#Setting up PHP
## Use Flags
In order for PHP to be most useful, it should have as many of the modules installed as will be used. I recommend installing it using the FPM sapi, which manages php session spawning.
Here are some recommended flags:
`mysql utf8 threads -readline libssh2 -cgi fpm xcache suhosin postgres mysqlnd reflection session simplexml sockets spl pdo mbstring sqlite3 mysqli soap`
## PHP_TARGETS
The `PHP_TARGETS` setting in `/etc/make.conf` lets you select which versions of PHP to compile. If possible, I recommend always using the latest stable version.
As of the time this is written, php 5.3 is the latest version, so I would add this line to `/etc/make.conf`
`PHP_TARGETS="php5-3"`
As of this writing, PHP compiles with clang reliably.

# General Setup
## Install LLVM/Clang
Clang is a faster compiler than the default GCC. It produces binary as fast, or faster than GCC. To set up clang,
run `emerge llvm clang`
and add these to lines to the top of your `/etc/make.conf` file
CC=/usr/bin/clang
CXX=/usr/bin/clang++
If a package fails to compile with clang, you can comment out those lines, and recompile the package with GCC.
