[PHP] RTFM code snippet

[mike cullerton]

hey folks, hope the new year is treating everyone well.

i was RTFMing yesterday and ran across this piece of code

  while (false !== ($file = readdir($handle))) {

which is similar to stuff i've done

  while ($file = readdir($dir)) {

so, what am i not catching with my code, and what is really going on in the
RTFM code with the "false !==" part?

thanks y'all,
mike
