Hi Tommy,

Question is :

PalprimeChecker objects have a method called isPalprime(). This method does not receive any arguments. It returns true if the number property contains a palprime, and it returns false if the number property does not contain a palprime. (Tip: 17 is not a palprime.) Turn the second echo statement into a conditional that displays “is” or “is not” appropriately. The conditional should call the isPalprime method of the $checker object. If the isPalprime method returns true, then echo “is”; otherwise, echo “is not”.

My code so far

<?php

require_once ('class.palprimechecker.php');
$checker = new PalprimeChecker();
$checker->number = 17;



echo "The number" . $checker->number . " ";
echo "(is|is not)";
echo " a palprime.";

?>

I've tried everything I knew but no joy I know its a "if" statement and echoing out is not the problem its between the () I have the issue...

Thanks

Hey Craig,

Your condition should look like this:

if ($checher->isPalprime())

or more complete:

if ($checher->isPalprime()) {
    echo "is";
}
else {
    echo "is not";
}
