Flattr this git repo Build Status Latest Stable Version Latest Unstable Version License

This is a set of sniffs for PHP_CodeSniffer that checks for PHP version compatibility.

Installation

  • Install PHP_CodeSniffer with pear install PHP_CodeSniffer (PHP_CodeSniffer 1.5.1 or later is required for full support, notices may be thrown on older versions).
  • Checkout this repository as PHPCompatibility into the PHP/CodeSniffer/Standards directory.
  • Use the coding standard with phpcs --standard=PHPCompatibility
  • You can specify which PHP version you want to test against by specifying --runtime-set testVersion 5.5.

More information can be found on Wim Godden's blog.

Running the Sniff Tests

All the sniffs are fully tested with PHPUnit tests. In order to run the tests on the sniffs, the following installation steps are required.

  1. Install the master branch of PHP_CodeSniffer [https://github.com/squizlabs/PHP_CodeSniffer.git].

    This can be done with composer by adding the following into ~/.composer/composer.json:

    {
        "require": {
            "phpunit/phpunit": "3.7.*",
            "squizlabs/php_codesniffer": "dev-master"
        }
    }
    
  2. Run the following command to compose in the versions indicated in the above global composer.json file:

    $ composer.phar global install
    
  3. Update your system $PATH to include the globally composed files:

    $ export PATH=~/.composer/vendor/bin:$PATH
    
  4. Be sure that the PHPCompatibility directory is symlinked into PHP_Codesniffer's standards directory:

    $ ln -s /path/to/PHPCompatibility ~/.composer/vendor/squizlabs/php_codesniffer/CodeSniffer/Standards/PHPCompatibility
    
  5. Verify standard is available with phpcs -i. The output should include PHPCompatibility

  6. Run the tests by running phpunit in the root directory of PHPCompatibility. It will read the phpunit.xml file and execute the tests
