問題描述

在我的一個 php 應用程序中，我必須從地址中找出該地點的緯度和經度.

In one of my php applications I have to find out the latitude and longitude of the place from address.

我試過這個代碼:

$json = file_get_contents("http://maps.google.com/maps/api/geocode/json?address=$address&sensor=false&region=$region");
$json = json_decode($json);

$lat = $json->{'results'}[0]->{'geometry'}->{'location'}->{'lat'};
$long = $json->{'results'}[0]->{'geometry'}->{'location'}->{'lng'};

但它顯示以下錯誤:

警告:file_get_contents(http://maps.google.com/maps/api/geocode/json?address=technopark, Trivandrun, kerala,India&sensor=false&region=IND) [function.file-get-內容]:無法打開流:HTTP 請求失敗！第 4 行 D:Projectslon.php 中的 HTTP/1.0 400 Bad Request

Warning: file_get_contents(http://maps.google.com/maps/api/geocode/json?address=technopark, Trivandrun, kerala,India&sensor=false&region=IND) [function.file-get-contents]: failed to open stream: HTTP request failed! HTTP/1.0 400 Bad Request in D:Projectslon.php on line 4

請幫我解決這個問題.

推薦答案

使用 curl 而不是 file_get_contents:

$address = "India+Panchkula";
$url = "http://maps.google.com/maps/api/geocode/json?address=$address&sensor=false&region=India";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_PROXYPORT, 3128);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
$response = curl_exec($ch);
curl_close($ch);
$response_a = json_decode($response);
echo $lat = $response_a->results[0]->geometry->location->lat;
echo "<br />";
echo $long = $response_a->results[0]->geometry->location->lng;
