WHAT IS THIS?
|
||||
|
||||
It is an output filter for Apache 2.0.
|
||||
|
||||
HOW DOES IT WORK?
|
||||
|
||||
In Apache 2.0, you have handlers which generate content (like
|
||||
reading a script from disk). The content goes then through
|
||||
a chain of filters. PHP can be such a filter, so that it processes
|
||||
your script and hands the output to the next filter (which will
|
||||
usually cause a write to the network).
|
||||
|
||||
DOES IT WORK?
|
||||
|
||||
It is experimental as interfaces in Apache 2.0 might change in the
|
||||
future.
|
||||
|
||||
HOW TO INSTALL
|
||||
|
||||
Get the latest Apache 2.0 alpha or the CVS code and install it.
|
||||
|
||||
$ cd apache-2.x
|
||||
$ cd src
|
||||
$ ./configure --enable-so
|
||||
$ make install
|
||||
|
||||
For testing purposes, you might want to use --with-mpm=prefork.
|
||||
(Albeit PHP also works with threaded MPMs.)
|
||||
|
||||
Configure PHP 4:
|
||||
|
||||
$ cd php-4.x
|
||||
$ ./configure --with-apxs2=/path/to/apache-2.0/bin/apxs
|
||||
$ make install
|
||||
|
||||
APXS is currently still flaky, so edit conf/httpd.conf and change
|
||||
the LoadModule entry from libphp4.la to libphp4.so.
|
||||
|
||||
At the end of conf/httpd.conf, add:
|
||||
|
||||
<Files *.php>
|
||||
AddOutputFilter PHP
|
||||
</Files>
|
||||
|
||||
That's it. Now start bin/httpd.
|
||||
|
||||
If you want to debug Apache, set ONE_PROCESS in your environment
|
||||
(comparable to -X in Apache 1.3). We recommened the prefork MPM
|
||||
for debugging purposes.
