But remember that PHP uses 0-based arrays. You need to check the return
*type* of strstr to distinguish between 0 and false. false is shorthand
for '', a string. (I think.) I *know* that:

if (is_int(strstr("Re:", $string)){
  $string = 'Re:' . $string;
}

is what you want.

Hmmm. Would $string =. 'Re:'; turn into the above?... Or am I taking the
pre- and post-operators "logic" too far?...
