I think I figured it out.
array( '350','351','352','353', ),
'AK' => array( '995','996','997','998','999', ),
'AZ' => array( '850','851','852','853','854', ),
'WI' => array( '530','531','532', ),
'WY' => array( '820','821','822','823','824', ),
);
$zip = 35261;
$state =
$states = array(
'AL' => array( '350','351','352','353', ),

Here's a sample:
array( '350','351','352','353', ),
'AK' => array( '995','996','997','998','999', ),
'AZ' => array( '850','851','852','853','854', ),
