Zend framework with CI

[eluser]Yousra[/eluser]
Thanks for your help....I fixed the error.. I am try to build a web services security(Soap) and I found out that Zend framework have classes to implement Soap...but I already began with CI so I didn't want to change it...the problem with Zend that it's so difficult to understand because it needs to configure and create your index.php(which it called bootstrap) CI is very easy to use and simple comparing to zend framework.However zend framework is more security than CI in many ways....
