heredoc simply not displaying output

[spufi]

<?php
print <<<END
Hello World.
END;
?>

As basic as it comes and I can't get any output.

I'm using PHP 4 point something on Apache 2. I've had no problems with Apache 2 yet, and I don't see why it would be the server. Regular print and echo works fine.

isn't that cgi method???

your exact code works fine and dandy here. browser cache, perhaps?

I have print statements that work before the heredoc statement and after I add the heredoc statement, I get no output. I remove the heredoc statement and I get the output from the print statements that were already included so I don't think it's a browser cache issue.
