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.)
```palprimes.php
<?php include('class.palprimechecker.php');
$checker = new PalprimeChecker();
$number->17;
echo "The number" . $number;
echo "(is|is not)";
echo " a palprime.";
?>
```

hey @Raul Chiru (https://teamtreehouse.com/raulchiru) ,
I'll try to walk you through this, so let's do it together step by step:
part1: PalprimeChecker objects have a property called number. assign that property a value of 17.
we already created a new PalprimeChecker object and saved it as $checker. So now we can use this one to set the number on it, like this:
php
$checker->number = 17;

as you see we access the number property on our object and then tell it to hold the number 17. part 1 done ;)
part2:  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.)
so our end result should be text ("the number") + space + number (the one we created in part1) + space. we can do it like this:
php
echo "The number " . $checker->number . " ";

we first echo the text with a space after the word. then we use the number from part1 and at the end we add another space, all done using concatenation. that's it - the task will pass just fine.
hope that helped you out - have a nice day ;)
