Using PHP I would like to force the browser to refresh all pages (frames) in the frameset, as if the user had pressed the F5 button.
When I use
header("Location: frameset.php");
it reloads the whole frameset into one frame.
Yes, stay away from frames if at all possible. PHP can't really do this using a header redirect, you would have to use javascript to target the parent
frame and reload that. So something like:
<script type="text/javascript">
parent.location.reload();
</script>
