<?php
function test() {
	print("1");
	flush();
}
print("0".test());
?>

RESULT: 10

I think thats wrong!

Well, I would say it's counter-intuitive perhaps, but not wrong. :)

Think of it like a math expression, with parenthesis defining precedence:

             evaluated first
                  vvvv

    print( "0" . test() );

         ^              ^
         evaluated second

So the test() gets evaluated first which does it's flush(), then the rest.

(Besides, test() doesn't return anything, so printing it's result is probably wrong anyway.)

what you want to do is
return("1") instead of print("1")
in test()
