如何請求Google Place API返回地點的ID？

Question

我有一個PHP變量

$location = 'London'; 

我也有谷歌地圖API第3版的JavaScript來顯示我的地圖，並放置在一個地方ID標記

var request = { 
    placeId: 'ChIJN1t_tDeuEmsRUsoyG83frY4' 
}; 

我的目標是讓我的腳本請求把我的ID PHP變量和打印ID爲我的標記位置，就像這樣：

var request = { 
    placeID: '<?=$_locationID;?>' 
}; 

如何傳遞$ locati的地方ID作爲$ _locationID的值？

Answer 1

$data = "https://maps.googleapis.com/maps/api/place/textsearch/xml?query=".$location."&key=YOUR_KEY_HERE"; 

$xml = file_get_contents($data); 
$xml = simplexml_load_string($xml); 

foreach($xml->result->place_id as $key => $value){ 
    $location_id = $value; 
} 

有了這個代碼，我已經回到了正確的ID爲每個位置，在這種情況下我的$ location =「倫敦」

隨着地圖的JavaScript最後的結果是

Answer 2

您可以通過使用文本搜索做到這一點： -

當你搜索「倫敦」

function geoPlaceID($location){ 
    $locationclean = str_replace (" ", "+", $location); 
    $details_url = "https://maps.googleapis.com/maps/api/place/textsearch/json?query=" . $locationclean . "&key=YOUR_API_KEY"; 
    $du = file_get_contents($details_url); 
    $getDetails = json_decode(utf8_encode($du),true); 
    if ($getDetails['status']=="OK"){ 
     return $getDetails['results'][0]['place_id']; 
    } 
    else{ 
     return "Place ID not found"; 
    } 
} 

查詢結果中包含1分以上的結果：

因此，如果您搜索的名字最好是正確的地方，如果你使用的是谷歌地圖用於該地方的名稱，那麼只會有一個結果。例如：當您搜索「倫敦，英國」它會給結果只有一個：

{ 
    "html_attributions" : [], 
    "results" : [ 
     { 
     "formatted_address" : "London, UK", 
     "geometry" : { 
      "location" : { 
       "lat" : 51.5073509, 
       "lng" : -0.1277583 
      }, 
      "viewport" : { 
       "northeast" : { 
        "lat" : 51.6723432, 
        "lng" : 0.148271 
       }, 
       "southwest" : { 
        "lat" : 51.38494009999999,
