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); 
?>
