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!
