What are the best practices for structuring PHP scripts to avoid repetitive and chaotic code?

To avoid repetitive and chaotic code in PHP scripts, it is recommended to follow the principles of Don't Repeat Yourself (DRY) and Separation of Concerns. This involves breaking down the code into smaller, modular components, using functions and classes to encapsulate logic, and avoiding duplicate code by reusing functions and variables. 

// Example of structuring PHP script to avoid repetitive and chaotic code

// Define a function to handle common functionality
function processUserData($data) {
    // Code to process user data
}

// Main script logic
$userData1 = ['name' => 'Alice', 'age' => 25];
processUserData($userData1);

$userData2 = ['name' => 'Bob', 'age' => 30];
processUserData($userData2);
