In web development, I think many who here the term “interface” or who talk about “creating an interface” usually refer to how the page, site, or graphics will look.
And that’s completely normal because when the majority of outlets – presentations, news, articles, media, etc. – talk about the way something looks as it relates to technology, they always talk about its interface.
Not to mention, it is the correct term.
But when it comes to object-oriented programming, the idea of creating an interface is a bit different. Rather than referring to the way a program looks, you could say that it has more to do with how it functions.
Even that isn’t necessarily the proper definition, but it’s close enough. If you’re an experienced programmer, then you’re likely already familiar with this idea.
But if you’re someone who’s just getting into object-oriented programming (specifically using PHP in the context of WordPress), then maybe this will help when designing the architecture of your next project.
