How can PHP developers differentiate between different submit buttons in a form submission for processing different actions?

To differentiate between different submit buttons in a form submission for processing different actions, PHP developers can assign a unique name to each submit button and check which one was clicked using an if statement in the PHP script that processes the form submission. 

if(isset($_POST['submit_button1'])){
    // Code to process action for submit_button1
} elseif(isset($_POST['submit_button2'])){
    // Code to process action for submit_button2
}
