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"
)

你也可以使用ArrayObject,例如:
<?php
$arr = array("test",
array("one"=>1,"two"=>2,"three"=>3),
array("one"=>1,"two"=>2,"three"=>3)
);
$o = new ArrayObject($arr);
echo $o->offsetGet(2)["two"],"\n";
foreach ($o as $key=>$val){
if (is_array($val)) {
foreach($val as $k => $v) {
echo $k . ' => ' . $v,"\n";
}
}
else
{
echo $val,"\n";
}
}
?>
//Output:
2
test
one => 1
two => 2
three => 3
one => 1
two => 2
three => 3
其他回答
这里有三种方法:
Fake a real object: class convert { public $varible; public function __construct($array) { $this = $array; } public static function toObject($array) { $array = new convert($array); return $array; } } Convert the array into an object by casting it to an object: $array = array( // ... ); $object = (object) $array; Manually convert the array into an object: $object = object; foreach ($arr as $key => $value) { $object->{$key} = $value; }
CakePHP有一个递归的Set::map类,基本上是将数组映射到对象。为了使对象看起来像你想要的样子,你可能需要改变数组的样子。
http://api.cakephp.org/view_source/set/#line-158
最坏的情况下,您可能会从这个函数中得到一些想法。
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);

可以使用(object)函数将数组转换为对象。
$arr= [128=> ['status'=>
'Figure A. Facebook \'s horizontal scrollbars showing up on a 1024x768 screen resolution.'],
129=>['status'=>'The other day at work, I had some spare time']];
$ArrToObject=(object)$arr;
var_dump($ArrToObject);
结果将是一个包含数组的对象:
对象(stdClass)#1048(2){[128]=>数组(1){ ["地位"]= > 字符串(87)“图a: Facebook的水平滚动条显示在1024x768分辨率的屏幕上。”} [129]=>数组(1){ ["地位"]= > 字符串(44)“前几天上班,我有一些空闲时间”}}
受到所有这些代码的启发,我尝试创建一个增强版本,支持:特定的类名,避免构造函数方法,'beans'模式和严格模式(仅设置现有属性):
class Util {
static function arrayToObject($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;
}
}
}
