What tools or methods can be used to maintain an overview of the entire PHP script while working on individual components?

When working on individual components of a PHP script, it can be challenging to maintain an overview of the entire script. One way to address this issue is by using code commenting to provide a high-level summary of each section of the script. Another method is to break the script into smaller, more manageable files and use include or require statements to bring them together. Additionally, using version control systems like Git can help track changes and provide a history of the script's evolution. 

// Example of using code commenting to provide a high-level summary
// of each section of the PHP script

// Section 1: Database connection
$db_host = 'localhost';
$db_user = 'username';
$db_pass = 'password';
$db_name = 'database';

// Section 2: Query database for user data
$query = "SELECT * FROM users WHERE id = 1";
$result = mysqli_query($db_connection, $query);

// Section 3: Display user data
while ($row = mysqli_fetch_assoc($result)) {
    echo "User ID: " . $row['id'] . "<br>";
    echo "User Name: " . $row['name'] . "<br>";
}
