使用PHP / javascript构建和发送SOAP消息的最佳实践

Question

I need to construct SOAP message from database query search results and send it to another server. Can you give me a quick guide of how should I do it? I was told I should json encode query results in PHP, pass json to javascript and create SOAP xml using RESTful in javascript. Any ideas what would be the best way to do this task?

Thanks ^.^
