Extend from SoapClient Examples

Just a collection gist of some assorted example SOAPClients. Code must not be stable or useful under all circumstances, these are examples. Most of the code is outdated, so you won't need to use it any longer in production code. I've just collected and compiled this together out of interest, the information normally is scattered around.

If you need to a start with PHP's SOAPClient start with the PHP manual page of it and read through the comments as well. Double check with exisiting bug-reports if given as many things are fixed since a comment was left.

SoapClientTimeout - Allow timeout settings with SOAP Requests

Example SOAPClient that overrides SOAPClient::__doRequest() to use curl to make the HTTP request.

SoapClientAuth - Allow HTTPAuth Access to WSDL

Example SOAPClient that registers a new stream-wrapper based on curl to allow WSDL retrieval from password protected sources.

/**
* SoapClientTimeout Class
*
* Example class on how to extend PHP's SOAPClient with a curl based HTTP transport layer.
*/
/**
* Class SoapClientTimeout
*
* Drop-in replacement for PHP's SoapClient class supporting connect and response/transfer timeout
*
* Usage: Exactly as PHP's SoapClient class, with three new options available:
*
* timeout The response/transfer timeout in milliseconds; 0 == default SoapClient / CURL timeout
* connecttimeout The connection timeout; 0 == default SoapClient / CURL timeout
* sslverifypeer FALSE to stop SoapClient from verifying the peer's certificate (not recommended)
*
* Limitations:
*
* - Does not take php ini setting default_socket_timeout into account.
