What do you think: is 16661 a palprime? Assign the number property of $checker a value of 16661. Be sure to refresh the

My code seems to be correct but its not passing. What can i do?


$checker = new PalprimeChecker();

$checker->number = 16661;

echo "The number " .$checker->number." ";
if ($checker->isPalprime()) {
   echo "is a palprime.";
} else {
   echo "is not a palprime.";


I think the only problem is that in the two echo statements you include the " a palprime" in each. I think they want that left as a separate echo after the condition.

You certainly do not need the exit statement. Maybe that gets checked?

<?php include('class.palprimechecker.php');

$checker=new PalprimeChecker(); $number=$checker->number=16661;

echo "The number ".$number." "; if($checker->isPalprime($number)) { echo "is a palprime"; } else { echo "is not a palprime"; }
