How to handle form data with php?

Handling form data is a fundamental task in web development with PHP. You typically use the `$_GET` or `$_POST` superglobals based on the method attribute of your form.

Example:

  $name = $_POST['name'];
  $email = $_POST['email'];
  

Solution:

Always validate and sanitize form data before using it to avoid security issues:

  $name = filter_input(INPUT_POST, 'name', FILTER_SANITIZE_STRING);
  $email = filter_input(INPUT_POST, 'email', FILTER_VALIDATE_EMAIL);
