Question

我试图重定向到另一个页面但没有发生任何事情。页面永远不会更改，并且我尝试重定向到的页面的html正在控制台中显示。这有什么理由吗？

代码：

if($bExisitngUser){
/*
 * Set of variables for existing user
 */
 $sUserName = $_POST['sUserName'];
 $sPassword = $_POST['sPassword'];
 $bRememberMe = $_POST['bRememberMe'];

$queryResults = makeLoginRequest('user', $sUserName, $sPassword);
  if($queryResults !== null){
      header('Location: http://www.google.com');
      exit();
  } else{
      header('Location: ../../../ProfilePortal/php/profile.php');
      exit();
  }
}

function conn($sQuery){
    $sMessage = '';
    $db = new mysqli('localhost','root','','myvyn') or die('unable to connect!');
    if($db->connect_errno){
        $message = $db->connect_error;
    } else{
        if($db->query($sQuery)){
            $stmt = $db->prepare($sQuery);
            $stmt->execute();
            $result = $stmt->get_result();
            for($aResult = array(); $row = $result->fetch_assoc(); $aResult[] = $row);
            //print_r($aResult);
            return $row;
        } else{
            $sMessage = $db->error;
            return $sMessage;
        }
    }
}

function makeLoginRequest($table, $id, $pwd){
    $sQuery = "SELECT * FROM `" . $table . "` WHERE `email` = '" . $id . "' AND `password` = '" . $pwd . "'";
    $result = conn($sQuery);
    if(!isset($result)||!defined("$result")||empty($result)||is_null($result)){
        return null;
    } else{
        return $result;
    }
}

在假设编码正确遵循的情况下工作。上面的第一个if语句位于与其余部分不同的php文件中，并且这些代码都不直接在index.php文件中。我也没有回复或打印任何这些文件。

这实际上是控制台中的内容：

请在脚本启动时尝试使用 ob_clean（）函数 此函数丢弃输出缓冲区的内容。

header（）打印到控制台而不是重定向
