although the Json is more widely acceptable serialization/deserialization scheme than WDDX, but the decoding speed with Chinese character in WDDX in PHP is much faster than Json; the same several MB serialized data file can deserialize in only ~80ms and for Json is 800ms, 10 times difference !!!

Two pure-php implementations of the json protocol that might be of use, e.g. for php 4 installs where adding extensions is not an option or because of extra functionality can be found here:
http://sourceforge.net/projects/phpxmlrpc (look for the extras package)
http://mike.teczno.com/json.html
Of course, performance is abysmal compared to the php extension, written in highly optimized C code...
