How can PHP arrays be properly set up and manipulated to store user units and parent-user relationships for efficient calculations?

To properly set up and manipulate PHP arrays to store user units and parent-user relationships for efficient calculations, you can use a multidimensional array structure. Each user can be represented as an array with their units and parent-user relationship. You can then iterate through the array to perform calculations efficiently. 

// Sample array structure to store user units and parent-user relationships
$users = [
    [
        'name' => 'User A',
        'units' => 50,
        'parent' => 'Admin'
    ],
    [
        'name' => 'User B',
        'units' => 30,
        'parent' => 'User A'
    ],
    // Add more users as needed
];

// Iterate through the array to perform calculations
foreach($users as $user) {
    // Perform calculations based on user units and parent-user relationship
    echo $user['name'] . ' has ' . $user['units'] . ' units.' . PHP_EOL;
}
