About PHP
PHP handles data before it becomes XHTML.
It originally stood for Personal Home Page
created in 1994 by Rasmus Lerdorf.
A variable is best thought of as a container for data.
Once data has been stored in a variable as a value, it can be printed, saved to a database and even emailed.
An array is a collection of multiple values assembled into one overriding variable.
Cookies are like name tags. They are created on the user's machine so the server can remember the user.
