property.neverRead

Code example

<?php declare(strict_types = 1);

class Foo
{
	private ?string $name {
		get => $this->items[$this->index] ?? null;
	}

	/** @var string[] */
	public array $items = [];

	private int $index = 0;

	public function setIndex(int $i): void
	{
		$this->index = $i;
	}
}

Why is it reported?

The property is readable (has a get hook) but is never actually read anywhere in the code. This indicates dead code -- a property that provides a read interface but has no consumers. Since the property is private, it can only be accessed within the class, and PHPStan has verified it is never read there.

How to fix it

Remove the property if it is no longer needed:

 class Foo
 {
-	private ?string $name {
-		get => $this->items[$this->index] ?? null;
-	}
-
 	/** @var string[] */
 	public array $items = [];

 	private int $index = 0;
 }

Alternatively, if the property should be read, add the missing read access in the class.
