Why are you using HEREDOC to begin with? I personally find them to be ugly
and more trouble than they're worth.
You can write the same thing as this I think (untested):
$template = eval(file_get_contents($file));
But you might also consider using "include_once" or "require_once" instead
of this "eval()" business.
Also note, that a string can span more than one line and have variables in
it. It can even be used with code, so HEREDOC is again useless for most
situations:
$foo = "
Hello $name,\n
\n
Today is ".date('Y-m-d')."\n

Quisque elit mauris, varius sit amet cursus sed, eleifend a mauris.
