如何将这样的数组转换为对象?
[128] => Array
(
[status] => "Figure A.
Facebook's horizontal scrollbars showing up on a 1024x768 screen resolution."
)
[129] => Array
(
[status] => "The other day at work, I had some spare time"
)

我使用的一个(它是类成员):
const MAX_LEVEL = 5; // change it as needed
public function arrayToObject($a, $level=0)
{
if(!is_array($a)) {
throw new InvalidArgumentException(sprintf('Type %s cannot be cast, array expected', gettype($a)));
}
if($level > self::MAX_LEVEL) {
throw new OverflowException(sprintf('%s stack overflow: %d exceeds max recursion level', __METHOD__, $level));
}
$o = new stdClass();
foreach($a as $key => $value) {
if(is_array($value)) { // convert value recursively
$value = $this->arrayToObject($value, $level+1);
}
$o->{$key} = $value;
}
return $o;
}
其他回答
受到所有这些代码的启发,我尝试创建一个增强版本,支持:特定的类名,避免构造函数方法,'beans'模式和严格模式(仅设置现有属性):
class Util {
static function arrayToObject($array, $class = 'stdClass', $strict = false) {
if (!is_array($array)) {
return $array;
}
//create an instance of an class without calling class's constructor
$object = unserialize(
sprintf(
'O:%d:"%s":0:{}', strlen($class), $class
)
);
if (is_array($array) && count($array) > 0) {
foreach ($array as $name => $value) {
$name = strtolower(trim($name));
if (!empty($name)) {
if(method_exists($object, 'set'.$name)){
$object->{'set'.$name}(Util::arrayToObject($value));
}else{
if(($strict)){
if(property_exists($class, $name)){
$object->$name = Util::arrayToObject($value);
}
}else{
$object->$name = Util::arrayToObject($value);
}
}
}
}
return $object;
} else {
return FALSE;
}
}
}
你也可以通过在变量的左边添加(object)来创建一个新对象。
<?php
$a = Array
( 'status' => " text" );
var_dump($a);
$b = (object)$a;
var_dump($b);
var_dump($b->status);

使用我创建的这个函数:
function buildObject($class,$data){
$object = new $class;
foreach($data as $key=>$value){
if(property_exists($class,$key)){
$object->{'set'.ucfirst($key)}($value);
}
}
return $object;
}
用法:
$myObject = buildObject('MyClassName',$myArray);
简单的方法是
$object = (object)$array;
但这不是你想要的。如果你想要对象,你想要实现一些东西,但这在这个问题中是缺失的。仅仅为了使用对象而使用对象是没有意义的。
function object_to_array($data)
{
if (is_array($data) || is_object($data))
{
$result = array();
foreach ($data as $key => $value)
{
$result[$key] = object_to_array($value);
}
return $result;
}
return $data;
}
function array_to_object($data)
{
if (is_array($data) || is_object($data))
{
$result= new stdClass();
foreach ($data as $key => $value)
{
$result->$key = array_to_object($value);
}
return $result;
}
return $data;
}
