<div><?php
define('APP_PATH', __DIR__);
class Template{
private static $_vars;
private static $_path;
private static $_prefix;
private function __construct() {}
public static function init($path = null) {
if(isset($path)&&($path!=''))self::$_path=APP_PATH.'/templates/'.$path.'/';
elseself::$_path = APP_PATH.'/templates/';
self::$_vars = array();
}
public static function set_path($path) {
self::$_path = $path;
}
public static function set_prefix($prefix) {
self::$_prefix = $prefix;
}
public static function assign($key, $value = null)
 {if(!isset(self::$_vars))self::init();
if (is_array($key))self::$_vars = array_merge(self::$_vars,$key);
 elseif (($key != '')&&(isset($value)))
 self::$_vars[$key] = $value;
 }
public static function fetch($file) {

if(!isset(self::$_vars))self::init();
if(count(self::$_vars)>0)
{extract(self::$_vars,EXTR_PREFIX_ALL,self::$_prefix);
self::$_vars = array();
}
ob_start();
include self::$_path . $file ;
$contents = ob_get_contents();
ob_end_clean();
self::$_path = null;
return preg_replace('!\s+!', ' ', $contents);
}
}
?></div>
