Conditional Statements allow you to branch the path of execution in a script based on whether a single, or multiple conditions, evaluate to true or false. Put simply, they let you test things and perform various actions based on the results.

Frequently in PHP there are instances where you need to perform repetitive tasks, such as formatting data pulled from a database, sending out emails to a mailing list, or cycling through the contents of an array. Control Loops allow you to perform these tasks almost effortlessly.
