跟踪设备的数据发送在$GPRMC这不是我在我的代码中使用的将是谷歌的PHP转换为十进制格式的方法没有用。
刚刚得到的解决方案，这不得不煮沸我的头上的内容$GPRMC样本格式eidog$GPRMC,001225,A,2832.1834,N,08101.0536,W,12,25,251211,1.2,E,A*03
其中：

*6A          The checksum data, always begins with *

和代码：

$gps = $_REQUEST['gps'];

if($gps){
$buffer = $gps;
if(substr($buffer, 0, 5)=='GPRMC'){

    $gprmc = explode(',',$buffer);
    $data1['lattitude_decimal'] = DMStoDEC($gprmc[3],'lattitude');
    $data2['longitude_decimal'] = DMStoDEC($gprmc[5],'longitude');

    $data = 'http://maps.google.com/maps?q='.$data1['lattitude_decimal'].','.$data2['longitude_decimal'].'+(PHP Decoded)&iwloc=A';

    print_r($data);
    echo "\n\n";
}
 }
   function DMStoDEC($dms, $longlat){

if($longlat == 'lattitude'){
    $deg = substr($dms, 0, 2);
    $min = substr($dms, 2, 8);
    $sec = '';
}
if($longlat == 'longitude'){
    $deg = substr($dms, 0, 3);
    $min = substr($dms, 3, 8);
    $sec='';
}

return $deg+((($min*60)+($sec))/3600);
  } 

  ?>

希望这能帮助到一些人
