<?php
require_once('/path/to/requirements/RequirementsChecker.php');

$config = [

'by' => 'Yii Framework',
'memo' => 'PHP 7.4.0 or higher is required.',
],
[
'name' => 'PDO MySQL extension',
'mandatory' => false,
'condition' => extension_loaded('pdo_mysql'),

);

$requirementsChecker = new RequirementsChecker();
