Got this question wrong and want to know why?

so this was a multiple choice question. I pick it will return an error but I was wrong. Then after I got it wrong I thought the answer might be the last year on there but not sure.

Quiz Question 2 of 8 What year will this block of PHP code display?

<?php

$movies[] = array(

        "title" => "Star Wars",

        "year" => 1977

    );

$movies[] = array(

        "title" => "The Empire Strikes Back",

        "year" => 1980

    );

$movies[] = array(

        "title" => "Return of the Jedi",

        "year" => 1983

    );

echo $movies[1]["year"];

?>

echo $movies[1]["year"];

The code above is looking for the entry in the $movies array at index 1. PHP arrays begin at index 0, so you'll want to look at the second entry in the $movies array.

 $movies[] =

This pushes (or adds) data to the array, placing it at the bottom of the 'stack', with index 0 being the top of the stack. The second time data is pushed onto the $movies array is when the associative array with title "The Empire Strikes Back" is added:

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

The question is looking for the year value in that array, so the answer is 1980.
