Error Identifier: property.nonStatic

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 Base
{
	public static string $name = 'base';
}

class Child extends Base
{
	public string $name = 'child';
}

Why is it reported? #

A non-static property in a child class overrides a static property in the parent class. PHP does not allow changing the static/non-static nature of a property during inheritance. This causes a fatal error at runtime.

How to fix it #

Match the parent property’s static modifier:

 class Child extends Base
 {
-	public string $name = 'child';
+	public static string $name = 'child';
 }

Or redesign the class hierarchy so the property does not conflict:

 class Child extends Base
 {
-	public string $name = 'child';
+	public string $childName = 'child';
 }

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.
