Stuck on PHP Objects Challenge

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.

Stuck on this assignment. Challenge 4 of 7

Anyone under this assignment??

include ('class.palprimechecker.php');

$checker = new palprimechecker();

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

?>

for the second part...i thought the answer was echo "The number " . $checker;

was correct but I cannot figure out the first part so I am unsure of the second as well.

Hey Justin,

In order to access an objects property, you'll need to use the arrow operator. 

$checker->number;

Hope this helps.

Still can't seem to figure it out...

so far i have this

include ('class.palprimechecker.php');

$checker = new palprimechecker(); $checker->number;

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

Sorry this should be easier to read include ('class.palprimechecker.php');

$checker = new palprimechecker();
$checker->number;

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

Now that you have access to that property, you'll need to assign it a value. As an example:

$obj->property = value;

nemanjasreckovic
nemanjasreckovic
8,784 Points
nemanjasreckovic
nemanjasreckovic
8,784 Points

this will work

<?php

include_once('class.palprimechecker.php');
$checker = new PalprimeChecker();

$checker->number = 12421;

echo "The number ". $checker->number;
if ($checker->isPalprime()) { echo "is"; } else {echo "is not";};
echo " a palprime.";

?>
