Specifically, it is possible to execute to the end of the function, but then what is the value of that invocation? Reproduce code: --------------- --- From manual page: language.functions --- Not in "returning values" or "return()" either. "Returning values" is probably the best place for it. Expected result: ---------------- Since many other languages will use the value of the last expression evaluated as the return value of a function which does not explicitly 'return', it would be helpful to note prominently that PHP (apparently) does not do this. It seems that the value of an invocation of such a function is NULL. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=50208&edit=1
