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"
)

快速攻击:
// assuming $var is a multidimensional array
$obj = json_decode (json_encode ($var), FALSE);
不漂亮,但很好用。

实际上,如果你想在多维数组中使用这个你就需要使用一些递归。
static public function array_to_object(array $array)
{
foreach($array as $key => $value)
{
if(is_array($value))
{
$array[$key] = self::array_to_object($value);
}
}
return (object)$array;
}
你可以使用反射:
<?php
$array = ['name'=>'maria','age'=>33];
class Person {
public $name;
public $age;
public function __construct(string $name, string $age){
$this->name = $name;
$this->age = $age;
}
}
function arrayToObject(array $array, string $class_name){
$r = new ReflectionClass($class_name);
$object = $r->newInstanceWithoutConstructor();
$list = $r->getProperties();
foreach($list as $prop){
$prop->setAccessible(true);
if(isset($array[$prop->name]))
$prop->setValue($object, $array[$prop->name]);
}
return $object;
}
$pessoa1 = arrayToObject($array, 'Person');
var_dump($pessoa1);
有点复杂,但很容易扩展的技术:
假设你有一个数组
$a = [
'name' => 'ankit',
'age' => '33',
'dob' => '1984-04-12'
];
假设您有一个Person类,它可能有来自这个数组的或多或少的属性。例如
class Person
{
private $name;
private $dob;
private $age;
private $company;
private $city;
}
如果你还想把数组改成person对象。你可以使用ArrayIterator类。
$arrayIterator = new \ArrayIterator($a); // Pass your array in the argument.
现在你有了迭代器对象。
创建一个扩展FilterIterator class的类;你必须定义抽象方法accept。遵循示例
class PersonIterator extends \FilterIterator
{
public function accept()
{
return property_exists('Person', parent::current());
}
}
上面的实现只在类中存在该属性时才会绑定它。
在类PersonIterator中再添加一个方法
public function getObject(Person $object)
{
foreach ($this as $key => $value)
{
$object->{'set' . underscoreToCamelCase($key)}($value);
}
return $object;
}
确保在类中定义了mutator。 现在,您可以在想要创建对象的地方调用这些函数。
$arrayiterator = new \ArrayIterator($a);
$personIterator = new \PersonIterator($arrayiterator);
$personIterator->getObject(); // this will return your Person Object.
我也有这个问题,但我注意到json_decode将JSON数组转换为对象。
所以,我通过使用json_encode($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);
多维数组转换为对象。此代码用于转换必应搜索API的尝试和捕获方法。
try {
// Perform the Web request and get the JSON response
$context = stream_context_create($options);
$results = file_get_contents($url . "?cc=" . $country . "&category=" . $type, false, $context);
$results = json_decode($results);
return response()->json($results);
} catch (\Exception $e) {
$results = array('value' => array(
(object) array(
"name" => "Unable to Retrive News",
"url" => "http://www.sample.com/",
"image" => (object) array("thumbnail" => (object) array("contentUrl" => "")),
"publishedAt" => "",
"description" => "")
)
);
$results = (object) $results;
return response()->json($results);
}
