Utilities

The crystal microframework offers some utilities, like the 404 route.
But there are other utilities offered!

The utilities are:

• an Autoloader based on the PSR-0 standard
• a Dependency Injection system, with a signature based on PSR-11
• a Template Engine available from PHP 5
• a Logger available from PHP 5, with a signature based on PSR-3
• storable Settings
• a Database interaction system
• a Double access utility

Excluding the utilities described above, other utilities are:

$server = $mf('server');

var_dump($server['SERVER_NAME']); // localhost

$mf('get') // -> $_GET (with double access)
$mf('post') // -> $_POST (with double access)
$mf('cookie') // -> $_COOKIE (with double access)
$mf('env') // -> $_ENV (with double access)
$mf('request') // -> $_REQUEST (with double access)
$mf('server') // -> $_SERVER (with double access)
