代码点火器中是否有类似$ _REQUEST的预定义变量？

The variables in $_REQUEST are provided to the script via the GET, POST, and COOKIE input mechanisms.

Is there a way in code igniter to access GET and POST both data through one predefined variable or function

You can use

$this->input->post_get('some_data', TRUE);

This will work like $_REQUEST.More function are there like cookie,server.
