Code to be compiled in Raspberry Pi terminal:

git clone git://git.drogon.net/wiringPi
cd wiringPi
git pull origin
cd wiringPi ./build

Now test wiringPi installation with

cd wiringPi ./build

sudo apt-get update
sudo apt-get install apache2 apache2-doc apache2-utils
sudo apt-get install libapache2-mod-php5 php5 php-pear php5-xcache
cd /var/www/ sudo nano switch.php

In nano window paste this code:

$output = shell_exec('gpio mode '.$_GET['pin'].' out');
$output = shell_exec('gpio write '.$_GET['pin'].' '.$_GET['switch']);
echo $_GET['status'];
$output = shell_exec('gpio read 8');
echo "GPIO 2:".$output;
$output = shell_exec('gpio read 9');
echo "GPIO 3:".$output;
$output = shell_exec('gpio read 7');
echo "GPIO 4:".$output;
$output = shell_exec('gpio read 11');
