Passing Params to a page in key-value pair in CodeIgniter

I am using CodeIgniter, and I am new to it. I came to know that I can pass parameters to another page like http://example.com/users/list/param1/param2/param3/.... and so on.

Now on the destination php script, I can get it as $this->uri->segment(2) , but I must know that which l开发者_运维知识库ocation it is in the uri. Say I am getting param2 , I must know that it is uri segment 4. This is a great pain for me. I previously worked with ZEND , where we send parameters like http://examples.com/controller/action/key/value/key/value , Now in this case I can always dynamic number of parameters and I don't need to know their location in the uri, but I just need to know the key.

Qestion : Is there a way where I can pass parameters using GET in key-value pairs in codeigniter, like the one ZEND do?

Take a look at the function $this->uri->uri_to_assoc(n) in the URI class. It will take in your url segments as an associative array. You could then check whether the keys are present in it or not.
