PHP Object Oriented Programming #5: Interfaces

In tutorial 5 on Object Oriented PHP Programming, we look at interfaces. More specifically, we create a user interface with a public method greeting. We then create english and french users which are required to implement the greeting method. Using a utility class, we then dynamically call the greeting method.

In doing so, we also take a quick look at the popular Factory design pattern near the end of the tutorial.

Nice to see how you work through solving how to write the correct code.
That I think is a great lesson in itself, and one I don't consider tedious at all when watching your videos.
Thanks again.

I went on some PHP training about two weeks ago and I had a question about interface. I was not satisfied with the answer given. It seemed lacking so I went looking for it here on youtube and watched a couple more videos with the same empty explanation and went on until I found your video. This is exactly the kind of explanation that I was looking for. Thanks!

in this way we could create a multible language website. that's nice.
While defining every function in the interface it automaticly requires some functions.

For example:

$utility->title('english')

And in the english class it called something like: Webshop with brandname

Instead of just entering every single word in php. You should create an YML or XML or JSON file. So you can change the values through a user interface


* I prefer JSON. personal preference.

Thank you for the video, great and simple explanation. Could you please however clarify how the "User" parameter option is called in the Utility function? I though it was "instance of" but it's apparently not???

As cool as this this, I fail to see its usefulness. But I'm also not a developer so I guess there's also that.
