What is the correct way to handle form action in PHP to prevent redirection issues?

When handling form actions in PHP, it is important to prevent redirection issues by using conditional statements to check if the form has been submitted. This can be done by checking if the form data has been posted using the `$_SERVER['REQUEST_METHOD']` variable. By checking this variable, you can ensure that the form processing code is only executed when the form is submitted, preventing unnecessary redirections. 

if ($_SERVER['REQUEST_METHOD'] == 'POST') {
    // Form processing code here
    // This code will only execute when the form is submitted
}
