public function int doThing(string $foo) { return 1; }
The above is the best (ie omit 'return' or 'returns').
This also is consistent with C and with the way that the manual is written, eg:
http://www.php.net/manual/en/function.strlen.php
The only argument is the relative ordering of the keywords.
We keep 'function' - since that is the way that the language works.
Things like 'public' we put before 'function' since that is the way that
it works in PHP 5 objects.
So the only thing to decide is where the type goes:
public function int doThing(string $foo) { return 1; }
or:
public int function doThing(string $foo) { return 1; }
I would favour the first one, this is probably also easier to parse, as
following 'function' and before '(' you can have:
* 1 word - which must be the name of the function
* 2 words - the first word is the return type, the second the function name.
If the function returns a reference to something of a particular type, where
does the '&' go:
public function &int doThing(string $foo) { return 1; }
or:
public function int& doThing(string $foo) { return 1; }
I would suggest the second, ie just before the function name.
