In the form of (116.414922,40.035715,0.0)(116.415122,40.035715,0.0)(116.415122,40.035515,0.0)(116.414922,40.035515,0.0)...This kind of data can be parsed using regular expressions
php中

$result = array();


preg_match_all("/\((\d{0,3}.\d{1,6})*\)/",$gps['gps'],$result);


foreach($result[0] as $row2){
    $res = 0;
    preg_match_all("/\d{1,3}.\d{1,6}/",$row2,$res);


    $gps_array = array();//gps_array中有3个数据分别是:经度、纬度和海拔
    foreach($res[0] as $row3){


        array_push($gps_array,$row3);
    }
}

js中
var gps_array = gps.match(/\((\d{0,3}.\d{1,6})*\)/g);


var sub1 = new Array();
for(var j = 0;j < gps_array.length;j++){
var gps_array1 = gps_array[j].match(/\d{1,3}.\d{1,6}/g);
var sub2 = new Array();
for(var k = 0;k < gps_array1.length;k++){
sub2.push(gps_array1[k]);
}
sub1.push(sub2);
}
