Description:
------------
I'm using PHP-script as part of the page by including it in some middle part of the page (e.g. after some HTML code) using Apache SSI directive <!--#include ... --> 

So when headers_sent() is called before any script output it returns FALSE instead of TRUE. Also, header() function called immideately after that does nothing and executes silently.

As I can understand, any HTML code send before SSI #include of script must set headers_sent() to TRUE.

I have no any errors suppressed on my php.ini file or by other control directives.

Reproduce code:
---------------
page.shtml file (simplified):
<html>
<body>
<!--#include vurtual="./script.php?$QUERY_STRING" -->
</body>
</html>

script.php file (simplified):
<?php
$location = "/some/path/";
if( headers_sent() ) {
	echo "<script language="JavaScript"> window.location.href = '" . $location . "'</sctipt>";
}
else {
	header('Location: '.$location);
	// execution goes HERE! And no any effect or error messages.
}
?>

Expected result:
----------------
<html>
<body>
<script language="JavaScript"> window.location.href = '/some/path/'; </sctipt>
</body>
</html>


Actual result:
--------------
<html>
<body>

</body>
</html>

what happends if you use CORRECT syntax ?

<!--#include virtual="./script.php?$QUERY_STRING" -->


NOT

<!--#include vurtual="./script.php?$QUERY_STRING" -->

It's just mistprint, excuse me. Of course, I'm using correct syntax in any working examples.

There is also must be </script> instead of </sctipt> printed above, but it doesn't matter, you may instert any code to that output.

"virtual" does subrequest, i.e. does almost the same as include("http://...").
No bug here.
