What are the advantages of adding a unique identifier like server_id to each element in a multidimensional array in PHP?

Adding a unique identifier like server_id to each element in a multidimensional array in PHP can be advantageous when you need to uniquely identify and access specific elements within the array. This can be useful for tasks such as updating or deleting specific elements, or for tracking and managing data in a more organized manner.

<?php
// Sample multidimensional array with server_id added to each element
$server_data = [
    ['server_id' => 1, 'name' => 'Server A', 'status' => 'online'],
    ['server_id' => 2, 'name' => 'Server B', 'status' => 'offline'],
    ['server_id' => 3, 'name' => 'Server C', 'status' => 'online']
];

// Accessing a specific element using server_id
$server_id_to_find = 2;
foreach($server_data as $server){
    if($server['server_id'] == $server_id_to_find){
        echo "Server Name: " . $server['name'] . ", Status: " . $server['status'];
        break;
    }
}
?>
