I'm afraid it just isn't possible to referecne a constant within a
string (or HEREDOC) without breaking out of the string first. The only
solution is to assign the value from the constant to a normal variable
before the HEREDOC block:

$constant = _CONSTANT;

print <<<EOD
<h1>Hi there, $constant</h1>
EOD;

Cheers,

Simon
