反向地理编码不能给出正确的位置

我有一个编码的XML文件，其中包含多个ride。我想使用反向地理编码来检索实际位置。但是当我上传XML文件时，刷新页面时会得到不同的位置。它似乎是缓存，因为有很多位置，与上面的位置相同。

//Get Location Start
    //Get location
$url = "http://maps.googleapis.com/maps/api/geocode/json?latlng=".$locBegLat.",".$locBegLon."&sensor=false";
$data = @file_get_contents($url);
$jsondata = json_decode($data,true);
if(is_array($jsondata) && $jsondata['status'] == "OK"){
//street
        foreach ($jsondata["results"] as $result) {
foreach ($result["address_components"] as $address) {
    if (in_array("route", $address["types"])) {
        $streetBeg = $address["long_name"];
    }
}
}
//street_number
               foreach ($jsondata["results"] as $result) {
    foreach ($result["address_components"] as $address) {
        if (in_array("street_number", $address["types"])) {
            $street_numberBeg = $address["long_name"];
        }
    }
   }
// city
foreach ($jsondata["results"] as $result) {
    foreach ($result["address_components"] as $address) {
        if (in_array("locality", $address["types"])) {
            $cityBeg = $address["long_name"];
    }
    }
    }
// postal_code
foreach ($jsondata["results"] as $result) {
    foreach ($result["address_components"] as $address) {
        if (in_array("postal_code", $address["types"])) {
            $postal_codeBeg = $address["long_name"];
    }
}
}
// country
foreach ($jsondata["results"] as $result) {
foreach ($result["address_components"] as $address) {
    if (in_array("country", $address["types"])) {
        $countryBeg = $address["long_name"];
    }
}
}
}
    $LocBeg = $streetBeg . " " . $street_numberBeg; 
echo $streetBeg;    
echo $street_numberBeg;
echo $cityBeg;  
echo $countryBeg;
echo $postal_codeBeg;

我希望有人知道，为什么使用相同坐标的位置不同，只需在上传文件后刷新页面即可。
