Are there best practices for handling data manipulation and display in PHP scripts?

When handling data manipulation and display in PHP scripts, it is important to follow best practices to ensure efficiency, security, and maintainability. One common practice is to separate data manipulation logic from display logic by using functions or classes. Additionally, sanitizing user input to prevent SQL injection attacks and validating data before processing are crucial steps to take. 

// Example of separating data manipulation and display in PHP script

// Data manipulation logic
function getDataFromDatabase($id) {
    // Query database to fetch data based on ID
    // Return the data fetched
}

// Display logic
$id = $_GET['id']; // Assume this is user input
$data = getDataFromDatabase($id);

// Display the data
echo "<h1>{$data['title']}</h1>";
echo "<p>{$data['description']}</p>";
