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.";

<?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!

echo "The number " + echo $checker;
to
echo "The number " . $checker;
The dot is the php concatinator.
