PHP PHP Arrays and Control Structures PHP Arrays Associative Quiz

I don't understand why the answer would be "0"

The question asks "What is the KEY of the fourth element?"

The KEY should be either "May or "April" depending on what you mean by "fourth element." If using the default index, then the answer should be "May" but if it's asking about the fourth KEY name down on the list that's written, then you could say "April".

If the question is supposed to ask what the VALUE of the fourth key is, then I could understand that it is 0, but then the question is worded incorrectly.

If you do a print_r($myArray), or do a var_dump() you get the 4th one equal to zero. I'm pretty sure that since April didn't define a key value it was assigned the first available numeric value starting with zero:

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 )
