PHP simply encapsulates some common JS operations_PHP tutorial

In web programming, you should often use some common js operations, such as alert(). Usually, you write them when you encounter them. Inspired by the company, I simply wrote a class to automatically generate these js. The purpose is for convenience. A gadget that novices may like ^_^
