Php Arguments Detector Laravel Package
degraciamathieu/php-arguments-detector
Detect and analyze function/method arguments in PHP using a lightweight, reflection-based approach. Useful for tooling that needs to inspect call signatures, validate inputs, or generate metadata about parameters and defaults across codebases.
php arguments detector
The ideal number of arguments for a function is zero. ~ Robert C. Martin
Keep control over the complexity of your methods by checking that they do not have too many arguments with this package.

Requires >= PHP 7.3
composer require degraciamathieu/php-arguments-detector --dev

vendor/bin/phpargsdetector inspect {folder}

Weight
The weight is the number of arguments multiplied by the number of lines of the method.
The weight of the foo method is 10 : 2 arguments * 5 lines.
class Bar {
public function foo($a, $b)
{
if ($a) {
//
}
return $b;
}
}
You can use it as a complexity indicator.
