What are the differences between using method="post" and method="get" in PHP forms?

When submitting a form in PHP, the method attribute determines how the form data is sent to the server. Using method="post" sends the form data in the HTTP request body, which is more secure and allows for larger amounts of data to be sent. On the other hand, using method="get" appends the form data to the URL, making it visible in the browser's address bar and limiting the amount of data that can be sent.

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