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($object)可以将对象一次性转换为数组，但是object中遇到非utf-8编码的非ascii字符则会出现问题，比如gbk的中文，何况json_encode和decode的性能也值得疑虑。
下面上代码：
代码如下:
PHP
function objectToArray($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($object);
?>
function objectToArray($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);
?>
