property.abstractInInterface

Code example

<?php declare(strict_types = 1);

interface HasName
{
	abstract public string $name { get; } // ERROR: Property in interface cannot be explicitly abstract.
}

Why is it reported?

Properties declared in interfaces are implicitly abstract, similar to how interface methods are implicitly abstract. Adding the abstract keyword explicitly is redundant and not allowed by PHP. All interface properties with hooks are already required to be implemented by classes that implement the interface.

How to fix it

Remove the abstract keyword from the property declaration:

 <?php declare(strict_types = 1);

 interface HasName
 {
-	abstract public string $name { get; }
+	public string $name { get; }
 }
