WordPress defines many useful functions. Rather than reinventing the wheel, you should take advantage of the core functions whenever possible. Of course, if the slick new plugin you are designing needs a better wheel, you are on your own, but at least you can take inspiration from the following functions.

Please check out the wp-docs mailing list to find out how you can contribute to this section. And it needs your help!.
