I think there isn't a problem with "echo" as it will call the string handler. However, in other cases it might be problematic.
Maybe a solution is to implement an equals function so that people would do:
if ($doc->name->equals("Hello")) ?
I don't think we can support auto-string conversion transparently everywhere in the engine. print and echo are special cases and we also supported make_printable_zval() in PHP 4.
Well, the comparison operator should be overloaded if one of the objects is an overloaded object imho.
The problem is that user-land overloading can't be supported. C extensions might be able to be supported but I don't think it's a good idea to start hacking this into PHP. It wouldn't end at the comparison operator but people would want it to work everywhere.
I don't want user overloading - I've been consistently against that for objects of all types. I want it internally cause its important to be able to overload all operations for something like SimpleXML to properly work. The same applies to ext/mono (has the same issues as java, but even more due to field and property distinctions.)
My concern lies more with functions like utf8_encode() not properly getting the contents of the XML string - but I haven't looked into it too much - I'll try and get some hacking done on the cruise.
The way to do it today is to do a cast to (string) although I admit it's not a beautiful solution.
Right - what I don't understand is that why doesn't convert_to_string_ex() handle this?
