I have a sequence of number like follows

1 -> 25, 2 -> 60, 3 -> 80, 4 -> 100 and so on

which means that if input is 1 output will be 25 and so on...I need to store it in global array.I would like to use it in multiple pages also.In codeigniter where i can declare a global array and store all these?

I am trying like as follows in constants.php

$CONFIDENCEVALUE = array(); $CONFIDENCEVALUE[] = array('1'=>25,'2'=>'60','3'=>80,'4'=>100);

If it is correct how can access these array value in required pages.Help me please.I am not an expert with codeignitor.Thanks
