You can use php for other stuff and insert javascript into the page for the redirect.
For instance this is a page I did that redirects after showing the results of a contact form:
PHP Code:
<?php
bunch of php code here
<script Language="JavaScript">
<!--
var URL = "http://www.mysite.com"
var speed = 3000
function reload(){
location = URL
}
setTimeout("reload()",speed);
//-->
</script>
<p><strong>Redirecting in 3 seconds <br />
Click <a href="http://www.mysite.com">here</a> if you would not like to wait </strong></p>
<p> </p>
<?php
}
?>
var URL is the link you want to redirect to
var speed is how long it will take (ms, 3000=3 secs, 5000=5 secs, etc.)
