PHPStan webmozart/assert extension

• PHPStan
• webmozart/assert

Description

The main scope of this extension is to help phpstan to detect the type of object after the Webmozart\Assert validation.

<?php declare(strict_types = 1);

use Webmozart\Assert;

function demo(?int $a) {
	// ...

	Assert::integer($a);
	// phpstan is now aware that $a can no longer be `null` at this point

	return ($a === 10);
}

This extension specifies types of values passed to:

• Assert::integer
• Assert::positiveInteger
• Assert::string
• Assert::stringNotEmpty
• Assert::float
• Assert::numeric
• Assert::natural
• Assert::integerish
• Assert::boolean
• Assert::scalar
• Assert::object
• Assert::resource
• Assert::isCallable
• Assert::isArray
• Assert::isTraversable (deprecated, use isIterable or isInstanceOf instead)
• Assert::isIterable
• Assert::isCountable
• Assert::isInstanceOf
• Assert::isInstanceOfAny
• Assert::notInstanceOf
• Assert::isAOf
• Assert::isAnyOf
• Assert::isNotA
• Assert::subclassOf
• Assert::true
• Assert::false
• Assert::notFalse
• Assert::null
