The code (from the Header() manual page)

header("Expires: Mon, 26 Jul 1997 05:00:00 GMT");
    // Date in the past
header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT");
    // always modified
header("Cache-Control: no-store, no-cache, must-revalidate");  
    // HTTP/1.1
header("Cache-Control: post-check=0, pre-check=0", false);
header("Pragma: no-cache");
    // HTTP/1.0

only outputs a single "Cache-control" - the second one.

It seems to me that the "replace" flag of sapi_header was never being checked. 

I've written a fix for this though as shown below. I hope this is right, and that it is useful to someone :-)
