PHPCMS源码构造分析

/**
* 构造函数
*/
public function __construct() {
$param = pc_base::load_sys_class('param');//加载param类并初始化
define('ROUTE_M', $param->route_m());
define('ROUTE_C', $param->route_c());
define('ROUTE_A', $param->route_a());
$this->init();
}

//路由配置
private $route_config = '';
public function __construct() {
if(!get_magic_quotes_gpc()) {
$_POST = new_addslashes($_POST);
$_GET = new_addslashes($_GET);
$_REQUEST = new_addslashes($_REQUEST);
$_COOKIE = new_addslashes($_COOKIE);
}
$this->route_config = pc_base::load_config('route', SITE_URL) ? pc_base::load_config('route', SITE_URL) : pc_base::load_config('route', 'default');
if(isset($this->route_config['data']['POST']) && is_array($this->route_config['data']['POST'])) {
foreach($this->route_config['data']['POST'] as $_key => $_value) {
if(!isset($_POST[$_key])) $_POST[$_key] = $_value;
}
}
if(isset($this->route_config['data']['GET']) && is_array($this->route_config['data']['GET'])) {
foreach($this->route_config['data']['GET'] as $_key => $_value) {
if(!isset($_GET[$_key])) $_GET[$_key] = $_value;
}
}
if(isset($_GET['page'])) $_GET['page'] = max(intval($_GET['page']),1);
return true;
}

array(
'default'=>array('m'=>'content', 'c'=>'index', 'a'=>'init'),
);

define('ROUTE_M', $param->route_m());
define('ROUTE_C', $param->route_c());
define('ROUTE_A', $param->route_a());
$param->route_m()等三个方法到底干了些呢，代码如下
/**
* 获取模型
*/
public function route_m() {
$m = isset($_GET['m']) && !empty($_GET['m']) ? $_GET['m'] : (isset($_POST['m']) && !empty($_POST['m']) ? $_POST['m'] : '');
if (empty($m)) {
return $this->route_config['m'];
} else {
return $m;
}
}
