Help With Php Functions

Question: PalprimeChecker objects have a property called number. This task has two parts. First, assign that property a value of 17. Second, remove the two hash signs (##) in the first echo statement and instead concatenate the value of this number property. (Be sure to preserve the space after the two hash signs by concatenating a space after the number.)

My Code:

include "class.palprimechecker.php";

$checker = new PalprimeChecker(17);

echo "The number " + echo $checker;

echo "(is|is not)";

echo " a palprime.";

Finally!

<?php

include("class.palprimechecker.php");

$checker = new PalprimeChecker();

$checker->number = 17;

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

?>

First you were setting the property incorrectly with

$checker = new PalprimeChecker(17);

instead of

$checker->number = 17;

second they wanted to echo $checker number by doing

echo $checker->number;

instead of 

echo $checker;

Whew I hit my head on the desk a few times with that one!

Change

echo "The number " + echo $checker;

to

echo "The number " . $checker;

The dot is the php concatinator.
