What is the best practice for opening a page in a different frame using a button in PHP?

To open a page in a different frame using a button in PHP, you can use JavaScript to target the frame and change its source URL when the button is clicked. This can be achieved by adding an onclick event to the button that calls a JavaScript function to set the src attribute of the frame element. 

<button onclick="openPageInFrame()">Open Page in Frame</button>
<iframe id="myFrame" src="defaultPage.php"></iframe>

<script>
function openPageInFrame() {
    document.getElementById("myFrame").src = "newPage.php";
}
</script>
