推荐答案

您尝试访问的不是文件的url，而是使用CURL直接访问文件.

You are trying to access url not a file, Use CURL instead to access file direct.

替换

        <?php
           $latlong = $row[1].','.$row[2];
           $geocode=json_decode(file_get_contents('http://maps.googleapis.com/maps/api/geocode/json?latlng=19.0978,22.8972&sensor=false',true));            
        ?> 

收件人

<?php
    $url = "http://maps.googleapis.com/maps/api/geocode/json?latlng=$row[1],$row[2]&sensor=false";
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    $output = curl_exec($ch);
    curl_close($ch);
    $geocode = json_decode($output);
?>
