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);
