in php4 you need to put var before the variable, in php5 you can control the scope of the variable with public, protected or private. Or var for php4 compatibility.

Drop Global Variables for CI. COmpletly.
If you want a way to permiate variables throughout CI make a library that autoloads variables to a class variable. Then you access it like this:
Code:
$this->LIBRARY_NAME->config['VARIABLE_NAME'];Cant I declare global varirable in controller? - El Forum - 06-19-2008

Oh and to access class functions and variables in-class you need a $this-> in front of what you are trying to access. EG
Code:
class Testlibc extends Controller
{
$sql_q="SELECT * from del_user"; //it gives error here
function index()
{
echo $this->sql_q;
}
}
