Looks like you have empty values for array index

try with isset() or empty() like

isset($privillage_data[0]) or !empty($privillage_data[0])

and so on... for all index

so your condition will be

if((!empty($privillage_data[0]) && $privillage_data[0] == '1') || (!empty($privillage_data[1]) && $privillage_data[1] == '1') || (!empty($privillage_data[2]) && $privillage_data[2] == '1') && $count >=1)

and so on for all conditions you are using

Dump out the contents of privillage_data. There's an array key missing that you're expecting. Also, which line above is giving the error?
