What best practices can be implemented to improve the readability and maintainability of PHP scripts, especially when dealing with complex data structures?

To improve the readability and maintainability of PHP scripts, especially when dealing with complex data structures, it is recommended to use meaningful variable names, properly indent the code, and add comments to explain the logic. Additionally, breaking down the code into smaller functions can make it easier to understand and maintain. 

// Example of using meaningful variable names, proper indentation, comments, and small functions

// Define a complex data structure
$users = [
    [
        'name' => 'John Doe',
        'age' => 30,
        'email' => 'john.doe@example.com'
    ],
    [
        'name' => 'Jane Smith',
        'age' => 25,
        'email' => 'jane.smith@example.com'
    ]
];

// Function to print user information
function printUser($user) {
    echo "Name: " . $user['name'] . "\n";
    echo "Age: " . $user['age'] . "\n";
    echo "Email: " . $user['email'] . "\n";
    echo "\n";
}

// Loop through users and print their information
foreach ($users as $user) {
    printUser($user);
}
