For an upcoming project a SOAP webservice has to be developed in PHP. The choice of language/environment has already been made, cannot be affected by me.
This must become an enterprise-grade application supporting business critical processes.
I will need a framework for structure, database abstraction etc. I know Zend Framework is used for these type of apps, but I don't have experience with it. I also not sure about the learning curve.
I have some experience with Yii framework and I like it. Also, I know it has some support for SOAP including WSDL generation.
Does anyone have experience with big apps build with Yii and more specific Yii and SOAP? Are there any other know solutions I don't mention here?
Edit: the webservice must comply with WS-Security as well; does ZF provide means to do this?
I'd recommend Symfony2. It's a new, highly scalable framework that's somewhat based on RoR/Spring.
I could describe it's features for hours, so I'll just give you the link to the website: http://symfony.com/
http://symfony.com/doc/2.0/cookbook/web_services/php_soap_extension.html
Also, it's very easy to incorporate 3rd party libraries to the symfony2 - probably Zend_Soap would interest you.
Cheers
I want to advise you to use Zend Framework. Especially Zend_Soap. It is very easy to use. It has WSDL autogeneration, adapters to the DB and etc. Tutorial
