Bagaimanakah saya boleh menggabungkan dua tatasusunan PHP dengan kunci yang sepadan ke dalam tatasusunan tunggal, mengekalkan pasangan nilai kunci daripada kedua-dua tatasusunan?

<code class="php">array(
    [
        "Camera1" => "192.168.101.71"
    ],
    [
        "Camera2" => "192.168.101.72"
    ],
    [
        "Camera3" => "192.168.101.74"
    ]
)</code>

<code class="php">array(
    [
        "Camera1" => "VT"
    ],
    [
        "Camera2" => "UB"
    ],
    [
        "Camera3" => "FX"
    ]
)</code>

<code class="php">$array1 = array(
    ["Camera1" => "192.168.101.71"],
    ["Camera2" => "192.168.101.72"],
    ["Camera3" => "192.168.101.74"],
);

$array2 = array(
    ["Camera1" => "VT"],
    ["Camera2" => "UB"],
    ["Camera3" => "FX"]
);

$results = array();

array_map(function($a, $b) use (&$results) {
    $key = current(array_keys($a));
    $a[$key] = array('ip' => $a[$key]);

    $key = current(array_keys($b));
    $b[$key] = array('name' => $b[$key]);
  
    $results += array_merge_recursive($a, $b);

}, $array1, $array2);

var_dump($results);</code>

array (size=3)
  'Camera1' => 
    array (size=2)
      'ip' => string '192.168.101.71' (length=14)
      'name' => string 'VT' (length=2)
  'Camera2' => 
    array (size=2)
      'ip' => string '192.168.101.72' (length=14)
      'name' => string 'UB' (length=2)
  'Camera3' => 
    array (size=2)
      'ip' => string '192.168.101.74' (length=14)
      'name' => string 'FX' (length=2)
