curl返回null值

Question

I am working on Geo coding some addresses and I found an example that uses cURL to extract the json data. For some reason it keeps returning null I have echoed the $url and copied it into the address field of my browser and it works as intended so I know the URL is valid. Does anyone spot a mistake in my code?

for($count=0; $count < count($uploadedArray); $count++) {
    $address = "";
    $address .= $uploadedArray[$count]["Address"] . " ";
    $address .= $uploadedArray[$count]["City"] . ", ";
    $address .= $uploadedArray[$count]["State"] . " ";
    $address .= $uploadedArray[$count]["Zip"];
    $url = urlencode("https://maps.googleapis.com/maps/api/geocode/json?address=" . $address . "=%s&sensor=false");
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    $geoloc = json_decode(curl_exec($ch), true);
    var_dump($geoloc);
    echo $geoloc['results'][0]['geometry']['location']['lat']; // get lat for json
    echo $geoloc['results'][0]['geometry']['location']['lng']; // get ing for json
}

You shouldn't use urlencode on the whole url. You should use it only on the parameters:

$url = "https://maps.googleapis.com/maps/api/geocode/json?address=" . urlencode($address) . "=%s&sensor=false";
