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"
)

一个衬套
$object= json_decode(json_encode($result_array, JSON_FORCE_OBJECT));
其他回答
容易:
$object = json_decode(json_encode($array));
例子:
$array = array(
'key' => array(
'k' => 'value',
),
'group' => array('a', 'b', 'c')
);
$object = json_decode(json_encode($array));
那么，以下是正确的:
$object->key->k === 'value';
$object->group === array('a', 'b', 'c')
Code
此函数的工作原理与json_decode(json_encode($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,))
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);
}
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);
}
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。
