What is the difference between passing values through an iframe using $_GET and $_POST in PHP?

When passing values through an iframe using $_GET in PHP, the values are appended to the iframe URL and can be seen in the browser's address bar. On the other hand, when passing values through $_POST in PHP, the values are sent in the background and are not visible in the URL. Using $_POST is more secure as sensitive information is not exposed in the URL. 

<!-- Passing values through an iframe using $_GET -->
<iframe src="iframe.php?value=example"></iframe>

<!-- Passing values through an iframe using $_POST -->
<form action="iframe.php" method="post" target="iframe">
    <input type="hidden" name="value" value="example">
</form>
<iframe name="iframe"></iframe>
