'foreach' Question - Final Quiz - Integrating w/ Paypal

In the:

PHP Dev Track> Building Simple PHP App> Integrating w/ Paypal> 'Final Quiz'

How is the answer to the Q below: 'Cake Batter' and not 'Cake BatterCookie Dough' ? 

<?php

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

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

    echo $b;

    exit;

}

?>

This makes no sense to me. I've spent about 3 hours of research and had to circle back through the quiz 4 times to determine this was the right answer. Still don't understand the rational. Could this be an error? Or am I just an idiot.

Thanks, Kyle

Kyle,

I don't remember the quiz, or the code a associated with section, but the reason PHP in the posted example only outputs 'Cake Batter' is because of the keyword 'exit'. Unlike the keyword 'break', which just stops the current loop, 'exit' actually stops the execution of the entire script. So, even though you have two values in the array to be looped over, the script stops execution after echoing the first value when it sees the exit keyword.

Here's a link to the PHP documentation on the keyword - http://www.php.net/exit.

Cheers, Ryan

Thanks Ryan!

I appreciate the quick response. Was pulling my hair out, literally.

Wasn't even looking at the 'exit. 'Forest through the trees', or something like that I guess.

Regards, Kyle

Sorry, just realized I never gave you your 'best answer cred' either.
