading legacy systems.
Progress is tracked on our GitHub issue tracker. This is an ongoing process and coverage is not yet 100% (if, indeed, it ever could be).
