What best practices can be followed to improve the readability and efficiency of PHP code when dealing with multidimensional arrays and loops?

When dealing with multidimensional arrays and loops in PHP, it is important to follow best practices to improve readability and efficiency. One way to achieve this is by using meaningful variable names and properly indenting the code to make it easier to follow. Additionally, breaking down complex loops into smaller, more manageable functions can help improve the overall structure of the code. 

// Example of improving readability and efficiency of PHP code with multidimensional arrays and loops

// Original code
foreach ($users as $user) {
    foreach ($user['orders'] as $order) {
        // Process order
    }
}

// Improved code
function processOrders($user) {
    foreach ($user['orders'] as $order) {
        // Process order
    }
}

foreach ($users as $user) {
    processOrders($user);
}
