Well... Definitly depends on what kind of function it is... However, instead
of echoing in a function, most ppl recommend echo do_it(), were do_it() is
function do_it()
{
return "Hi";
}There are many builtin functions without a return value, simply cause they don't need to, or there's no real logic in doing so... If you have a function named something like output_fmt($str), which is only meant to format a string and output it, there might not need a return value... Maybe the output itself, but you get the idea.. Some things just doesn't make sense to return... And some things might return to a parameter... Right now I can't think of an example though.. -- // DvDmanDT MSN: dvdmandt€hotmail.com Mail: dvdmandt€telia.com "Shawn McKenzie" <[EMAIL PROTECTED]> skrev i meddelandet news:[EMAIL PROTECTED] > Maybe a dumb question, but as good coding practice, should all functions > return something even if they don't need to??? > > Example: > > function do_it() > { > echo "hi"; > } > > --or-- > > function do_it() > { > return echo "hi"; > } > > Also, if they do other things but really don't return anything, should they > return true maybe??? > > Just curious! > -Shawn -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
