Try like this: it may work..

If u use any outer variable in a function, then decleare as global $use_variable_name . now u can understand...

function get_data(){
global $obj;
$obj->test();

}

another and better way:

get_data($obj);// call this way...
function get_data($object){
$object->test();

}

Why should the OP "try this"? Please add an explanation of what you did and why you did it that way not only for the OP but for future visitors to SO. – Rizier123 May 10 '15 at 17:16
I have doubt in this concept how to access object inside function.... In codeigniter i did $ci =& get_instance() to access object so that – user3743689 May 10 '15 at 17:22

@Rizier123 Yes i know – user3743689 May 10 '15 at 17:37
@user3743689 To use `global` is **very** bad practice! Pass the variable as argument to the function – Rizier123 May 10 '15 at 17:39
