Question

我正在学习编写一个从SQL server获取user_status的函数。我通常使用mysqli数据库并在PHP中编写代码：

function fetchuserStatus($username,$password){
  global $mysqli;
  $stmt = $mysqli->prepare("SELECT user_status from table_name where username = ? AND password = ?");
  $stmt->bind_param("ss",$username,$password);
  $stmt->execute();
  $stmt->bind_result($userstatus);
  $stmt->store_result();
  $stmt->fetch();
  $stmt->close();
  return $userstatus;
}

现在我想为SQL SERVER编写相同内容。我怎样才能做到这一点？因为我与SQL SERVER建立连接，这是为sql server编写代码的最佳方法。

注意：我使用的是PHP 7.1

提前致谢。

查看PHP sql server文档http://php.net/manual/en/book.sqlsrv.php

但是如果我们要把它翻译成sql server。

function fetchuserStatus($username,$password){
  $conn = sqlsrv_connect('localhost', array("Database"=>"USERS_TBL", "UID"=>"dbuser", "PWD"=>"dbpassword");
  if ($conn) {
      $sql = "SELECT user_status from table_name where username = ? AND password = ?");
      $parameters = array($username,$password);
      $stmt = sqlsrv_query($conn, $sql, $parameters);
      if(sqlsrv_has_rows($stmt) === true) {
          sqlsrv_fetch($stmt);
          /*
           Use results however you want
           You can get results using sqlsrv_get_field($stmt, 0);
           0 is the index of the column on your select, if you selected something after user_status then that column would be 1 
          */
      }
      sqlsrv_free_stmt($stmt);
      sqlsrv_close($conn);
  }
}

为SQL SERVER 2014编写函数的最佳方法
