What are some best practices for integrating PHP with HTML buttons for user interaction?

When integrating PHP with HTML buttons for user interaction, it is best practice to use form submissions and handle the button click event using PHP. This allows for processing user input and performing actions based on the button clicked. By using PHP to handle the form submission, you can easily interact with databases, perform calculations, or execute other server-side tasks.

<?php
if(isset($_POST['submit'])){
    // Handle button click event here
    echo "Button clicked!";
}
?>

<form method="post">
    <button type="submit" name="submit">Click Me</button>
</form>
