Are there any best practices for managing and manipulating arrays in PHP?

When managing and manipulating arrays in PHP, it is important to follow best practices to ensure efficient and effective code. Some best practices include using built-in array functions like array_map, array_filter, and array_reduce, avoiding unnecessary loops when possible, and properly handling edge cases such as empty arrays. 

// Example of using array_map to manipulate an array
$numbers = [1, 2, 3, 4, 5];
$squaredNumbers = array_map(function($num) {
    return $num * $num;
}, $numbers);

print_r($squaredNumbers);
