outOfClass.static

Code example

<?php declare(strict_types = 1);

$value = static::FOO;

Why is it reported?

The static keyword is being used to access a class constant (or in a class-name context) outside of a class scope. The static keyword in this context refers to the class the method was called on (late static binding), but it is only meaningful inside a class method. Using it outside of a class results in a fatal error at runtime.

How to fix it

Use the actual class name instead of static, or move the code inside a class method.

 <?php declare(strict_types = 1);

-$value = static::FOO;
+$value = MyClass::FOO;

Or move the code inside a class:

 <?php declare(strict_types = 1);

 class MyClass
 {
 	public const FOO = 'bar';

 	public function getValue(): string
 	{
 		return static::FOO;
 	}
 }
