Creating Hashes in Ruby
Arrays are not the only way to manage collections of variables. Another type of collection of variables is the hash, also called an associative array.

An Introduction to Loops in PHP
In PHP there are several different types of loops. Basically what a loop does is evaluate a statement as true or false. If it is true it executes some code and then alters the original statement and starts all over again by re-evaluating it. It continues to loop through the code like this until the statement becomes false.
