DevShed shares some basic PHP knowledge today with this new tutorial, an introduction to functions in PHP. This time, they're specifically focusing on custom function creation.
If you're looking for a way to save time when you program, look no further. Creating functions lets you reuse code that you've used before without having to rewrite the whole thing.
This will save you time and make programming easier, especially as websites become more complex. Another advantage of a function is that it executes wherever and whenever you call it, in the same way that print() displays text.
They start off basic, defining what a "user defined function" is before moving on to arguments in their use. They include the method to define default values and how to return values once the function is through.
