	      "33" => "澳门", 
	      "34" => "台湾" 
	    ); 
	 
	    function find(&$item,$key,$data){ 
	        global $k; 
	        if(preg_match("/$item/u",$data)){ 
	           $k = $key; 
	        } 
	    } 
	 
	    function get_data_arr($key){ 
	        if(!file_exists("./data/city{$key}.xml")){ 
	            $c =file_get_contents( "http://m.weather.com.cn/data5/city{$key}.xml" );   
	            file_put_contents("./data/city{$key}.xml",$c); 
	        } 
	        else{ 
	            $c = file_get_contents("./data/city{$key}.xml"); 
	        } 
	       $arr = explode(",",$c); 
	       foreach($arr as $v){ 
	           $data = explode("|",$v); 
	           $ret[$data[0]] = $data[1]; 
	       } 
	       return $ret; 
	    } 
	 
	    array_walk($p_arr,'find',$p); 
	    array_walk(get_data_arr($k),'find',$p); 
	    array_walk(get_data_arr($k),'find',$p); 
	    $ccode = get_data_arr($k); 
	    echo file_get_contents("http://m.weather.com.cn/data/{$ccode[$k]}.html");
