Understanding Functions
A function is a named block of code that performs a specific task and can be executed whenever it is called.
Functions are a fundamental building block in PHP programming. By using functions, you organize your code into logical sections, making it easier to read, maintain, and reuse. This approach helps you avoid repeating code and reduces errors. In PHP, defining and calling functions is straightforward, and you will use them frequently as your programs grow in complexity.
