RE: [PHP-DEV] FW: Functionality request/proposal
Ok, let me try again.
Yeah, I know the C++ standard don't allow that semi-colon there... but both GCC
and CLang won't complain if you add it there, and GCC accepts it even in Java.
I've seem lots of code where people put it there, and I always get a little
frustrated when using PHP because I'm used on adding it (without even
noticing), and my code keeps failing because of that.
Wouldn't hurt to make the parser simply ignore it. =P
Know, about the multiple returns...
Ruby and Lua let you return multiple values... why won't PHP allow you?
Usually it's best to return an array, I totally agree, but I was working on a
Lisp-like parser for PHP yesterday and it would really help me for two
expressions to be returned from a single function, since I'm using tail
recursion and on a few cases I needed to add two values to an array.
You guys will tell me to use something like flatten(), probably
RecursiveArrayIterator or stuff, but... for future implementations, that
multiple return would help. =P
Better?

That one is wrong in C++, too. Unless you're confusing function
declarition with function definitions.
class CPPClass {
void some_declaration();
void some_definition_of_an_inline_function() {
return;
} // No ; here
}

Use
return [10, 20];
which exists and returns an array. This is clear and quite easy to read.

This becomes confusing when reading.
echo array_sum(multi()); // :)

You should propose it here and then create a rfc about it in the php
wiki, which is finally voted.

I don't think this is a good addition.

Are you aware that you could use arrays here?
function multi() {
return array(10, 20);
}
list($x, $y) = multi();
echo $y; // echoes 20
For passing to a new function it is a bit uglier but still easy:
echo call_user_func_array('sum', multi()); // echoes 30
Functions could be changed to receive the members of an array as the
different arguments, but that would conflict with passing an array as
the first argument. It would be also harder to read the code, too.

Hi!
> function multi() {

This can be done with:
function multi() {
return [10, 20];
}
list($x, $y) = multi();
However, sum() won't work this way:
> echo sum(multi()); // echoes 30
But can work this way:
call_user_func_array("sum", multi());
