Question

我正在尝试更新mysqli数据库中的字段。我正在尝试使用googlemaps api将lat / lng地理编码填入数据库。我知道googlemaps有一个使用限制，但我在Google开发者控制台中创建了一个项目，并制作了一个API密钥。但我没有做的工作 - 我仍然得到OVER_QUERY_LIMIT错误。（我想，在试图解决我的代码时，我超过了极限。）

这是一个失败的原因吗？我是否必须手动查找每个地址的纬度/经度？如何获取每个（400多个）地址的googlemap lat / lng？

这是我的php代码：

include_once ('constants_test.php'); 
   // connect to database
    $mysqli = new mysqli(DB_HOST, DB_USER, DB_PASSWORD, DB_NAME); 
    if (mysqli_connect_errno()) {
            printf("Connect failed: %s", mysqli_connect_error());
            exit();
    }

    date_default_timezone_set('America/New_York');
    $q = "SELECT provider_ID, location FROM `data` where point = ''";
    $result = $mysqli->query($q);

    while($row = $result->fetch_array(MYSQLI_ASSOC)) {
         $location = $row['location'];
         $provider = $row['provider_ID'];
         set_time_limit ( 120 );
         geocode($location, $provider);
    }

    function geocode($address, $provider){

    // url encode the address
    $address = urlencode($address);

    // google map geocode api url
    $url = "http://maps.google.com/maps/api/geocode/json?address={$address}&sensor=false";

    // get the json response
    $resp_json = file_get_contents($url);

    // decode the json
    $resp = json_decode($resp_json, true);
    echo $resp['status'];
    // response status will be 'OK', if able to geocode given address 
    if($resp['status']=='OK'){

        // get the important data
        $lati = $resp['results'][0]['geometry']['location']['lat'];
        $longi = $resp['results'][0]['geometry']['location']['lng'];
        $formatted_address = $resp['results'][0]['formatted_address'];

        // verify if data is complete
        if($lati && $longi && $formatted_address){
            $new_location = "(" . $lati . "," . $longi . ")";
            $mysqli2 = new mysqli(DB_HOST, DB_USER, DB_PASSWORD, DB_NAME); //open db conn
            $new_q = "Update `data` set point = '" . $new_location . "' where provider_ID = '" . $provider . "'";
            echo $new_q;    

            $result2 = $mysqli2->query($new_q);

        }else{
            return false;
        }

    }else{
        return false;
    }
}

使用googlemaps api使用php和mysqli对地址进行地理编码
