一个网友写的地市联动的php分类程序,大家可参考参考。

写一个函数,将数据

 代码如下 复制代码
$array = array(
    0=>array("","河北"),
    1=>array("","北京"),
    2=>array(0,"保定"),
    3=>array(1,"海淀"),
    4=>array(3,"中关村"),
    5=>array(2,"涿州")
);


处理后返回如下:
河北
-保定
--涿州
北京
-海淀
--中关村

 

 代码如下 复制代码
function typeArray($array){
   $con = null;
   foreach ($array as $k=>$v){
        $na[$k] = is_numeric($v[0]) ? $na[$v[0]].$k."|" : $k."|";
    }
   asort($na);
   foreach ($na as $k=>$v){
     $s = substr_count($v,"|");
      $con .= str_repeat("-",($s-1)).$array[$k][1]."n";
    }
    return $con;
}
