Uhm.... you don't need braces around arrays unless you're using more
than one dimension in the array.
This works perfectly fine for me:
<?php
$bar = array('hello' => "goodbye");
$foo = <<<EOT
$bar[hello]
EOT;
echo $foo; //echos out goodbye
?>
Something this simple should be common knowledge :X but I still agree
with Daniel that you ought to use {} around variables in HEREDOC (or
double-quotes) as it makes your code much more readable.
