Question

我正在从另一台服务器获取json数据，并且需要将thouse数据保存在mysql中。我尝试了这段代码，但是存在问题当我运行此代码时，我得到：每个值的字符串偏移量非法。我希望我能说清楚什么，如果我没有解释，请告诉我。

    <?php
       require('db.php');
      $url = 'xxxxx';
        $data =json_encode(array('xxx' => 'xxxx',
            'xxxx' => 'xxxxx',
            'xxxx' =>'xxxx',
            'xxxx' =>'xxxx',
               'xxxx' =>'xxxx')
   );


   $options = array(
   'http' => array(
    'header'  => "Content-type: application/json",
    'method'  => 'POST',
    'content' => $data
  )  
   );
    $context= stream_context_create($options);
   $result = file_get_contents($url, false, $context);
  if ($result === FALSE) { }

   echo $result ;

  foreach ((array)$result as $row) {
   $table="INSERT INTO table_name(xxx,xxx,xx,xxx,xx,xxx,xxx,xxxx,xxx) 
    VALUES('".$row["xxxx"]."','".$row["xxx"]."','".$row["xxx"]."','".$row["xxx"]."','".$row["xxx"]."','".$row["xxx"]."','".$row["xxx"]."','".$row["xxx"]."','".$row["xxxx"]."')";
   if ($conn->query($table ) === TRUE) {
  echo "Record added Successfully<br>";
   }
   else
  {
   echo "Error: " . $insert_value . "<br>" . $con->error;
 }
 }

  ?>

在有else条件的情况下，也应该有if语句，以防有结果。结果应该在else中解析。

代码应为：

$context = stream_context_create($options);
$result = file_get_contents($url, false, $context);
if ($result === FALSE) {
    echo "Error in fetching records.";
} else {
    echo $result;
    $rows = (array) $result;
    foreach ($rows as $row) {
        $table = "INSERT INTO table_name(xxx,xxx,xx,xxx,xx,xxx,xxx,xxxx,xxx) 
    VALUES('" . $row["xxxx"] . "','" . $row["xxx"] . "','" . $row["xxx"] . "','" . $row["xxx"] . "','" . $row["xxx"] . "','" . $row["xxx"] . "','" . $row["xxx"] . "','" . $row["xxx"] . "','" . $row["xxxx"] . "')";
        if ($conn->query($table) === TRUE) {
            echo "Record added Successfully<br>";
        } else {
            echo "Error: " . $insert_value . "<br>" . $con->error;
        }
    }
}

使用PHP将JSON数据保存到MySQL中
