What are some best practices for handling button actions in PHP to ensure smooth functionality?

When handling button actions in PHP, it is important to use conditional statements to check which button was clicked and perform the corresponding action. This can be achieved by using the isset() function to determine if a specific button was clicked. By properly structuring your PHP code to handle button actions, you can ensure smooth functionality and improve the overall user experience. 

<?php
if(isset($_POST['submit_button'])) {
    // Code to execute when submit button is clicked
}

if(isset($_POST['cancel_button'])) {
    // Code to execute when cancel button is clicked
}

// HTML form with buttons
echo '<form method="post">';
echo '<input type="submit" name="submit_button" value="Submit">';
echo '<input type="submit" name="cancel_button" value="Cancel">';
echo '</form>';
?>
