数据库未响应Azure Microsoft

我一直在Microsoft Azure中对该服务器/数据库进行编程。我创建了这个PHP来控制一切。主要目标是创建一个可以注册和登录的网站，为此我需要一个处理所有这些值的数据库和服务器。在我的代码hoewever中，数据库似乎没有存储任何东西，除了数据库和PHP文档之间的连接之外，一切都按照预期进行。所以我转向你们，听说你们会是最好的哈哈！仅供参考，第一个帖子，请注意：）

这是我的PHP文档。

<?php
if (isset($_POST['submits']))
{
if (empty($_POST['usernames']))
{
  $error = "Fill in all the boxes";   
}
    elseif (empty($_POST['passwords']))
    {
      $error = "Fill in all the boxes";     
    }
    elseif (empty($_POST['emails']))
    {
      $error = "Fill in all the boxes";     
    }
     elseif(strpos($_POST['emails'], "@") === false)
{
     $error = "Wrong syntax: example@.com";
}
else
{    
    $username=$_POST['usernames'];
    $password=$_POST['passwords'];
    $email=$_POST['emails'];  
    $connectionInfo = array("UID" => "MY_SERVER_EMAIL", "pwd" =>    "   MY_PASSWORD", "Database" => "MY_DATABASE", "LoginTimeout" => 30, "Encrypt" => 1);
    $serverName = "(MY_DATABASE";
    $conn = sqlsrv_connect($serverName, $connectionInfo);       
    $sql = "SELECT username, email FROM dbo.Login";
    $stmt = sqlsrv_query( $conn, $sql );
    if( $stmt === false) {
        die( print_r( sqlsrv_errors(), true) );
    }
    $usertrue=TRUE;
    if($usertrue===TRUE)
    {
         $error = "Account added";
      $hashedpassword = md5(md5(sha1(sha1(md5($password)))));
      $query = "INSERT INTO dbo.Login (username, password, email) VALUES    ('$username', '$hashedpassword', '$email' )";
         $result = sqlsrv_query($conn, $query );
         if($conn->connect_error)
         {
                die("Connection failed: " . $conn->connect_error);
         }
         echo "Connected succesfully";
    }
    sqlsrv_free_stmt( $stmt);  
sqlsrv_close($conn); // Closing Connection
}
}
?>

表单名为POST，输入名为用户名、密码、电子邮件和提交。
