google maps - PHP different result when converting CID to LAT -

i have scripts converting cid lat , lac long. in localhost in production server (using same script) give me different result.

result in localhost: cid = 55073 => lat = -6.254678 (true result)

result in production server cid = 55073 => lat = 4288.712618 (incorrect result)

here's script

if(isset($lac) && isset ($cid))      {          $data = "\x00\x0e" .         "\x00\x00\x00\x00\x00\x00\x00\x00" .         "\x00\x00" .         "\x00\x00" .         "\x00\x00" .
