Iphone/web サイト アプリ (instamapper) から GPS 座標を取得し、それを自分の web サイト ページに追加する php/javascript コードがあります。（これまでのところ、他の人々のコード例のスニペットを使用しています）ポップアップを小数点座標の表示から適切な緯度/経度に変更したいのですが、うまくいきません。皆さんが与えることができる助けや指針は素晴らしいでしょう。私のコードは以下です。

ここにあります http://www.morvargh-sailing.co.uk/tracker/test2.php 

<?php

$key = "16194603621692259587";

$fichier = "http://www.instamapper.com/api?action=getPositions&key=".$key."&num=1";
$fp=@fopen($fichier,"r");
$texte = "";


if($fp)
{
while(!feof($fp))
{
$texte .= fgets($fp,1024);
}

}
$donnees = explode(',',$texte);

/*

2. Position timestamp in UTC (number of seconds since January 1, 1970)

7. Heading in degrees

date_default_timezone_set('GMT');
$name = $donnees[1];
$date = date('H:i:s d-m-Y e', $donnees[2]);
$lat = $donnees[3];
$longitude = $donnees[4];
$altitude = $donnees[5];
$speed = $donnees[6];
$heading = $donnees[7];

この機能を試してください: http://jsfiddle.net/eAUJr/1/

function format(newLat, newLng) {
    if (newLat < 0) {
      newLat = myround(Math.abs(newLat)) + "S";
    } else {
      newLat = myround(newLat) + "N";
    }

    if (newLng < 0) {
      newLng = myround(Math.abs(newLng)) + "W";
    } else {
      newLng = myround(newLng) + "E";
    }

    return[newLat, newLng];
  }



  function myround(val) {
    deg = parseInt(val);
    val -= deg;
    val *= 60;
    min = parseInt(val);
    val -= min;
    val *= 60;
    sec = parseInt(val);
    remainder = val - sec;
    if(remainder >= 0.5) {
      sec += 1;
    }

    return deg + "°" + min + "'" + sec + '"';

  }

document.write(format(-0.000277778, 20.292))
// output: 0°0'1"S,20°17'31"E
