Different Data for Different users

i have created a dashboard to which all my users are being redirected开发者_开发知识库 to after login. Now, how do i display different data for different people?

Say for example, I want to display an additional object which would be a rounded rectangle for user John. I don't want the rounded rectangle to appear for user Chris.

How do i do that? Can you give me a brief overview with any links if possible.

Thank you.

I think you're looking for ACL management.

There are a lot of php script for that.

I use Zend_Acl.
