Tedd,
Actually, he seems to be needing the return value of the function inside the
if block. So, he would need to do:
if ($result = do_something('hello'))
or, as Adam stated:
if ( ($result = do_something('hello')) !== false )
Regards.

Chris:
You can shorten it even further by:
if(do_something('hello'))
{
// do something with $result
}
else
{
// do some other stuff
}
I don't think it's any different than calling any other function that
returns <whatever> or false.
I tried it out at --

-- with both pass and fail. All worked the same in all three ways.
