staticMethod.deprecatedInterface - Phpstan

Code example

php

<?php declare(strict_types = 1);

/** @deprecated Use NewFactory instead */
interface OldFactory
{
	public static function create(): object;
}

class MyFactory implements OldFactory
{
	public static function create(): object
	{
		return new \stdClass();
	}
}

function doFoo(): void
{
	OldFactory::create();
}

Why is it reported?

This error is reported by the phpstan-deprecation-rules extension.

A static method is being called on an interface that is marked as @deprecated. Deprecated interfaces are scheduled for removal or replacement. Calling static methods on them ties the code to an API that will eventually be removed.

How to fix it

Use the recommended replacement interface or class instead:

diff-php

 <?php declare(strict_types = 1);

 function doFoo(): void
 {
-	OldFactory::create();
+	NewFactory::create();
 }

If the calling code is itself deprecated, the error will not be reported. Mark the function or class as deprecated if it is part of a deprecation migration:

diff-php

 <?php declare(strict_types = 1);

+/** @deprecated */
 function doFoo(): void
 {
 	OldFactory::create();
 }
