What steps can be taken to ensure that the PHP environment on the test server matches that of the production server?

To ensure that the PHP environment on the test server matches that of the production server, you can create a PHP script that checks for the necessary PHP extensions, versions, and configurations. This script can be run on both servers to identify any discrepancies and ensure that the necessary adjustments are made to match the production environment. 

<?php
// Check for required PHP extensions
$required_extensions = ['pdo_mysql', 'openssl', 'curl'];
$missing_extensions = array_diff($required_extensions, get_loaded_extensions());
if (!empty($missing_extensions)) {
    echo 'Missing required PHP extensions: ' . implode(', ', $missing_extensions);
}

// Check for required PHP version
$required_php_version = '7.4.0';
if (version_compare(PHP_VERSION, $required_php_version, '<')) {
    echo 'PHP version must be at least ' . $required_php_version;
}

// Check for required PHP configurations
$required_configs = ['memory_limit' => '128M', 'max_execution_time' => 30];
foreach ($required_configs as $config => $value) {
    if (ini_get($config) < $value) {
        echo 'PHP configuration ' . $config . ' must be at least ' . $value;
    }
}
?>
