Laravel Collection 对象数组到简单数组方法

Question

我为 $result 变量分配了这样的数组对象集合：

// below is the $result value i.e. output of print_r($result);
Illuminate\Support\Collection Object ( [items:protected] => Array ( [0] => stdClass Object ( [email] => [email protected] ) [1] => stdClass Object ( [email] => [email protected] ) [2] => stdClass Object ( [email] => [email protected] ) [3] => stdClass Object ( [email] => [email protected] ) [4] => stdClass Object ( [email] => [email protected] ) [5] => stdClass Object ( [email] => [email protected] ) ) ) 

为了将上面的内容转换为简单数组，我使用如下循环：

print_r($result);
$user_emails = array();
foreach ($result as $key => $value) {
    array_push($user_emails,$value->email);
}
print_r($user_emails); 

我得到的 $user_emails 值如下：

Array ( [0] => [email protected] [1] => [email protected] [2] => [email protected] [3] => [email protected] [4] => [email protected] [5] => [email protected] ) 

我想知道是否有更好更快的方法来实现我上面所做的事情，使用任何 laravel 集合方法。

Answer 1

你可以尝试一下：

$result->pluck('email')->all();

Answer 2

最后这对我有用：

$result->pluck('email')->toArray();
