Download PHP from its web site http://php.net/
The download for Windows comes in two forms - installable setup EXE and ZIP archive.
The setup can be installed like any other software. For the ZIP archive format, you will find install.txt
with full instructions inside.
Before you can install PHP, you need to have a web server like Apache or IIS installed.
If you are using Ubuntu Linux, then just give the following commands to install Apache and PHP in a terminal window :
sudo apt-get install apache2
sudo apt-get install php5
sudo apt-get install libapache2-mod-php5
You can also use WAMP
, LAMP, EasyPHP
etc. to install Apache, PHP, mySQL, OpenSSL and many other packages without worrying about configuration.
As for learning PHP this is a good place to start : http://www.w3schools.com/php/default.asp
