PHP代码

<?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.'/';
        else    self::$_path = APP_PATH.'/templates/';
        self::$_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();
