Download the PHP package phpcompatibility/phpcompatibility-all without Composer

PHPCompatibilityAll

Convenience package to install all the external PHP_CodeSniffer rulesets which the PHPCompatibility organisation maintains, in one go using Composer.

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.

Installation instructions

The only supported installation method is via Composer.

Composer will automatically install the project dependencies and register the external rulesets with PHP_CodeSniffer using the Composer PHPCS plugin.

Run the following from the root of your project:

Next, run:

If all went well, you will now see that the PHPCompatibility, PHPCompatibilityJoomla, PHPCompatibilityWP and a number of polyfill related standards are installed for PHP_CodeSniffer.

Upgrade instructions

To upgrade this package, run the following command:

[!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

You can now use any of the following commands to inspect your code:

By default, you will only receive notifications about deprecated and/or removed PHP features.

To get the most out of the PHPCompatibility standards, 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.

• You can run the checks for just one specific PHP version by adding --runtime-set testVersion 5.5 to your command line command.
• You can also specify a range of PHP versions that your code needs to support. In this situation, compatibility issues that affect any of the PHP versions in that range will be reported: --runtime-set testVersion 5.3-5.5.
• Since PHPCompatibility 7.1.3, you can omit one part of the range if you want to support everything above or below a particular version, i.e. use --runtime-set testVersion 7.0- to run all the checks for PHP 7.0 and above.

For example:

For more detailed information, see the README of the main PHPCompatibility standard.

Testing PHP files only

By default PHP_CodeSniffer 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:
