property.abstractNonHooked - Phpstan

Code example

php

<?php declare(strict_types = 1);

abstract class Person
{
	abstract public string $name;
}

Why is it reported?

In PHP 8.4+, only hooked properties can be declared abstract. A property without hooks has no behaviour that subclasses need to implement, so making it abstract does not make sense. PHP rejects this at compile time.

How to fix it

Add hooks to the property to make it abstract:

diff-php

 abstract class Person
 {
-	abstract public string $name;
+	abstract public string $name { get; set; }
 }

Or remove the abstract modifier and use a regular property:

diff-php

 abstract class Person
 {
-	abstract public string $name;
+	public string $name;
 }
