	:In another section of this lab you created a basic ''phptest.php'' file and saw how the server executed the PHP code and turned it into an HTML page your browser could display. Because PHP offers an easy way to write web applications it powers much of the Internet. To prepare us for setting up some PHP applications in a future lab it will be helpful to know a little about how PHP scripts work. Read through the [http://www.w3schools.com/php/default.asp W3 Schools PHP Basics Tutorial] (PHP ~~Intro~~ through PHP ~~Superglobals~~) and try creating some PHP scripts on your own Linux server like the examples given in the tutorial pages to see if you can get them to run, try modifying them a little bit and see what the results are. There are many great Internet resources devoted to understanding how to do things with PHP so take some time to see how this language can be easily integrated in websites. You should definitely be familiar with editing PHP files to change variables, echo statements, etc. work which are all skills you'll need when installing PHP based website software.		:In another section of this lab you created a basic ''phptest.php'' file and saw how the server executed the PHP code and turned it into an HTML page your browser could display.
