Find PHP Executable in Symfony 7

When working with a Symfony application, there are times when we may need to run an external PHP script. However, to achieve this, it's crucial to be aware of the PHP executable's path. Symfony simplifies the process of finding this executable's location, which can vary across various environments. This tutorial explains how to find PHP executable in Symfony 7.

Symfony provides the PhpExecutableFinder class, which returns the absolute path of the PHP executable present on the server. This class employs various ways to locate the PHP executable, ensuring compatibility across different environments.

<?php

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

use Symfony\Component\Process\PhpExecutableFinder;

$finder = new PhpExecutableFinder();
$phpBinaryPath = $finder->find();

echo $phpBinaryPath; // /usr/bin/php
