How to assign a value17 to the property number of the object $checker and what condition should i put for echo is|is not

This is the problem statement 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.)

palprimes.php
<?php
require_once("class.palprimechecker.php");




$checker = new PalprimeChecker();
$checker->number()=17;
echo "The number" . " $checker->number()";
echo "(is|is not)";
echo " a palprime.";

?>

Hello! Your are doing great so far!

The only problem I see so far in this challenger is that you are treating the 'number' property like a method.

Methods are like functions in that they require those parenthesis you have there after 'number'. Number in this objects's case is not a method.

set properties like so:

<?php
$object = new Object();
$object->property = 'foo'; 
?>

further, if your going to concatenate the value of number, it should not be in quotes.

Thnx for ur help

            <p>
$checker = new PalprimeChecker();

$checker->number = 17;


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

?></p>

           Would some mind taking a look. I don't get why this doesn't work. It is most probably something stupid

The error i get is the following

PHP Catchable fatal error: Object of class PalprimeChecker could not be converted to string in palprimes.php on line 9

But im not sure whats happening
