Hello.

That's what I do for a medium project I work on, and it works nicely.
The whole interface is in GWT, and server only sends JSON, with a few
exceptions.
One important point to take care of, with JSON coming from PHP, is the
values's type, not intuitive when working with PHP which converts implicitely.
If you have a class MyClass extending JavaScriptObject, that you get through a
simple conversion of the received JSON using eg
public static native T fromJson(String json, Class
name) /*-{
return eval(json);
}-*/;
and this class uses native properties like:
public final native int getId() /*-{ return this.id; }-*/;
then you must ensure the PHP code correctly converts data to int before
calling json_encode.
If you do eg
$json['id'] = $database_row['id'];
then PHP will write a string for the property, and some browsers (Chrome in
particuler) will complain and report an exception.
You have to explicitely use
$json['id'] = intval($database_row['id'];
This also applies to boolean types, for which you need to use PHP's
true/false, and not 0/1 or any other thing.
Apart that, you should be ok :)

Should be possible, as you can generate and read XML with GWT, and unless I'm
mistaking that's what SOAP uses. Not sure if there are wrappers to simplify
reading/writing, though.
Hope this helps
