Error Identifier: method.static

Every error reported by PHPStan has an error identifier. Here’s a list of all error identifiers. In PHPStan Pro you can see the error identifier next to each error and filter errors by their identifiers.

Code example #

<?php declare(strict_types = 1);

class ParentClass
{
	public function doFoo(): void
	{
	}
}

class ChildClass extends ParentClass
{
	public static function doFoo(): void
	{
	}
}

Why is it reported? #

A static method overrides a non-static method from a parent class. PHP does not allow changing a non-static method to static in a child class. This will cause a fatal error at runtime.

How to fix it #

Keep the method non-static in the child class:

 <?php declare(strict_types = 1);
 
 class ChildClass extends ParentClass
 {
-	public static function doFoo(): void
+	public function doFoo(): void
 	{
 	}
 }

Non-ignorable error #

This error cannot be ignored using @phpstan-ignore or the ignoreErrors configuration. Non-ignorable errors indicate code that would cause a crash or a fatal error at runtime, or a fundamental problem in the analysed code that must be addressed.
