Required steps to store form data in session in PHP

  • First of all, start the PHP session with the help of the session_start() function.
  • We will get the form values from the request after submitting with the help of PHP $_POST[] global variable in the form of an array.
  • Now, we will store all the POST variables in a session array with the help of the $_SESSION[] global variable in the form of an array in PHP.
  • The form values will remain in session until we click the reset button.
  • After clicking the reset button, all the form values will be removed from the form fields with the help of the session_unset() function.

Complete Code:-

    //store the session data
	$_SESSION['username'] = $_POST['username'];
	$_SESSION['email'] = $_POST['email'];
	$_SESSION['phone_no'] = $_POST['phone_no'];
//reset the form data
