require.fileNotFound

Code example

<?php declare(strict_types = 1);

require 'a-file-that-does-not-exist.php';

Why is it reported?

The path passed to require() resolves to a file that does not exist on disk. At runtime, require will produce a fatal error when the file cannot be found. PHPStan checks the path against the current working directory, the PHP include path, and the directory of the analysed file.

How to fix it

Correct the file path:

-require 'a-file-that-does-not-exist.php';
+require __DIR__ . '/existing-file.php';

Or ensure the file exists at the expected location. When paths are computed dynamically, PHPStan can only check constant string paths.
