What is the difference between using "get" and "post" methods in PHP forms?

When submitting a form in PHP, the main difference between using the "get" and "post" methods is how the form data is sent to the server. - When using the "get" method, the form data is appended to the URL as query parameters, which can be seen in the browser's address bar. This method is suitable for sending small amounts of data and is often used for search forms. - On the other hand, when using the "post" method, the form data is sent in the HTTP request body, making it more secure as it is not visible in the URL. This method is recommended for sending sensitive information like passwords. Here is an example of how to specify the method in a form using PHP:

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

To use the "post" method instead, simply change the method attribute to "post" in the form tag:

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