limit output to only php print/echo statements?

is there a way to make a php page only output content that is generated
from php statements, such as print, or echo? ie: if I have whitespace
(or other text) outside my <?php .... ?block i do not want that to be
returned.

of course i can do this by making sure my php file starts with <?php and
ends with ?and there is no leading or trailing whitespace. but if
whitespace does creep into my file then it would be neat if there was
some kind of directive or something that would make sure it doesn't get
output.

i ask this because the output from my script will be interpreted by
another program so i want the output to be specific space delimited
values with no leading/trailing whitespace.

of course i should probably just output my content in xml format and
make my interpreting program parse xml, which accommodates for
whitespace... but... that would be smart, which i am not.

thanks!

Hi,

Like you said, keeping the file trimmed is the easiest way. You could
also try using output buffering (ob_start), and trimming the result.

Not necessarily true. There's nothing to stop you writing a filter (in
PHP or other language) which processes a PHP script to return just the
PHP code, and then pass that through the interpreter - and with
mod_rewrite it could all be done transparently. But its not the way to
solve the OPs problem.

not mean that PHP has any control over what's outside the <?php and ?>
tags. It means you're using a language (it could be ANY language) to
modify the text.

Make sure there's no leading whitespace (which is pretty obvious) and
simply leave off the ?at the end.
