What are the best practices for structuring PHP code to handle multiple forms in a single file, and how can functions be effectively utilized for this purpose?

When handling multiple forms in a single PHP file, it is best practice to use functions to encapsulate the logic for each form. This helps to keep the code organized and makes it easier to maintain and debug. By creating separate functions for each form, you can easily call the appropriate function based on the form submission. 

<?php

// Function to handle Form 1 submission
function handleForm1() {
    // Logic for processing Form 1 data
}

// Function to handle Form 2 submission
function handleForm2() {
    // Logic for processing Form 2 data
}

// Check which form was submitted
if(isset($_POST['form1_submit'])) {
    handleForm1();
} elseif(isset($_POST['form2_submit'])) {
    handleForm2();
}

?>
