*  process-oriented model

```php

$user = 'root';
$pass = '';
$data_base = 'test';

mysql_connect($host, $user, $pass);
mysql_select_db($data_base);

if ($_SERVER['REQUEST_METHOD'] !== 'POST') {
  	$data = array(
		'status' => 100,
		'desc' => 'wrong method'
	);
	echo json_encode($data);
  	exit();
}

	$data = array(
		'status' => 100,

	echo json_encode($data);
	exit();

* object-oriented model
