    <?php
require 'database.php';
if ($_POST['address'])
{   
    $address = $_POST['address'];
    $string = str_replace (" ", "+", urlencode($address));
    $geocode=file_get_contents('https://maps.googleapis.com/maps/api/geocode/json?address='.$string.'&key=AIzaSyD5Dqe3SK3kKOZqKT5Rxk_JZskcoCf4J3g');

    $output=json_decode($geocode, true);
    $lat = $output['results'][0]['geometry']['location']['lat'];
    $lon = $output['results'][0]['geometry']['location']['lng'];
    echo "<pre>";
    print_r($output);
    echo "</pre>";

    $insta = file_get_contents('https://api.flickr.com/services/rest/?method=flickr.photos.search&api_key=eabad3d02e824ce76245158db270c855&lat='.$lat.'&lon='.$lon.'&per_page=20&format=json&nojsoncallback=1');
    $out = json_decode($insta);
    echo "<pre>";
    print_r($out);
    echo "</pre>";

        $sql = "INSERT INTO geo (latitude, longitude) VALUES ($lat, $lon)";

        if ($db->query($sql) !== False) {
            echo "New record created successfully";
        } 
        else {
                echo "Record Entry Failed";
            }


        $photos = $out->photos->photo;
        foreach($photos as $photo) {
            $id= $photo->id;
            $owner = $photo->owner;
            $secret = $photo->secret;
            $server = $photo->server;
            $farm = $photo->farm;
            $title= $photo->title;
            $sql = "INSERT INTO flickr (id, owner, secret, server, farm, title) VALUES ($id, $owner, $secret, $server, $farm, $title)";
            if ($db->query($sql) !== false) {
            echo "New record created successfully";
            } 
            else{
                echo "FAILED";
            }
            $url = 'http://farm'.$photo->farm.'.staticflickr.com'.'/'.$photo->server.'/'.$photo->id.'_'.$photo->secret.'_b'.'.jpg';
            echo '<img src="'.$url.'"/><br/>';
            echo "<pre>";
            print_r($id);
            echo "</pre>";



}   

    $conn->close();

【问题讨论】：

在一行中您引用$row['results']，但在下一行您引用$row->lat。那么它是一个对象还是一个数组？既然您说不插入纬度和经度，我假设它是一个数组。投票结束错字。
我尝试将其作为数组插入，但没有成功。我试过 $row[ ' ['results'] [0] ['geometry'] ['location'] ['lat'] ' ]

【解决方案1】：

试试这个代码。我没有将“search_id”包含在查询中，因为您的地理表架构说它是自动递增的。

                                if ($_REQUEST['address'])
                            {   
                                $address = $_REQUEST['address'];
                                $string = str_replace (" ", "+", urlencode($address));
                                $geocode=file_get_contents('https://maps.googleapis.com/maps/api/geocode/json?address='.$string.'&key=AIzaSyD5Dqe3SK3kKOZqKT5Rxk_JZskcoCf4J3g');

                                $output=json_decode($geocode, true);
                                $lat = $output['results'][0]['geometry']['location']['lat'];
                                $lon = $output['results'][0]['geometry']['location']['lng'];

                                $insta = file_get_contents('https://api.flickr.com/services/rest/?method=flickr.photos.search&api_key=eabad3d02e824ce76245158db270c855&lat='.$lat.'&lon='.$lon.'&per_page=20&format=json&nojsoncallback=1');
                                $out = json_decode($insta);

                                $sql = "insert into geo (latitude,longitude) values(?,?)";
                                $stmt = $mysqli->prepare($sql);
                                $stmt->bind_param('ss',$lat,$long);

                                foreach($output['results'][0]['geometry']['bounds']  as $row) {
                                    $lat = $row['lat'];
                                    $long = $row['lng'];
                                    $stmt->execute();
                                }
                                $stmt->close();

                                $sql = "insert into flickr (photo_id, owner, secret, server, farm, title) values(?,?,?,?,?,?)";
                                $stmt = $mysqli->prepare($sql);

                                foreach($photos as $photo) {
                                    $id= $photo->id;
                                    $owner = $photo->owner;
                                    $secret = $photo->secret;
                                    $server = $photo->server;
                                    $farm = $photo->farm;
                                    $title= $photo->title;
                                    $rc = $stmt->execute();
                                    if ( false===$rc ) {
                                      die('execute() failed: ' . htmlspecialchars($stmt->error));
                                    }
                                    $tid = $stmt->insert_id;

                                    if ($tid) {

                                    }
                                }

你能帮我处理 flickr json 数据吗
我正在将它运行到我的本地机器 (localhost/stackoverflow/test.php?address=saket,new%20delhi) 并且它成功地将数据插入到地理表中。使用我的 URL 中的地址后检查 json 数据或分享您在发布请求中传递的地址。
我尝试在不使用 prepare 语句的情况下插入纬度和经度，这为我解决了问题，我已经更新了代码。但现在我遇到了 flickr json 文件的问题。由于某种原因，我无法将其插入到我的数据库中。你也可以帮我解决这个问题吗？
请检查我的 sql 语句以获取上述代码中的 flickr json。
您会在执行该查询时分享 mysql 错误吗？如果我错了，请纠正我，现在您在将数据插入“flickr”表时遇到问题？
