SOAPx4
by Dietrich Ayala (C) 2001 dietrich@ganx4.com
This project began based on code from the 2 projects below,
and still contains some original code. The licenses of both must be respected.
XML-RPC for PHP
originally by Edd Dumbill (C) 1999-2000
SOAP for PHP
by Victor Zou (C) 2000-2001 <victor@gigaideas.com.cn>
*/
/* changelog:
2001-07-04
- abstract type system to support either 1999 or 2001 schema (arg, typing still needs much
solidification.)
- implemented proxy support, based on sample code from miles lott <milos@speakeasy.net>
- much general cleanup of code & cleaned out what was left of original xml-rpc/gigaideas code
- implemented a transport argument into send() that allows you to specify different transports
(assuming you have implemented the function, and added it to the conditional statement in send()
- abstracted the determination of charset in Content-type header
2001-07-5
- fixed more weird type/namespace issues
