php简单对象与数组的转换函数代码(php多层数组和对象的转换)

function arraytoobject($e){
if( gettype($e)!='array' ) return;
foreach($e as $k=>$v){
if( gettype($v)=='array' || gettype($v)=='object' )
$e[$k]=(object)arraytoobject($v);
}
return (object)$e;
}

function objecttoarray($e){
$e=(array)$e;
foreach($e as $k=>$v){
if( gettype($v)=='resource' ) return;
if( gettype($v)=='object' || gettype($v)=='array' )
$e[$k]=(array)objecttoarray($v);
}
return $e;
}

php多层数组和对象的转换
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：

<?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);
?>
