Merge row data from two 2d arrays related by first level keys

How I can merge/push one array to another to specific keys? Here are my arrays:

// Array 1
Array
(
    [1] => Array
        (
            [name] => test
        )
)

// Array 2
Array
(
    [1] => Array
        (
            [age] => 25
        )
)

I want this result:

Array
(
    [1] => Array
        (
            [name] => test
            [age] => 25
        )
)
Solution 
  • $arr = [ 1 => [ "name" => "Test" ] ];
$arr2 = [ 1 => [ "age" => 25 ] ];

foreach ($arr as $key => $value) {
     if (isset($arr2[$key])) {
        $arr[$key] = array_merge($value,$arr2[$key]);
     }
}

print_r($arr);
