What's in this repo ? --------------------- [](#whats-in-this-repo-) A ruleset for PHP\_CodeSniffer to check for PHP cross-version compatibility issues in projects, while accounting for polyfills provided by [@ircmaxell](https://github.com/ircmaxell/)'s [password\_compat](https://github.com/ircmaxell/password_compat) polyfill library. This ruleset prevents false positives from the [PHPCompatibility standard](https://github.com/PHPCompatibility/PHPCompatibility) by excluding back-fills and polyfills which are provided by the `password_compat` library. Funding ------- [](#funding) **This project needs funding.** The project team has spend thousands of hours creating and maintaining the PHPCompatibility packages. This is unsustainable without funding. If you use PHPCompatibility, please fund this work by setting up a monthly contribution to the [PHP\_CodeSniffer Open Collective](https://opencollective.com/php_codesniffer). Requirements ------------ [](#requirements) - PHP > 5.4 - [PHP\_CodeSniffer](https://github.com/PHPCSStandards/PHP_CodeSniffer) >= 3.13.3. Use the latest stable release of PHP\_CodeSniffer for the best results. - [PHPCompatibility](https://github.com/PHPCompatibility/PHPCompatibility) 10.0.0+. Installation instructions ------------------------- [](#installation-instructions) The only supported installation method is via [Composer](https://getcomposer.org/). [Composer](https://getcomposer.org/) will automatically install the project dependencies and register the external rulesets with PHP\_CodeSniffer using the [Composer PHPCS plugin](https://github.com/PHPCSStandards/composer-installer/). Run the following from the root of your project: ``` composer config allow-plugins.dealerdirect/phpcodesniffer-composer-installer true composer require --dev phpcompatibility/phpcompatibility-passwordcompat:"^2.0@dev" ``` Next, run: ``` vendor/bin/phpcs -i ``` If all went well, you will now see that the `PHPCompatibility` and `PHPCompatibilityPasswordCompat` standards are installed for PHP\_CodeSniffer. Upgrade instructions -------------------- [](#upgrade-instructions) To upgrade this package, run the following command: ``` composer update --dev phpcompatibility/phpcompatibility-passwordcompat --with-dependencies ``` Tip If you have a *root* requirement in your project for one of the packages used by this project, you may need to update with `--with-all-dependencies` instead. How to use ---------- [](#how-to-use) You can now use the following command to inspect the code in your project for PHP cross-version compatibility: ``` vendor/bin/phpcs -p . --standard=PHPCompatibilityPasswordCompat ``` By default, you will only receive notifications about deprecated and/or removed PHP features. To get the most out of the PHPCompatibilityPasswordCompat standard, you should specify a `testVersion` to check against. That will enable the checks for both deprecated/removed PHP features as well as the detection of code using new PHP features. For example: ``` # For a project which should be compatible with PHP 5.3 up to and including PHP 7.0: vendor/bin/phpcs -p . --standard=PHPCompatibilityPasswordCompat --runtime-set testVersion 5.3-7.0 # For a project which should be compatible with PHP 5.4 and higher: vendor/bin/phpcs -p . --standard=PHPCompatibilityPasswordCompat --runtime-set testVersion 5.4- ``` For more detailed information about setting the `testVersion`, see the README of the generic [PHPCompatibility](https://github.com/PHPCompatibility/PHPCompatibility#sniffing-your-code-for-compatibility-with-specific-php-versions) standard. ### Testing PHP files only [](#testing-php-files-only) By default PHP\_CodeSniffer < 4.0 will analyse PHP, JavaScript and CSS files. As the PHPCompatibility sniffs only target PHP code, you can make the run slightly faster by telling PHP\_CodeSniffer to only check PHP files, like so: ``` vendor/bin/phpcs -p . --standard=PHPCompatibilityPasswordCompat --extensions=php --runtime-set testVersion 5.3- ``` License ------- [](#license) All code within the PHPCompatibility organisation is released under the GNU Lesser General Public License (LGPL).
