Question

im开发一个vb.net应用程序并尝试做一个Web服务来连接到我的服务器并检索Mysql数据，它是一个共享主机，因此当我的IP更改时，它不允许我远程连接，所以为什么我尝试这样做方法

这是我的代码

    <?php

if(isset($_GET['username']) && isset($_GET['password']))
{

    $connection = new mysqli($DB_IP, $DB_USER, $DB_PASSWORD, $DB_NAME);
    if ($connection->connect_error)
    {
    die('Connect Error (' . $connection->connect_errno . ') '
            . $connection->connect_error);
    }

    $username = $_GET['username'];

    $query =  $connection->query("Select u.*, p.* from users u, permisions p where u.IdUser = p.IdUser and username = '$username'");

    $result = $query->fetch_array();
     if($result)
     {
         $data['IsUser'] = 1;
         $data['IsPassword'] = 1;
         $data['Name'] = $result['NAME'];     
         $data['ApePat'] = $result['APEPAT']; 
                 $data['ApeMat'] = $result['APEMAT'];
                 $data['Repo'] = $result['REPO'];
                 $data['Coti'] = $result['COTIO'];
                 $data['isAdmin'] = $result['ISADMIN'];
                 $data['UserType'] = $result['USERTYPE'];
                 $data['Expires'] = $result['EXPIRES'];
                 $data['Perm1'] = $result['PREM1'];
                 $data['Perm2'] = $result['PREM2'];
                 $data['Perm3'] = $result['PREM3'];
                 $data['Perm4'] = $result['PREM4'];
                 $data['Perm5'] = $result['PREM5'];
                 $data['Perm6'] = $result['PREM6'];
                 $data['Perm7'] = $result['PREM7'];
                 $data['Perm8'] = $result['PREM8'];
                 $data['Perm9'] = $result['PREM9'];
                 $data['Perm10'] = $result['PREM10'];
                 $data['Perm11'] = $result['PREM11'];
                 $data['Perm12'] = $result['PREM12'];

     }
     else
     {
         $data['IsUser'] = 0;
         $data['IsPassword'] = 0;
     }

     echo json_encode($data);
}
else
{
    echo 'Required parameter not provied';
}
?>

当我发送参数时发生错误，它在此行上给我错误500

$result = $query->fetch_array();

PHP致命错误：在布尔值上调用成员函数fetch_array（）

这是即时通讯从vb.net发送值的方式

strReq = "http://gulsrv.com/dongle/getData.php?username=" & Uusername.ToString & "&&password=" & Ppassword.ToString
    request = WebRequest.Create(strReq)
    response = request.GetResponse()
    dataStream = response.GetResponseStream()
    reader = New StreamReader(dataStream)
    strData = reader.ReadToEnd()
    reader.Close()
    response.Close()

知道为什么吗？如果我仅测试php文件，可以说需要提供参数

将参数发送到php函数时出现错误500
