= Setting up PHP with Lighttpd =
== Introduction ==
Lighttpd supports PHP through both CGI and FastCGI. As the name suggests, FastCGI is preferable.
== Performance ==
In all our tests it has shown better performance than Apache 1.3.x + mod_php4. See http://www.lighttpd.net/benchmark/ for the results.
== Does it support opcode cachers like APC, TurckMM, XCache and friends? ==
YES! Even if their docs say they do not work in CGI. Under lighttpd, PHP is usually run as FastCGI which supports those opcode cachers like mod_php4 in Apache.

* http://eaccelerator.net/ (Successor of Turck mmCache)
* [/xcache XCache], [/xcache/wiki/GettingSource Installing XCache] (new, well tested, running with FastCGI)
(more to add)

= Installation =
'''Startingpoint:''' Lighttpd is already [wiki:TutorialInstallation installed and working]
First of all you need a PHP which is providing FastCGI support. Depending on your
distribution you might already have it:
=== ArchLinux ===
Read http://wiki.archlinux.org/index.php/Fastcgi_and_lighttpd
=== FreeBSD ===
{{{
#!ShellExample
$ cd /usr/ports/www/php-cgi
$ make install clean
}}}
=== Gentoo ===
Make sure the USE flag 'cgi' is enabled.
{{{
#!ShellExample
$ emerge -pv dev-lang/php
}}}
If it is not, then add it to make.conf or just to php.
{{{
#!ShellExample
# echo dev-lang/php cgi >> /etc/portage/package.use
}}}
Emerge php.
{{{
#!ShellExample
# emerge dev-lang/php
}}}
=== Debian / Ubuntu ===
Debian/Ubuntu provides a fastcgi enabled version.
{{{
#!ShellExample
# apt-get install php4-cgi
}}}
=== DragonFlyBSD ===
DragonFlyBSD uses pkgsrc to build it's packages. If you don't want IPV6 you need to use the deprecated USE_IPV6=NO.
{{{
#!ShellExample
# cd /usr/pkgsrc/www/php4
# bmake PKG_OPTIONS.php="fastcgi ssl" PKG_DEFAULT_OPTIONS="fastcgi ssl" install clean
}}}
=== Others ===
Download a source tar-ball from http://www.php.net/ and configure it with at least this settings:
{{{
#!ShellExample
$ ./configure \
--enable-fastcgi \
--enable-discard-path \
--enable-force-redirect
}}}
If you want to have the same PHP as you are using in a mod_php configuration somewhere else call
{{{
#!php
<?php phpinfo(); ?>
}}}
* copy the configure options from the output of the script
* remove the ``--with-apxs`` and ``--with-apxs2`` options
* add the three options from above.
Build PHP now by callings ``make`` and ``make install`` and see if you can find a php binary which is responding:
{{{
#!ShellExample
$ php -v
PHP 5.0.3 (cgi-fcgi) (built: Dec 21 2004 12:59:18)
Copyright (c) 1997-2004 The PHP Group
Zend Engine v2.0.3, Copyright (c) 1998-2004 Zend Technologies
with eAccelerator v0.9.3, Copyright (c) 2004-2005 eAccelerator, by eAccelerator
}}}
or something like this. The ``(cgi-fcgi)`` is the important part. The binary might also be called ``php-cgi``. ``php-cgi`` or if
so do something like php-cgi -v to see the (cgi-fcgi) banner.
{{{
#!ShellExample
$ php-cgi -v
PHP 4.4.2 (cgi-fcgi) (built: Jul 21 2006 15:45:58)
Copyright (c) 1997-2006 The PHP Group
Zend Engine v1.3.0, Copyright (c) 1998-2004 Zend Technologies
}}}
If you still can't find it follow this hint:
{{{
#!ShellExample
$ ls sapi/cgi/php
}}}
== Configuration ==
Add this line:
{{{
cgi.fix_pathinfo = 1
}}}
to you ``php.ini``. And make sure mod_fastcgi is loaded:
{{{
server.modules = (
"mod_fastcgi",
)
}}}
Then add this basic section to you ``lighttpd.conf``:
{{{
fastcgi.server = ( ".php" => ((
"bin-path" => "/path/to/php-cgi",
"socket" => "/tmp/php.socket",
)))
}}}
A little bit more advance is this setting which tries the tune some more options. If you need PATH_INFO the broken-scriptfilename is
for you.
{{{
fastcgi.server = ( ".php" => ((
"bin-path" => "/path/to/php-cgi",
"socket" => "/tmp/php.socket",
"max-procs" => 2,
"bin-environment" => (
"PHP_FCGI_CHILDREN" => "16",
"PHP_FCGI_MAX_REQUESTS" => "10000"
),
"bin-copy-environment" => (
"PATH", "SHELL", "USER"
),
"broken-scriptfilename" => "enable"
)))
}}}
If you're using any php opcode cacher, it is important to keep '''"max-procs" => 2''' low (1 or 2), unless you want to eat up so much memory.
Please read the configuration section for more background
* http://www.lighttpd.net/documentation/configuration.html
* http://www.lighttpd.net/documentation/fastcgi.html
and use
http://trac.lighttpd.net/trac/file/branches/lighttpd-1.3.x/doc/lighttpd.conf
as starting point for the configuration.
== Per directory PHP Config ==
If you're used to use Apache .htaccess files to set PHP options for each directory, see HowToPhpHtaccess :
''When using a cgi version of php (plain old cgi or fast-cgi) apache can't pass
any php settings from htaccess files it parses. This can be solved by giving
each user it's own php.ini file, but I didn't like that solution.
This extension parses these configuration files (in most cases .htaccess) and
changes the settings. It will search all directories for a configuration file
from the docroot until the directory where the request scripts is found.''
