command.php: PHP_BINDIR fails on Magento Cloud - should be configurable via .env

[constantinospan]

Preconditions

1. Magento 2.4.7 on Adobe Commerce Cloud
2. MFTF 4.7.5
3. Running tests from local against cloud environment
4. Tests use <magentoCLI> actions

Steps to reproduce

1. Deploy to Adobe Commerce Cloud
2. Run vendor/bin/mftf build:project
3. Run vendor/bin/mftf doctor or any test with <magentoCLI> action

Expected result

Magento CLI commands execute successfully via command.php endpoint.

Actual result

HTTP 403: "Given command not found valid in Magento CLI Command list."

Root cause: Line 22 in command.php:

$php = PHP_BINDIR ? PHP_BINDIR . '/php' : 'php';

On Magento Cloud, PHP_BINDIR points to /usr/bin/php which is an incompatible PHP version. The correct PHP 8.3 is available via php in PATH, but the code never falls back to it because PHP_BINDIR is always set.

This is similar to issue #216 (PHP-FPM), which was fixed in PR #217 by switching from PHP_BINARY to PHP_BINDIR. That fixed PHP-FPM but broke Magento Cloud.

Simple fix: Make the PHP binary configurable in .env:

 $php = $_ENV['MFTF_PHP_BINARY'] ?? (PHP_BINDIR ? PHP_BINDIR . '/php' : 'php');

Then users can set MFTF_PHP_BINARY=php in .env for cloud environments.

Currently, we have to manually edit the file after every build:project, which isn't sustainable.
