Well, using "0" or 0 instead of "\0" would result in unintended
behavior.  Consider strpos() returning 0, because the $needle is found
at the very beginning of $haystack.  See <>, where
the second and third results are not desired.

However, I prefer the following way to test that a string is contained
in another string:

  if (strpos($haystack, $needle) !== false)
