totally stuck!

Question

hi I have to complete the PHP tutorial (and provide the certificate of completion) as part of a class which has nothing to do with my major, so it's a understatement to say it's tough for me!! I've got to the very final quiz, am on question 4/6 and I haven't got enough points left to unlock any more hints! Can anyone assist?

"Fill in the blanks to define the Guitarist class that implements the MusicianInterface. Call the play() method on the Guitarist object."

________ MusicianInterface {
public function play();
}
class Guitarist ________ MusicianInterface {
public function play() {
echo "La La La";
}
}
$obj = new Guitarist();
$obj-> ______;

Answer 3

@Hatsy Rei I'm doing a course in digital instructional/learning design, which requires us just to have basic understanding of html, css, js and now php. I'm not a programmer and don't intend to become one.
I went through the course from the beginning (you can't skip quiz slides or levels if I'm not mistaken) but towards the end I needed a lot of help and used up all my credit.
I've began the tutorials on html, css and js, and although the start is always well adapted to beginners, after a while the level is just too difficult for me personally.

Answer 4

I'm more concerned about this class which requires you to submit a Sololearn PHP certificate, which has nothing for do with your major. (What's your major tho)

Anyway, the tutorials are supposed to be optimized for beginners who have no prior experience in programming. If you went through the course without skipping any slides, you might have been able to save a few unlocks. >.>

Answer 5

Fortuna D'Uva Blondeau I see. Maybe you were burning through the tutorials a little too quick (?), but that is understandable given your situation. I too fail to see why PHP is required if you don't intend to become a programmer (especially when JS is already introduced in the course you take).
