php中对象转换数组与数组转换对象实例

本文章来介绍了在php中如何把数组转换成对象或是把对象转换成数组对象，有需要的同学和朋友们可以参考一下本文章的这个实例啊。

<script>ec(2);</script>

用stdClass转换数组为对象                                                                                  

Php代码

代码如下

复制代码

$arr = array();                                            $arr['a'] = 1;                                               $arr['b'] = 2;                                               $arr['c'] = 3;                                               $arr = array();                                           $arr['a'] = 1;                                              $arr['b'] = 2;                                              $arr['c'] = 3;

用stdClass转换后：

Php代码

代码如下

复制代码

$object   = new StdClass;                          $object->a = 1;                                          $object->b = 2;                                          $object->c = 3;                                          $object   = new StdClass;                           $object->a = 1;                                           $object->b = 2;                                           $object->c = 3;

stdClass是PHP的一个基类，所有的类几乎都继承这个类，所以任何时候都可以被new，可以让这个变量成为一个object。同时，这个基类又有一个特殊的地方，就是没有方法

我应用的地方是simplexml中的simplexml_load_string()上，因为返回的全是对象，如果提取数据比较麻烦，所以应用了下面的函数

代码如下	复制代码
function object_to_array($obj) { $_arr = is_object($obj) ? get_object_vars($obj) : $obj; foreach ($_arr as $key => $val) { $val = (is_array($val) || is_object($val)) ? object_to_array($val) : $val; $arr[$key] = $val; } return $arr; }

数组转换成对象

代码如下	复制代码
$array = array(1 => php,             2 => java,             3 => c );  $arrayobject = new ArrayObject($array);  var_dump($arrayobject);  ?>

运行结果：

代码如下	复制代码
object(ArrayObject)#1 (1) { ["storage":"ArrayObject":private]=> array(3) { [1]=> string(3) "php" [2]=> string(4) "java" [3]=> string(3) "c " }}

一个类：ArrayObject，可以直接将数组转化为对象                                             

Php代码

代码如下

复制代码

$array = array('1' => 'one',                                      '2' => 'two',                                                 '3' => 'three');                              $arrayobject = new ArrayObject($array);   var_dump($arrayobject);                            $array = array('1' => 'one',                                        '2' => 'two',                                                 '3' => 'three');                              $arrayobject = new ArrayObject($array);   var_dump($arrayobject);

                     
结果：

代码如下

复制代码

Php代码 object(ArrayObject)#1 (3) {                        [1]=>                                                        string(3) "one"                                         [2]=>                                                        string(3) "two"                                          [3]=>                                                        string(5) "three"                                       }
