What are the different approaches to checking if a form submit button has been pressed in PHP to execute specific actions?

To check if a form submit button has been pressed in PHP to execute specific actions, you can use the `isset()` function to determine if the form data has been submitted. You can then use an `if` statement to check if the submit button was clicked based on its name attribute. 

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

<form method="post">
    <input type="submit" name="submit_button" value="Submit">
</form>
