FreeBSD:php

This will install the PHP 5 base system on your FreeBSD machine from the ports tree, and clean up everything when it's done.

# cd /usr/ports/lang/php5/ && make install distclean

often you will need a php extension installed. In order to help the various people who are stuck like I was, here is a list of possible extensions you may need/want:

Initially my searches online led me to know I needed the session extension for php. As it wasn't intuitive to me, I manually added "--enable-session" to the Makefile in /usr/ports/lang/php5/. I was told this is the wrong approach, and it could affect me later. So there are two approaches from here. One way to find the two approaches:

# ( cd /usr/ports && make search key=pcre | grep Path: | grep php5 )
Path:   /usr/ports/devel/php5-pcre
Path:   /usr/ports/lang/php5-extensions
Path:   /usr/ports/www/horde-php5

so if I just want to install a single extension, it's probably found in /usr/ports/devel/php5-pcre or if I want to install several, I can install each individually, or go into the php extensions meta port

# cd /usr/ports/lang/php5-extensions && make config

will give me an ncurses based window to go through and pick the extensions I want. After that I can do

# make install distclean

as long as I'm still in the usr/ports/lang/php5-extensions directory.

Errors

Fatal error: Call to undefined function preg_match() in

This means you will want to install the pcre extension.
