spl_autoload_register()函数中没有参数,则会自动默认实现void spl_autoload ( string $class_name [,string $file_extensions ] )函数,默认支持.php和.ini
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();
?>
也可以根据自己的需要来设计实现
