Error Identifier: property.abstractWithoutAbstractHook

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 Shape
{
	abstract public string $name {
		get {
			return 'shape';
		}
		set;
	}
}

Why is it reported? #

The property is declared as abstract and has hooks, but none of its hooks are actually abstract (without a body). For a property to be declared abstract, it must specify at least one abstract hook – a hook declared without a body. If all hooks have bodies, the property is not abstract.

This is a PHP language-level restriction enforced since PHP 8.4 property hooks.

How to fix it #

Make at least one hook abstract by removing its body:

 abstract class Shape
 {
 	abstract public string $name {
-		get {
-			return 'shape';
-		}
+		get;
 		set;
 	}
 }

Alternatively, remove the abstract keyword from the property if all hooks should have implementations:

-abstract class Shape
+class Shape
 {
-	abstract public string $name {
+	public string $name {
 		get {
 			return 'shape';
 		}
+		set {
+			$this->name = $value;
+		}
 	}
 }

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.
