I'm trying to find a clever way of determining a list of unique string from the following array data: 

$VAR1 = 'Devices_CLI_Inspection';
$VAR2 = 'Devices_CLI_Inspection_L2';
$VAR3 = 'Devices_CLI_Inspection_L2_FilterDatabase_General';
$VAR4 = 'Devices_CLI_Inspection_L2_SpanningTree';
$VAR5 = 'Devices_CLI_Inspection_L2_SpanningTree_MST';
$VAR6 = 'Devices_CLI_Inspection_L2_VLAN_General';
$VAR7 = 'Devices_CLI_Inspection_System_Config';

[download]
I would expect the output to look like this: 
Devices_CLI_Inspection

  L2
    FilterDatabase_General
    SpanningTree
      MST

  L2
    VLAN_General

  System_Config

Any thoughts?
