リクエスト文字列にタイプミスがあります:adressの代わりにaddress. 正しいリクエスト文字列は次のとおりです。
$url = "http://maps.googleapis.com/maps/api/geocode/json?address=$adr&sensor=false";
また、リクエスト文字列に貼り付ける前に、パラメーターにPHP のurlencode()関数を使用することをお勧めします。$adr
以前にリストされた変更を含むコードをコピーして貼り付けました。つまり、次のとおりです。
$str = "Street 1 ZIP City";
$adr = urlencode($str);
$url = "http://maps.googleapis.com/maps/api/geocode/json?address=$adr&sensor=false";
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_HEADER, false);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_ENCODING, "");
$curlData = curl_exec($curl);
curl_close($curl);
$address = json_decode($curlData);
print_r($address);
この例のブラウザでの出力は次のとおりです。
