PHP Build a Simple PHP Application Wrapping Up The Project Objects

i don't get it

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

  include('class.palprimechecker.php');

  $checker = new PalprimeChecker();
  PalprimeChecker[0] = 17;


echo "The number" . PalprimeChecker[0];
echo "(is|is not)";
echo " a palprime.";

?>

<?php
include('class.palprimechecker.php');    //include the class Palprimechecker to be used next.
$checker = new PalprimeChecker();    // Create a new instance of Palrpime and store it in a $checker variable.
$checker->number = 17;                      // set the property number of $checker to 17.




echo "The number ".$checker->number;           //Here I access the value directly using the arrow notation.
echo "(is|is not)";
echo " a palprime.";

?>
