Welcome back! After exploring equality and inequality operators, it’s time to enhance our decision-making skills further with the elseif statement. In addition to making basic decisions with if and else, the elseif statement allows us to evaluate multiple conditions one after another. This lesson will help you write more nuanced and controlled responses in your code.

In this lesson, you’ll extend your decision-making repertoire with the elseif statement. Specifically, you’ll learn to:

• Evaluate multiple conditions sequentially.
• Write complex decision structures for various scenarios.
• Enhance code readability and maintainability with clear conditional logic.

For example, by the end of this lesson, you'll be able to write code that gauges oxygen levels for a spacewalk, similar to this:

Mastering the elseif statement enables you to handle more complex decisions and improve the efficiency of your programs. Whether it’s setting different states in a game, handling various user inputs, or managing different operational modes, elseif helps you craft fine-tuned logic. Having multiple conditions in check makes your program more robust and responsive to varying scenarios.

That sounds exciting, doesn't it? Let's get started and see how elseif will elevate your decision-making skills in PHP.
