What is the difference between POST and GET methods in PHP forms?

The main difference between POST and GET methods in PHP forms is how data is sent to the server. GET method sends data through the URL, visible to users, while POST method sends data through the HTTP request body, keeping it hidden. It is recommended to use POST method for forms that submit sensitive information like passwords.

<form method="post" action="process_form.php">
    <!-- form fields go here -->
    <input type="submit" value="Submit">
</form>
