Yii

Yii is a special kind of computer helper that helps people create websites. It is like a big box of Legos that you can use to build things.

With Yii, you don't have to start from scratch or build everything from scratch. Instead, you can use pieces of code that have already been made by other people to save time. It is kind of like using pre-made pieces to build a LEGO castle instead of starting with just a pile of pieces.

Yii is also very smart and efficient. It helps computer programs run faster and more smoothly, kind of like how your parents help you with math homework so you can finish it faster and move onto playing.

Overall, Yii is a helpful tool for building websites by using pre-made code to make it faster and easier, and it also helps websites run faster and better.
