You're right, but I don't consider this to be really special behavior of
echo/print.  Actually that behavior is the same for all (built-in)
functions and operators expecting (a) string(s).

Thanks for correcting the typo. :)

Actually, I was aware of that, but I've chosen to ignore it, because PHP
tutorials should mention that (at least as a side note).  Unfortunately,
many don't, and in my experience a lot of PHP programmers are not aware
of the CLI SAPI, so it's probably a good idea to point that out.
<http://php.net/manual/en/features.commandline.php> appears to be a good
starting point for those not yet accustomed using the command line
interface, which can save a lot of time (for instance, wrt. to quick
experiments).
