[PHP-WIN] Timed redirection

[Jim MacDiarmid]

Is there a way to programmatically add timed redirection to a page?  I have
a page with a form on it.  Once it's submitted and the data is updated in
the database correctly, I'd like to present a status page then wait for say
3 seconds before redirecting them to some other URL. 
 
I know you can do this with window.location = 'targetURL' but not sure how
to add it.  I was thinking that it might have to be added to the header, but
I'm using the same header template for each page. 
 
Any ideas?
 
TIA,
 
Jim
