php对象和数组的相互转换，Array2object()、Object2array()

    function array2object($array) {
  
        if (is_array($array)) {
            $obj = new StdClass();
      
            foreach ($array as $key => $val){
                $obj->$key = $val;
            }
        }
        else { $obj = $array; }
      
        return $obj;
    }
      
    function object2array($object) {
        if (is_object($object)) {
            foreach ($object as $key => $value) {
                $array[$key] = $value;
            }
        }
        else {
            $array = $object;
        }
        return $array;
    }

　　$array = array('foo' => 'bar', 'one' => 'two', 'three' => 'four');

　　$obj = array2object($array);     
　　print $obj->one; // output's "two"

　　$arr = object2array($obj);
　　print $arr['foo']; // output's bar
