is it possible to display constants php's EOT? for example:
<?
define('Hey', "HellO");
echo
<<<EOT
Hey
EOT;
?>

A:
Nope. Just like you can't display a constant inside of a string. There are only two real ways to access a constant's value:
Directly in code:
$foo = Hey;
Or using the constant function:
$foo = constant('Hey');

The hrids way would be to do a concatenation liek 'Echo static: ' . Hey . ' is fun';

@iTroubs: Assuming you mean "third way", no it isn't, that is "Directly in code", so it is the first way again.

@iTroubs: to PHP's parser, it's identical to putting it directly in code (the same parser tokens are generated)...

You are right. I see my error ;-)

A:
No, the heredoc syntax (<<<) acts just like a double quoted string in PHP. It will expand variables, but not constants.
You can see a comment in the PHP documentation indicating this here. There is also an editors note on the comment saying that it is correct.
