JSON 配列オブジェクトから値を取得することに成功していません。私は特にジオメトリ->場所->緯度に到達しようとしています
これが私がやっていることです:
$url='http://maps.googleapis.com/maps/api/geocode/json?address='.$a.'&sensor=false';
$result = file_get_contents($url);
$jsonArr = json_decode($result,true);
echo "Lat: ".$jsonArr['results']['geometry']['location']['lat'];
以下は、Google から返された JSON の print_r() です。
