Apache 1.3.x doesn't support multiple filters over one file. You can't parse the output of a PHP file through SSI. (Apache 2.x can do that)
Are you sure that isn't the case?

No feedback. Closing.

Apache 1.3.23, php 4.1.2, HP-UX 10.20 and Linux (RedHat 7.1)

I have the same problem. I want to have both PHP and SSI
working on my server. I don't want to use PHP to generate SSI, I just want to use both PHP and SSI separately
for different things.

I have tried various configurations, but when I use 
'php_value include_path ".:/path/htdocs/php-mal"' anywhere
in my httpd.conf SSI just stops working. The server outputs
the SSI file unparsed. A typical configuration example 
looks like this:

 <Directory "/path/htdocs">
    Options IncludesNOEXEC FollowSymLinks
    XBitHack full
    php_value include_path ".:/path/htdocs/php-mal"
 </Directory>

I have tried to move php_value around, but this does
not help.

If I set the include_path in php.ini everything works 
as expected and I can use both PHP and SSI. But I _really_
need to assign a different include_path for php for each
of my virtual web-servers, and I need both PHP and SSI.

I have verified this behaviour both on a HP-UX server with 
several virtual hosts, and on a Linux server without 
virtual hosts, both running Apache 1.3.23 and php 4.1.2.

The problem reported at 
<URL:http://marc.theaimsgroup.com/?l=apache-httpd-users&m=101233512816689&w=2> might be related.

I would be really grateful if someone could try to 
reprocuce this error, and even more grateful for a
solution. But I have not even been able to find out if
this error is caused by php, mod_include or something
in the apache core.

What more could I do to help you solve this problem?

This seems to be a real problem and not solved, so I'm
reopening

Please try using this CVS snapshot:

  http://snaps.php.net/php4-latest.tar.gz
 
For Windows:
 
  http://snaps.php.net/win32/php4-win32-latest.zip

There was some xbithack related fix recently..please try the snapshot.

I have tested PHP 4.2.3 today, and the problem seems to be
solved. I am able to assign different include_paths on two
virtual servers, and SSI still works.

Thank you, this was a _really_ annoying bug.
