PHP 自动加载对象(以MVC框架为例)
<?php
class autoloader
{
public static
$loader;
public static function
init()
{
if
(self::$loader ==
NULL)
self::$loader = new
self();
return
self::$loader;
}
public function __construct()
{
spl_autoload_register(array($this,'model'));
spl_autoload_register(array($this,'helper'));
spl_autoload_register(array($this,'controller'));
spl_autoload_register(array($this,'library'));
}
public function
library($class)
{
set_include_path(get_include_path().PATH_SEPARATOR.'/lib/');
spl_autoload_extensions('.library.php');
spl_autoload($class);
}
public function
controller($class)
{
$class =
preg_replace('/_controller$/ui','',$class);
set_include_path(get_include_path().PATH_SEPARATOR.'/controller/');
spl_autoload_extensions('.controller.php');
spl_autoload($class);
}
public function
model($class)
{
$class =
preg_replace('/_model$/ui','',$class);
set_include_path(get_include_path().PATH_SEPARATOR.'/model/');
spl_autoload_extensions('.model.php');
spl_autoload($class);
}
public function
helper($class)
{
$class =
preg_replace('/_helper$/ui','',$class);
set_include_path(get_include_path().PATH_SEPARATOR.'/helper/');
spl_autoload_extensions('.helper.php');
spl_autoload($class);
}
}
//call
autoloader::init();
?>
