Calling a Property

I never saw calling a property described, so I'm not exactly sure how to do it. Here is my code:

<?php include ('class.palprimechecker.php'); $checker = new PalprimeChecker(); $checker -> number = 17;


echo "The number "<?php number?> "; echo "(is|is not)"; echo " a palprime.";


Help GREATLY appreciated

Just as you have assigned 17 to $checker->number, to retrieve number, you do the same, i.e. $checker->number

To concatenate, you use "." (period/dot), e.g. "abc".$checker->number."def" will give you abc17def

Finally, echo is part of php, so you shouldn't close the php <?...?> block

Thank you, sir.
