php多层数组与对象的转换实例代码

多层数组和对象转化的用途很简单,便于处理WebService中多层数组和对象的转化

简单的(array)和(object)只能处理单层的数据,对于多层的数组和对象转换则无能为力。

通过json_decode(json_encode($object)可以将对象一次性转换为数组,但是object中遇到非utf-8编码的非ascii字符则会出现问题,比如gbk的中文,何况json_encode和decode的性能也值得疑虑。

下面上代码:

复制代码 代码如下:

<?php
 function objectToArray($d) {
  if (is_object($d)) {
   // Gets the properties of the given object
   // with get_object_vars function
   $d = get_object_vars($d);
  }

  if (is_array($d)) {
   /*
   * Return array converted to object
   * Using __FUNCTION__ (Magic constant)
   * for recursive call
   */
   return array_map(__FUNCTION__, $d);
  }
  else {
   // Return array
   return $d;
  }
 }

 function arrayToObject($d) {
  if (is_array($d)) {
   /*
   * Return array converted to object
   * Using __FUNCTION__ (Magic constant)
   * for recursive call
   */
   return (object) array_map(__FUNCTION__, $d);
  }
  else {
   // Return object
   return $d;
  }
 }
 // Useage:
 // Create new stdClass Object  
        $init = new stdClass;
 // Add some test data
 $init->foo = "Test data";
 $init->bar = new stdClass;
 $init->bar->baaz = "Testing";
 $init->bar->fooz = new stdClass;
 $init->bar->fooz->baz = "Testing again";
 $init->foox = "Just test";

 // Convert array to object and then object back to array
 $array = objectToArray($init);
 $object = arrayToObject($array);

 // Print objects and array
 print_r($init);
 echo "\n";
 print_r($array);
 echo "\n";
 print_r($object);
?>
