Error Identifier: property.abstractNonHooked
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);
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:
abstract class Person
{
- abstract public string $name;
+ abstract public string $name { get; set; }
}
Or remove the abstract modifier and use a regular property:
abstract class Person
{
- abstract public string $name;
+ public string $name;
}
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.
