That question probably needs more explanation--how to answer it is not that very obvious until you check the teacher's notes from the previous video:

Documentation

  • each: returns the current key and value pair from an array and advance the array cursor.
  • list: assigns variables as if they were an array.

Additional Examples

//increment before evaluating the $count variable
$count=0;
while ((list($key, $val) = each($todo)) && (++$count <= 2)) {
    echo "$key => $val\n";
}

//increment after evaluating the $count variable
$count=1;
while ((list($key, $val) = each($todo)) && ($count++ <= 2)) {
    echo "$key => $val\n";
}
