I'm just starting PHP programming as you can tell. I want the results of each statement to be on their own line but can't get it to work yet. I tried referring to the code on this page and am obvsiously doing something wrong. Thank you very much.

<?
$mySentence="This is a sentence 123456789.";
$myNumber1 = 9.5;
$myNumber2 = .5;
$sum = $myNumber1 + $myNumber2;

echo "Hello, lets display our PHP variables: \r";
echo $mySentence;
echo "The sum of $myNumber 1 and $myNumber2 = $sum ";
echo "\"This text has double quotes\"";

?>
