PHP: Browser go back a page

I want for something like this:

<?php
if($something)
    header('Location:javascript:history.go(-2)');
?>

but header('Location:javascript:history.go(-2)'); doesn't work. Any alternatives?

I don't know the page the user was just on, so I can't hardcode the url.

From your point of view, i think you might be looking for something like this:

<html><head></head><body>
<?php
if($something){
?>
<script type="text/javascript">
window.history.go(-2);
</script>
<?php
}
?>
</body></html>

As long as they got there by a link you could use

header("Location: " . $_SERVER['HTTP_REFERER']);

You can't use the javascript: pseudo protocol in a Location HTTP header. In fact, you really shouldn't be using it at all.

Instead, send the whole URL to the page you want the user to go back to via the Location HTTP header (if you can) or you could echo the history.back() though I highly discourage that you do.

As a side note, always exit after sending the Location HTTP header. User agents don't have to follow it.
