PDO - array_map返回键中的对象ID

Question

hey i have array with returned keys

$temp = $sth->fetchAll(PDO::FETCH_ASSOC);

my result looks like this:

[0] => [
    'id' = 11,
    'title' => 't1'
]

[1] => [
    'id' = 12,
    'title' => 't2'
]

if i want to return ids as key i call something like this:

$temp = array_map(function($v){return $v[0];}, $sth->fetchAll(PDO::FETCH_GROUP|PDO::FETCH_ASSOC));

and my resoult looks like this:

[11] => [
    'title' => 't1'
]

[12] => [
    'title' => 't2'
]

how to return array of objects by ID? when i do this i dont have methods in object...

$temp = array_map(function($v){return $v[0];}, $sth->fetchAll(PDO::FETCH_GROUP|PDO::FETCH_CLASS));

I will do a bit easier code like below:-

$fianl_array = array_combine(array_column($temp,'id'),$temp);

Reference:-

array_column()

array_combine()
