This is the very first time you have witnessed PHP code in action.

There are a few take aways to this code.

• The php is embedded in an HTML document
• It can be handled in line with HTML
• It can store data and work with it in the document

Some things that are less apparent:

• The code is run server side, all the load is happening on the server.

Functions being used in this code:

rand – a random number generator. Rand can generate a random integer, and you can pass it a high and low value to work of off.
