How can you differentiate between a button click and a page reload to trigger specific actions in PHP?

When a button is clicked, it typically triggers a specific action in PHP, while a page reload may be used for other purposes. To differentiate between the two, you can use a hidden input field in your form that is only present when the button is clicked. You can then check for the presence of this hidden input field in your PHP code to determine if the button was clicked or if the page was reloaded. 

<?php
if(isset($_POST['button_clicked'])) {
    // Action to perform when the button is clicked
    echo "Button clicked!";
} else {
    // Action to perform when the page is reloaded
    echo "Page reloaded!";
}
?>

<form method="post">
    <input type="hidden" name="button_clicked" value="1">
    <button type="submit">Click me!</button>
</form>
