Apache的一个错误:[error] an unknown filter was not added: PHP

在apache的日志里经常看到这个错误:

[Fri Oct 08 14:49:18 2004] [error] an unknown filter was not added: php
[Fri Oct 08 14:49:18 2004] [error] an unknown filter was not added: php
[Fri Oct 08 14:49:20 2004] [error] an unknown filter was not added: php
[Fri Oct 08 14:49:20 2004] [error] an unknown filter was not added: php
[Fri Oct 08 14:49:40 2004] [error] an unknown filter was not added: php

自己的apache的版本是:
[root@eygle logs]# apachectl -v
Server version: Apache/2.0.49
Server built: Jun 15 2004 16:55:22

还是自己的经验不够，刚才查了一下，找到了答案:

Hi,

I have re-installed PHP as a DSO module on Apache 2.0.44 and I am unable
to use the new filter options. In v4.3.1 I could use the following:

<Files *.php>
       SetOutputFilter PHP
       SetInputFilter PHP
</Files>

<Files *.phps>
       SetOutputFilter PHP
       SetInputFilter PHP
</Files>

When I use this I am prompted to download the script and I get the
following in my error log:

[error] an unknown filter was not added: PHP

However if I use the older formatting with 4.3.2RC1 all works well:

AddType application/x-httpd-php .php
AddType application/x-httpd-php-source .phps

Is this a bug, or have I missed some documentation that tells me this is
no longer included?

Thanks.

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

Since 4.3.2RC the default Apache 2 sapi is the apache2handler and is no
longer filter based. Therefor you should use
AddType application/x-httpd-php .php
AddType application/x-httpd-php-source .phps

and not

<Files *.php>
       SetOutputFilter PHP
       SetInputFilter PHP
</Files>

If you do want to use the old filter sapi, you need to use
--with-apxs2filter option.
