I have a script which is passed the following array of Users:
$tmpU[0][0] = Original Login Date
$tmpU[0][1] = Last Login Date
$tmpU[0][2] = User name
I have written routines to do the following:
1) cycle thru array and check for current user
-if found, update [0][1] Last Login Date to current
-if not found, compare Current Date with Last Login
if greater than 15 minutes than empty array
2) cycle thru array again and check for empty value
-put non-empty values in new array
thus removing empty array values
3) check to make sure Current user was found/updated
-if not, add to end of array
4) sort array by value [3] user Name
This works for me, however, it seems like overkill and
I think it can be optimized. Can anyone please review the
code and identify any easier approaches?
Please someone take a look
