Hello Cristiano,

Maybe the __tostring() will be the best because few naming
conventions for methods exist. Some people prefer C-like some_method(), some
like Java-like someMethod() etc. But there is already in PHP5
pre-defined methods like __clone, __construct, __destruct so the
"__tostring" name will be expected by user. The "__to_string" will
also be though. I have seen no "__" methods with names having two
words so this variants are equal from my point of view.

The printable is IMHO definetly not good name for such interface. When
user sees the "implements Printable" he expects methods like
print(), println() etc. that do something, not return strings.
I can't name this interface better though.
Maybe it will be better to have this method in all classes and define
default behavior such as existing ( string )$object cast?
