This bug has been fixed in CVS.
In case this was a PHP problem, snapshots of the sources are packaged
every three hours; this change will be in the next snapshot. You can
grab the snapshot at http://snaps.php.net/.
In case this was a documentation problem, the fix will show up soon at
http://www.php.net/manual/.
In case this was a PHP.net website problem, the change will show
up on the PHP.net site and on the mirror sites in short time.
Thank you for the report, and for helping us make PHP better.

The error occurs on Linux, too. A customer reported it and it can
nicely be reproduced with
<?php
ob_start("ob_gzhandler");
?>
which yields the warning visible under

If I use ob_start("ob_gzhandler") function I get an error message: "PHP
Warning: ob_gzhandler() [<a
href='http://www.php.net/ref.outcontrol'>ref.outcontrol</a>]: output
handler 'ob_gzhandler' cannot be used twice in c:\web\test.php3 on line
11". The same script runs fine on 4.2.3. Interestingly, on version
4.3.0 ob_get_level() returns 2 and on 4.2.3 the return value is 1. I'm
using Windows 2000 Server/IIS5. PHP is configured in CGI mode.
Here's the script:
//---start---
<%
ob_start("ob_gzhandler");
%>
<html>
<body>
<h3>This is a test. ob_get_level: <% echo ob_get_level(); %></h3>
</body>
</html>
<%
if(ob_get_level()){
ob_end_flush();
}
%>
//---end---
And here's the essential configurations from the 'php.ini' file:
output_buffering = 4096
output_handler =
zlib.output_compression = Off
implicit_flush = Off
unserialize_callback_func=
allow_call_time_pass_reference = Off
If I set "output_handler = ob_gzhandler" and remove the
ob_start("ob_gzhandler") from the script it's working on 4.3.0 as well.
However, this way the compression is always on and I can't determine
myself when to use it.
