If you have a limited amount of variables, you could look into the
(s)printf() function.
printf('To:%1$s<br><br>%2$s<br><br>From:%3$s', $to, $message, $from);
Else, you could consider a kind of syntax of your own, like
'{{{var_name}}}'.
$to = 'Me';
$from = 'You';
$message = 'message in this case';
$string = 'To:{{{to}}}<br><br>{{{message}}}<br><br>From:{{{from}}}';
echo preg_replace('/{{{([a-zA-Z0-9_\-]*)}}}/e','$$1',$string);
I don't really like the e-modifier in this case, maybe others have a better
solution for this. Don't come knocking with eval(), that's even worse :P
