There are some basic functions that are used so often that you will find them in most programming languages. The syntax for these functions will change from language to language and sometimes the functionality will be slightly different, so it$$s good to know how to look these things up$.$

In the list below, you$$ll find of common PHP functions. I would like you to choose a function, strlen$()$do some research on it$,$ and then describe it in your discussion post with a real$-$world scenario where the function might be useful. Can you think of a way you might want to use it in your final project? Some key points that you can touch on about the functions are:

What does the function do$?$

How many parameters does the function take and what are they? Are any of them optional?

Does the function return anything, or does it modify any existing variables?

Are there any special cases where the function does something different?

Can you find a function that does something similar in JavaScript? Does it work any differently?

Come up with a scenario of how this function might be used in a real$-$world website. Do you think it is used often?
