PHP Tutorial Making.

I want to make some basic tutorials and use color using the highlight_string(); command.... but when I do that I get my variables turned into blanks. How can I show the code properly?

Also why is it when I do it that way...I get this 1 right after that command when I run it in my browser.

Hi,
If you want to achieve something like this:
http://www.innovative-webdesign.co.uk/lukus/phpstuff/highlight3.php

This is the code:
-----
<?php

echo "welcome, this is the script ur gonna use:";
echo "<hr>";

$string = '
<?php
if($myName == 'Lukus')
$myEmail = 'blahblahblaha';
elseif($myName == 'Dave')
$myEmail = 'b;ahbahashdasd';

/*
Commentasasdasda asd asdasdasd
*/
?>
';

ob_start();
highlight_string($string);
$output = ob_get_contents();
ob_end_clean();

echo $output;
?>

AHHHH!!!!

THANK-YOU! I was using " when it shoulda been '!!

THANKS. I am extremely happy if you cant tell.
