Bummer! Unfortunately, that answer is incorrect

How is this answer 0, I thought it was May, since the I counted it as the 4th => as the key?

Try run this code, if you have setup php locally, and see the output, I have anyway put the output

<?php

$myArray = array("January" => "Winter", "February" => "Winter", "March" => "Spring", "April", "May" => "Spring", "June" => "Summer", "July" => "Summer", "August" => "Summer", "September" => "Fall", "October" => "Fall", "November" => "Fall", "December" => "Winter"); 

echo "<pre>";
print_r($myArray);
echo "</pre>";

//the below would be the output you get, if you run it in a localhost

/*Array
(
    [January] => Winter
    [February] => Winter
    [March] => Spring
    [0] => April
    [May] => Spring
    [June] => Summer
    [July] => Summer
    [August] => Summer
    [September] => Fall
    [October] => Fall
    [November] => Fall
    [December] => Winter
)*/

//just to get more confidence, take 2 more keys out to see, what would be the keys represent
//here am taking the July out, and December out.
//for that the code would be as below

$myArray = array("January" => "Winter", "February" => "Winter", "March" => "Spring", "April", "May" => "Spring", "June" => "Summer", "Summer", "August" => "Summer", "September" => "Fall", "October" => "Fall", "November" => "Fall", "Winter"); 

//for the right above, you get the, below answer.

/*Array
(
    [January] => Winter
    [February] => Winter
    [March] => Spring
    [0] => April
    [May] => Spring
    [June] => Summer
    [1] => Summer
    [August] => Summer
    [September] => Fall
    [October] => Fall
    [November] => Fall
    [2] => Winter
)*/

//what confirms here, when you have an array, with the absence of a key, the first absent one
//will take 0 for key, as arrays are programmed to start from 0, and then blanks will be
//in ascending order.

?>
