Question about ?> bug or feature.

Hi all,

Could someone let me know if omission of the closing php tag from a
source file without generating an error is a bug or a feature? I've
always thought it a feature, but someone suggested on the general list
that it's a bug.

Thanks in advance,
Rob.

It's really neither.  It's a function of the language definition.
'<?php' means "start interpretting the following as PHP code".  '?>'
ends the PHP interpretation.  If there's no need to end the PHP
interpretation at the end of a file and return to "normal" output
mode, then the trailing '?>' is extraneous.

It's actually quite beneficial to leave it off in included files.
Trailing carriage returns will not mess things up for any headers that
might be sent after the include if you leave off the closing ?>

That's what I thought. Thanks guys, that's a fantastic feature :)

Cheers,
