Convert laravel object to array
提问by Your Friend
Laravel output:
Laravel 输出：
Array
(
[0] = stdClass Object
(
[ID] = 5
)
[1] = stdClass Object
(
[ID] = 4
)
)
I want to convert this into normal array. Just want to remove that stdClass Object. I also tried using ->toArray();but I get an error:
我想将其转换为普通数组。只是想删除那个stdClass Object。我也尝试使用，->toArray();但出现错误：
Call to a member function toArray() on a non-object.
在非对象上调用成员函数 toArray()。
How can I fix this?
我怎样才能解决这个问题？

UPDATE since version 5.4 of Laravel it is no longer possible.
更新自 Laravel 5.4 版以来不再可能。
You can change your db config, like @Varun suggested, or if you want to do it just in this very case, then:
您可以像@Varun 建议的那样更改您的数据库配置，或者如果您只想在这种情况下这样做，则：
DB::setFetchMode(PDO::FETCH_ASSOC);
// then
DB::table(..)->get(); // array of arrays instead of objects
// of course to revert the fetch mode you need to set it again
DB::setFetchMode(PDO::FETCH_CLASS);
For New Laravel above 5.4 (Ver > 5.4) see https://laravel.com/docs/5.4/upgradefetch mode section
对于高于 5.4 (Ver > 5.4) 的新 Laravel，请参阅https://laravel.com/docs/5.4/upgradefetch mode 部分
Event::listen(StatementPrepared::class, function ($event) {
$event->statement->setFetchMode(...);
});
回答by Maurice
foreach($yourArrayName as $object)
{
$arrays[] = $object->toArray();
}
// Dump array with object-arrays
dd($arrays);
Or when toArray()fails because it's a stdClass
或者当toArray()因为它是一个 stdClass 而失败时
foreach($yourArrayName as $object)
{
$arrays[] = (array) $object;
}
// Dump array with object-arrays
dd($arrays);
Not working? Maybe you can find your answer here:

this worked for me:
这对我有用：
$data=DB::table('table_name')->select(.......)->get();
$data=array_map(function($item){
return (array) $item;
},$data);
or
或者
$data=array_map(function($item){
return (array) $item;
},DB::table('table_name')->select(.......)->get());

You can also get all the result always as array by changing
您还可以通过更改始终以数组形式获取所有结果
// application/config/database.php
'fetch' => PDO::FETCH_CLASS,
// to
'fetch' => PDO::FETCH_ASSOC,
Hope this will help.
希望这会有所帮助。

Just in case somebody still lands here looking for an answer. It can be done using plain PHP. An easier way is to reverse-json the object.
以防万一有人仍然在这里寻找答案。它可以使用普通的 PHP 来完成。一种更简单的方法是反向 json 对象。
function objectToArray(&$object)
{
return @json_decode(json_encode($object), true);
}

this worked for me in laravel 5.4
这在 Laravel 5.4 中对我有用
$partnerProfileIds = DB::table('partner_profile_extras')->get()->pluck('partner_profile_id');
$partnerProfileIdsArray = $partnerProfileIds->all();
output
输出
array:4 [▼
0 => "8219c678-2d3e-11e8-a4a3-648099380678"
1 => "28459dcb-2d3f-11e8-a4a3-648099380678"
2 => "d5190f8e-2c31-11e8-8802-648099380678"
3 => "6d2845b6-2d3e-11e8-a4a3-648099380678"

You need to iterate over the array
您需要遍历数组
for ($i = 0, $c = count($array); $i < $c; ++$i) {
$array[$i] = (array) $array[$i];
}
ans use (array)conversion because you have array of objects of Std class and not object itself
ans 使用(array)转换，因为您有 Std 类的对象数组而不是对象本身
Example:
例子：
$users = DB::table('users')->get();
var_dump($users);
echo "<br /><br />";
for ($i = 0, $c = count($users); $i < $c; ++$i) {
$users[$i] = (array) $users[$i];
}
var_dump($users);
exit;
Output for this is:
输出为：
array(1) { [0]=> object(stdClass)#258 (8) { ["id"]=> int(1) ["user_name"]=> string(5) "admin" ["email"]=> string(11) "admin@admin" ["passwd"]=> string(60) "y$T/0fW18gPGgz0CILTy2hguxNpcNjYZHsTyf5dvpor9lYMw/mtKYfi" ["balance"]=> string(4) "0.00" ["remember_token"]=> string(60) "moouXQOJFhtxkdl9ClEXYh9ioBSsRp28WZZbLPkJskcCr0325TyrxDK4al5H" ["created_at"]=> string(19) "2014-10-01 12:00:00" ["updated_at"]=> string(19) "2014-09-27 12:20:54" } }
array(1) { [0]=> array(8) { ["id"]=> int(1) ["user_name"]=> string(5) "admin" ["email"]=> string(11) "admin@admin" ["passwd"]=> string(60) "y$T/0fW18gPGgz0CILTy2hguxNpcNjYZHsTyf5dvpor9lYMw/mtKYfi" ["balance"]=> string(4) "0.00" ["remember_token"]=> string(60) "moouXQOJFhtxkdl9ClEXYh9ioBSsRp28WZZbLPkJskcCr0325TyrxDK4al5H" ["created_at"]=> string(19) "2014-10-01 12:00:00" ["updated_at"]=> string(19) "2014-09-27 12:20:54" } }
as expected. Object of stdClasshas been converted to array.
正如预期的那样。的对象stdClass已转换为数组。

If you want to get only ID in array, can use array_map:
如果只想获取数组中的 ID，可以使用 array_map：
$data = array_map(function($object){
return $object->ID;
}, $data);
With that, return an array with ID in every pos.
这样，在每个位置返回一个带有 ID 的数组。

Its very simple. You can use like this :-
它非常简单。你可以这样使用：-
Suppose You have one users table and you want to fetch the id only
$users = DB::table('users')->select('id')->get();
$users = json_decode(json_encode($users)); //it will return you stdclass object
$users = json_decode(json_encode($users),true); //it will return you data in array
echo '<pre>'; print_r($users);
Hope it helps
希望能帮助到你

It's also possible to typecast an object to an array. That worked for me here.
也可以将对象类型转换为数组。这对我有用。
(array) $object;
(array) $object;
will convert
会转换
stdClass Object
(
[id] => 4
)
to
到
Array(
[id] => 4
)
Had the same problem when trying to pass data from query builder to a view. Since data comes as object. So you can do:
尝试将数据从查询构建器传递到视图时遇到了同样的问题。由于数据是作为对象出现的。所以你可以这样做：
$view = view('template', (array) $object);
And in your view you use variables like
在您看来，您使用的变量是
{{ $id }}
