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"
)

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,))

据我所知,没有内置的方法可以做到这一点,但它就像一个简单的循环一样简单:
$obj= new stdClass();
foreach ($array as $k=> $v) {
$obj->{$k} = $v;
}
如果你需要递归地构建你的对象,你可以详细说明。
我使用的一个(它是类成员):
const MAX_LEVEL = 5; // change it as needed
public function arrayToObject($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;
}
如果你需要将一个数组强制转换为一个特定的类(在我的例子中,我需要对象类型为Google_Service_AndroidPublisher_Resource_Inappproducts),你可以像这样从stdClass中将类名str_replace为预期的类:
function castArrayToClass(array $array, string $className)
{
//first cast the array to stdClass
$subject = serialize((object)$array);
//then change the class name
$converted = str_replace(
'O:8:"stdClass"',
'O:'.strlen($className).':"'.$className.'"',
$subject
);
unset($subject);
return unserialize($converted);
}
我也有这个问题,但我注意到json_decode将JSON数组转换为对象。
所以,我通过使用json_encode($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);
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; }
