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

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) {

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;

// convert array to object and then object back to array

$object = arraytoobject($array);

// print objects and array
print_r($init);
