Given the following question:
What does the following block of code output? <?php
$flavors = array("Cake Batter","Cookie Dough");
foreach ($flavors as $a => $b) {
echo $b;
exit;
}
?>
My assumption would have been that both values were stored in the $b working variable and therefore the echo command would print both flavors. Am I missing something here as to why cookie dough isn't echo'd?

You are correct, both values are stored in $b, however because you have exit; inside your foreach loop after the echo statement, only the first iteration (First Value) is echo'd.
If for example you removed the exit; you would then echo out Cake BatterCookie Dough and for $a 01.
Hope this helps.
