【php中对象转换数组对象】php中对象转换数组与数组转换对象实例

用stdClass转换数组为对象                                                                                  

Php代码

 代码如下

$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

$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

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

$array = array(1 => php, 
           2 => java, 
           3 => c ); 

$arrayobject = new ArrayObject($array); 

var_dump($arrayobject); 
?>

运行结果：

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