At times, we will want to achieve different outcomes based on the state of our data within a script. This behavior is known as control flow and uses conditional statements and loops that allow us to execute our code in a desired fashion.

In this lesson, we’ll look at

• if, else, and elseif statements
• switch statements
• for and foreach loops
• while and do…while and do…until loops
• break and continue commands

Using the correct form of control flow will help create scripts with different behaviors that are easy to understand and improve upon.
