Redirect IE8 users to another page

Question

I am implementing a website with Wordpress, but my website is not supported in Internet Explorer 8.

Is there any code I can use so that any IE8 users will be redirected to another page?

Answer 1

I know you specified PHP, but here's a HTML/JS solution:

<!--[if IE]>
    <script type="text/javascript">
        window.location = "http://www.google.com/";
    </script>
<![endif]-->

Taken from this answer.

If you specifically only want to redirect IE 8 users, change <!--[if IE]> to <!--[if IE 8]>.
