What are the best practices for implementing buttons in PHP scripts to avoid script errors or unexpected behavior?

When implementing buttons in PHP scripts, it is important to use proper form submission methods to avoid script errors or unexpected behavior. One common practice is to use a conditional check to determine if the form has been submitted before processing the button action. This helps prevent the script from running unnecessary code when the button is not clicked. 

<?php
if(isset($_POST['submit_button'])) {
    // Process button action here
    echo "Button clicked!";
}
?>

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