I don't understand this, I need a little help...

This is the question

while (__________($key, $val) =__________ ($learn)) { 
echo "$key => $val\n"; 
}

I don't know what to fill it with

Oh! and on that note I don't want to make another question on this but heres another problem on another quiz,

Problem :

The next loop we'll look at is a "for loop". for loops are the most complex loops in PHP because they use 
 ________expressions instead of just one.

Hi channonhall,

The first. Personally I have never used it, but it's good to know that they exist:)

<?php
while ( list($key, $val) = each($learn)) { 
    echo "$key => $val\n"; 
}
?>

And the Second is The next loop we'll look at is a "for loop". for loops are the most complex loops in PHP because they use three expressions instead of just one. Hope it helps:)

Yea, when I first encoutered that second question I though "multiple expressions" was the answer:)
