 * YiiRequirementChecker allows checking, if current system meets the requirements for running the Yii application.
 * This class allows rendering of the check report for the web and console application interface.
 *
 * Example:
 *
 * ```php
 * require_once 'path/to/YiiRequirementChecker.php';
 * $requirementsChecker = new YiiRequirementChecker();
 * $requirements = [
 *     [
 *         'name' => 'PHP Some Extension',
 *         'mandatory' => true`,
 *         'condition' => extension_loaded('some_extension'),
 *         'by' => 'Some application feature',
 *         'memo' => 'PHP extension "some_extension" required',
 *     ],
 * ];
 * $requirementsChecker
 *     ->check($requirements)
 *     ->render();
 * ```
 *
 * If you wish to render the report with your own representation, use {@see getResult()} instead of {@see render()}.
 *
 * Requirement condition could be in format "eval:PHP expression".
 * In this case specified PHP expression will be evaluated in the context of this class instance.
 * For example:
 *
 * ```php
 * $requirements = [
 *     [
 *         'name' => 'Upload max file size',
 *         'condition' => 'eval:$this->checkUploadMaxFileSize("5M")',
