What are the best practices for handling and organizing arrays in PHP to avoid confusion and errors?

When working with arrays in PHP, it is important to follow best practices to avoid confusion and errors. One way to do this is by properly organizing and structuring your arrays to make them easy to understand and maintain. This can be achieved by using meaningful keys for associative arrays, properly documenting the structure of multi-dimensional arrays, and using built-in functions like array_map() and array_filter() to manipulate arrays efficiently. 

// Example of organizing and structuring an associative array
$user = [
    'name' => 'John Doe',
    'email' => 'john.doe@example.com',
    'age' => 30
];

// Example of documenting the structure of a multi-dimensional array
$products = [
    [
        'name' => 'Product A',
        'price' => 50
    ],
    [
        'name' => 'Product B',
        'price' => 75
    ]
];

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