PHP Code Sniffer VS PHP-CS-Fixer

PHP Insights supports sniffs from PHP CodeSniffer and fixers from PHP CS Fixer. This allows you to add any sniff or fixer as long as it implements PHP_CodeSniffer\Sniffs\Sniff or PhpCsFixer\Fixer\FixerInterface.

I don’t know why but that link keeps reloading the page over and over. This one works for me: https://github.com/squizlabs/PHP_CodeSniffer/issues/3932

PHP_CodeSniffer is a widely-used tool for enforcing coding standards in PHP. It checks the code against a set of predefined coding standards (such as PSR-12, PSR-2, and many others) and provides reports with violations and recommendations for improvement. Documentation: You can find more information about PHP_CodeSniffer and its usage in the official documentation: PHP_CodeSniffer Repository

While you're at it, also include code-style checkers like phpcs, phpmd and/or php-cs-fixer

If you are well-versed in programming then you might wanna take a look at PHPCompatibility. It will scan your codebase at different PHP version rulesets to point out code that needs upgrading. You will be needing PHPCS for this.

If you don't want to use any of those presets, your only option is to specify the all the rules by hand. Pint is built on top of PHP CS Fixer so you can use all the rules that it has. You can use the PHP-CS-Fixer configurator to cherry-pick your own set of rules.

1.1. Install the package php-cs-fixer

But I think in most cases they just mean follow the Coding Standard, Which still can be PSR-1, PSR-12 or the new PER Coding Standard. In this case I just recommend your company to add php-cs-fixer to the codebase to apply coding standards rules you want to follow. Good it it does not just lint it it will already fix it.
