Quiz Question - Possible Typo

I believe there is a typo regarding one of the quiz questions.

It begins with:
I want to output this: 19801985 

<?php
$movies[] = array(
        "title" => "The Empire Strikes Back",
        "year" => 1980
    );

$movies[] = array(
        "title" => "Back to the Future",
        "year" => 1985
    );

foreach($movies as ????) {
    echo $item["year"];
}

?>

And gives the following as possible answers:
A. There's no variable name that would produce this output.
B. $movies
C. $movie
D. $item

I selected A rather than D thinking it was a trick question, because even if you used $item for the value in the foreach loop, you'd never get the output of '19801985.'

EDIT: I realized now I wasn't paying enough attention to the output value as a combination of two years. Silly me.

Hi

The foreach loop takes the movies array, then with each iteration the next element is assigned to ????. In this case $item

So in this instance the first loop/iteration takes 'The Empire strikes back' and defines it as $item echoing out the "year".

The next iteration then takes 'Back to the Future' and defines it as $item similarly echoing out the "year".

This is done without adding any spaces etc resulting in 19801985.

bit of light reading - may give a better explanation

Hope this explains it

Great explanation. I definitely just didn't pay enough attention, and can't delete my post now that I caught my mistake. But thanks for your answer. =)
