CodeIgniter.php

PHP Code:

   /**
    * Constructor.
    */
    public function __construct(App $config)
    {
        if (version_compare(PHP_VERSION, self::MIN_PHP_VERSION, '<')) {
            // @codeCoverageIgnoreStart
            $message = extension_loaded('intl')
                ? lang('Core.invalidPhpVersion', [self::MIN_PHP_VERSION, PHP_VERSION])
                : sprintf('Your PHP version must be %s or higher to run CodeIgniter. Current version: %s', self::MIN_PHP_VERSION, PHP_VERSION);

            exit($message);
            // @codeCoverageIgnoreEnd
        }

        $this->startTime = microtime(true);
        $this->config    = $config;
    }
