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"
)

当前回答
我肯定会用这样一种干净的方式:
<?php
class Person {
private $name;
private $age;
private $sexe;
function __construct ($payload)
{
if (is_array($payload))
$this->from_array($payload);
}
public function from_array($array)
{
foreach(get_object_vars($this) as $attrName => $attrValue)
$this->{$attrName} = $array[$attrName];
}
public function say_hi ()
{
print "hi my name is {$this->name}";
}
}
print_r($_POST);
$mike = new Person($_POST);
$mike->say_hi();
?>

你会得到这个:
我发现这更符合逻辑的比较以上的答案从对象应该用于他们的目的(封装可爱的小对象)。
此外,使用get_object_vars确保在被操纵的对象中没有创建额外的属性(您不希望汽车有姓,也不希望人有4个轮子)。
其他回答
通过使用(array)和(object)作为前缀,可以简单地将对象数组转换为标准数组,反之亦然
<?php
//defining an array
$a = array('a'=>'1','b'=>'2','c'=>'3','d'=>'4');
//defining an object array
$obj = new stdClass();
$obj->a = '1';
$obj->b = '2';
$obj->c = '3';
$obj->d = '4';
print_r($a);echo '<br>';
print_r($obj);echo '<br>';
//converting object array to array
$b = (array) $obj;
print_r($b);echo '<br>';
//converting array to object
$c = (object) $a;
print_r($c);echo '<br>';
?>
您可以简单地使用类型强制转换将数组转换为对象。
// *convert array to object* Array([id]=> 321313[username]=>shahbaz)
$object = (object) $array_name;
//now it is converted to object and you can access it.
echo $object->username;
这个方法对我很管用
function array_to_obj($array, &$obj)
{
foreach ($array as $key => $value)
{
if (is_array($value))
{
$obj->$key = new stdClass();
array_to_obj($value, $obj->$key);
}
else
{
$obj->$key = $value;
}
}
return $obj;
}
function arrayToObject($array)
{
$object= new stdClass();
return array_to_obj($array,$object);
}
用法:
$myobject = arrayToObject($array);
print_r($myobject);
返回:
[127] => stdClass Object
(
[status] => Have you ever created a really great looking website design
)
[128] => stdClass Object
(
[status] => Figure A.
Facebook's horizontal scrollbars showing up on a 1024x768 screen resolution.
)
[129] => stdClass Object
(
[status] => The other day at work, I had some spare time
)
像往常一样,你可以这样循环:
foreach($myobject as $obj)
{
echo $obj->status;
}
我也有这个问题,但我注意到json_decode将JSON数组转换为对象。
所以,我通过使用json_encode($PHPArray)来实现我的解决方案,它返回对象的JSON字符串,然后我用Json_decode($string)解码字符串,它将返回一个完美的结构化对象。 速记
$object = json_decode(json_encode($array));
Or
$jsonString = json_encode($array);
$object = json_decode($jsonString);
Code
此函数的工作原理与json_decode(json_encode($arr), false)相同。
function arrayToObject(array $arr)
{
$flat = array_keys($arr) === range(0, count($arr) - 1);
$out = $flat ? [] : new \stdClass();
foreach ($arr as $key => $value) {
$temp = is_array($value) ? $this->arrayToObject($value) : $value;
if ($flat) {
$out[] = $temp;
} else {
$out->{$key} = $temp;
}
}
return $out;
}
测试
测试1:平面阵列
$arr = ["a", "b", "c"];
var_export(json_decode(json_encode($arr)));
var_export($this->arrayToObject($arr));
输出:
array(
0 => 'a',
1 => 'b',
2 => 'c',
)
array(
0 => 'a',
1 => 'b',
2 => 'c',
)
测试2:对象数组
$arr = [["a" => 1], ["a" => 1], ["a" => 1]];
var_export(json_decode(json_encode($arr)));
var_export($this->arrayToObject($arr));
输出:
array(
0 => stdClass::__set_state(array('a' => 1,)),
1 => stdClass::__set_state(array('a' => 1,)),
2 => stdClass::__set_state(array('a' => 1,)),
)
array(
0 => stdClass::__set_state(array('a' => 1,)),
1 => stdClass::__set_state(array('a' => 1,)),
2 => stdClass::__set_state(array('a' => 1,)),
)
测试3:对象
$arr = ["a" => 1];
var_export(json_decode($arr));
var_export($this->arrayToObject($arr));
输出:
stdClass::__set_state(array('a' => 1,))
stdClass::__set_state(array('a' => 1,))
