Forms, Arrays, and Get Variables

Sorry I just got it. as $a stands for the key it refers that as there are 2 values in the array they are being assigned the key 0 and then 1 accordingly.

Now I don't understand a similar question which is:

<?php

$flavors = array("Cake Batter","Cookie Dough");

foreach ($flavors as $a => $b) {

    echo $b;

}

?>

I thought the answer would be "Cake batterCookie Dough" as i thought $b as is inside a foreach would give me the value of the 2 items inside the array, but the answer was only Cake batter, why?

This doesn't look like the full code for the question. I was certain their was an if statement around that question when I came to it...

Something along the lines of:

if($var < $total) {
    // echo here
}

Because the use of the < (less than) is present, it will only output $b if it's less than the total. IF it was <= you would get both values.

I hope this was for the question I was thinking about.

Hi @Diego !

I'm sorry you're having trouble. I wish I could be of more help :( Would you be able to provide a link to the quiz or code challenge you're working on?

I'm reaching out to the Teaching team to see if they can help out too!

If you're still having trouble shoot me an email at help@teamtreehouse.com :)

Hi Elizabeth,

The link is http://teamtreehouse.com/library/programming-2/build-a-simple-php-application/integrating-with-paypal/forms-arrays-and-get-variables

And the question says exactly as follows:

<?php

$flavors = array("Cake Batter","Cookie Dough");

foreach ($flavors as $a => $b) {

    echo $b;

    exit;

}

?>

And the possible answers are:

• a) 01
• b) Cake Batter
• c) 0
• d) Cake BatterCookie Dough

The answer for the test is b) (which was Jonathan's answer and it would be correct as if he said there was a conditional, but there's none). That's why I thought the correct answer should be d) but it keeps saying it is wrong.

Hey Diego,

The exit command there makes a big difference. The exit command causes the program to stop executing immediately, without finishing all the code. (We've talked about the exit command in a couple of places when displaying values in the browser for testing.) In this case, we start in the foreach loop. We echo out the value for the first one, Cake Batter. Then, before we can loop through to the next flavor, the exit command causes the code to stop executing.

Does that help?

Oh now i get it. Thank you very much!

Wow, I am sorry I didnt spot that earlier Diego... I completely skimmed past the exit :(

Glad you are all set now though.
