Class Finder Laravel Package

Could not locate PHP interrupter.

Example PHP:

<?php

require_once __DIR__ . '/../vendor/autoload.php';

use danog\ClassFinder\ClassFinder;

ClassFinder::enableExperimentalFilesSupport();
$classes = ClassFinder::getClassesInNamespace('Acme\Foo\Bar');

Results in this exception:

Could not locate PHP interrupter.

When running ClassFinder with support for autoloaded classes in files, ClassFinder must execute the included file in a shell to determine any defined classes in it. To do this, ClassFinder must determine the location of the PHP interrupter. If you're using PHP 5.4 or newer, PHP_BINARY should be set accurately and is used to determine the location of php. On PHP 5.3, ClassFinder attempts to find it via which (or where on Windows). If ClassFinder still can't find it, this exception is thrown.

Providing an explicit path to the PHP interrupter is not supported. Please open an issue that includes your use case, if you need this.

Possible Solution 1

Upgrade to a newer version of PHP that includes the PHP_BINARY constant.

Possible Solution 2

Add php to your $PATH so it can be discovered via which or where.
