Question

我正在用angular和php构建一个项目，我试图从phpmyadmin表中删除一行，我在php中有这个错误。有人可以查看我的代码吗？

  <?php
     header('Content-Type: text/html; charset=utf-8');
    $connect=mysqli_connect("localhost", "root", "", "hamatkin");

      include_once 'file.php';
    mysqli_query($connect,"SET character_set_client = utf8");
    mysqli_query($connect,"SET character_set_connection = utf8");
    mysqli_query($connect,"SET character_set_results = utf8");
    // Check connection
    if (mysqli_connect_errno()) {
      echo "Failed to connect to MySQL: " . mysqli_connect_error();
    }

    $data = json_decode(file_get_contents("php://input"));


     $id = $data->id;
    $del = "DELETE FROM file WHERE id=".$id;

       mysqli_query($connect, $del);

    $newURL = "/hamatkin/#/allPriceOffers";
    header('Location: '.$newURL);
    ?>

使用var_dump（$ data）后：

<pre class='xdebug-var-dump' dir='ltr'>
<small>C:\wamp64\www\hamatkin\api\customers-tab\delete-priceOffer.php:43:</small>
<b>object</b>(<i>stdClass</i>)[<i>2</i>]
  <i>public</i> 'id' <font color='#888a85'>=&gt;</font>

Answer 1

试试这个：

$id = intval($data->id->customer_id);

新编辑有帮助吗？

Answer 2

json_decode($data, true)

混合 json_decode （字符串$ json [，bool $ assoc = false [，int $ depth = 512 [，int $ options = 0]]]）

accs 当为TRUE时，返回的对象将转换为关联数组。

请参阅文档here。

类stdClass的对象无法转换为字符串
