constructor.missingParentCall

Code example

<?php declare(strict_types = 1);

class ParentClass
{
	public function __construct()
	{
		// initialization logic
	}
}

class ChildClass extends ParentClass
{
	public function __construct(private string $name)
	{
		// missing parent::__construct() call
	}
}

Why is it reported?

This rule is part of phpstan-strict-rules.

A child class defines its own constructor but does not call the parent class's constructor. When a parent class has a constructor with initialization logic, failing to call it from the child constructor can leave the object in an inconsistent or uninitialized state.

In the example above, ChildClass::__construct() does not call parent::__construct(), so the initialization logic in ParentClass is skipped.

How to fix it

Call the parent constructor from the child constructor:

 <?php declare(strict_types = 1);

 class ChildClass extends ParentClass
 {
 	public function __construct(private string $name)
 	{
-		// missing parent::__construct() call
+		parent::__construct();
 	}
 }
