or rather than md5 fields, make it more multidimentional and check with 
isset,

Array1=array(
     "Offset"=>array(
         "Business Cards"=>array(
             "Customer"=>1,
             "InHouse"=>1
         ),
         "Flyers"=>array(
             "Retailer"=>1
         )
     )
)

if($Array1["Offset"]["Business Cards"]["Customer"]) or 
if(isset($Array1["Offset"]["Business Cards"]["Customer"])) will give you 
what you want
