Why is this not working? Exercise 4/4 isPalprime()

Code:

<?php

require_once('class.palprimechecker.php');

$checker = new PalprimeChecker;
$checker -> number = 17;


echo "The number " . $checker->number . " ";

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

?>

No idea what I am doing wrong! Someone help?

Thanks, James.

palprimes.php
<?php

require_once('class.palprimechecker.php');

$checker = new PalprimeChecker;
$checker -> number = 17;


echo "The number " . $checker->number . " ";

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

?>

Hey James,

Your code is correct, but I think you accidentally deleted one of the pre-loaded lines of code. It is the last echo statement after the if else conditional.

<?php

require_once('class.palprimechecker.php');

$checker = new PalprimeChecker;
$checker -> number = 17;


echo "The number " . $checker->number . " ";

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

echo " a palprime.";     //this line was missing in you code snippet. 

?>

Keep Coding! :)
