Find Optimized-Away Lines (FOAL)

foal finds lines of code that are eliminated by OpCache's bytecode optimizer.

Installation

PHP Archive (PHAR)

The easiest way to obtain foalis to download a PHP Archive (PHAR) that has all required dependencies bundled in a single file:

$ wget https://phar.phpunit.de/foal.phar

Composer

You can add this tool as a local, per-project, development-time dependency to your project using Composer:

$ composer require --dev sebastian/foal

You can then invoke it using the ./vendor/bin/foal executable.

Usage

example.php

<?php
function f()
{
    $result = 'result';

    return $result;
}
$ php foal.phar example.php
foal 1.0.0 by Sebastian Bergmann.

The OpCache optimizer eliminated the following sourcecode lines:

4          $result = 'result';
7      }
