Question 1

How do I install PHP CS Fixer without Composer?

Accepted Answer

While Composer is recommended, the README mentions alternative methods like Docker or CI setups; refer to the installation instructions for details on other options, though they might involve more manual configuration.

Question 2

PHP CS Fixer vs PHP_CodeSniffer: which one should I use?

Accepted Answer

PHP CS Fixer is better for automated fixes, as it corrects issues on the fly, while PHP_CodeSniffer focuses on linting and reporting. Choose PHP CS Fixer if you want hands-off enforcement; PHP_CodeSniffer if you need detailed audits without automatic changes.

Question 3

How to configure PHP CS Fixer for a Symfony project?

Accepted Answer

Use the built-in @Symfony rule set in your configuration file; run `./vendor/bin/php-cs-fixer init` to create a base config, then modify it to include @Symfony for alignment with Symfony coding standards.

Question 4

Does PHP CS Fixer support PHP 8.4 or newer?

Accepted Answer

Support for the latest PHP versions may lag; check the README's supported versions list. If unsupported, you can use the `--allow-unsupported-php-version=yes` option, but this is not guaranteed to work correctly and should be used cautiously.

Question 5

How to create a custom rule in PHP CS Fixer?

Accepted Answer

Refer to the custom rules documentation; it involves writing PHP classes that extend base fixer classes, requiring a solid understanding of PHP and the tool's internals, which can be time-consuming for beginners.

Question 6

Can PHP CS Fixer fix all coding style issues automatically?

Accepted Answer

It covers most common issues with built-in rules, but for project-specific styles, you may need custom rules. It's highly effective for standard violations but might not address every edge case without additional configuration.
