如何克隆 mysql_result

发布于 2024-11-16 20:34:31 字数 729 浏览 0 评论 0原文

我会解释我的问题从index.php我发布我的登录信息，并在login.php中我存储会话详细信息（如名称），例如：

$_SESSION['name'] =  mysql_result($res,0,"name");

然后我被转发回index.php。在这里，我想显示登录用户的名称：

   echo $_SESSION['name']

以及数据库中的所有名称：

$result=mysql_query($query);
for ($i=0; $i<mysql_num_rows($result); $i++) {
  $row = mysql_fetch_assoc($result);
  $name =$row['name']; 
  echo $name;
}

问题来了：登录后，所有内容（用户名和所有名称）都正确显示。但是当我刷新页面时 echo $_SESSION['name'] 显示数据库中的姓氏 == $name 而不是原来的

所以我想我需要存储到 $_SESSION['name'] 时克隆 mysql_result($res,0,"name");

非常感谢您

编辑我在会话中存储的唯一内容是登录名。当该人登录时，他可以看到数据库中的所有人员。

I will explain my problem
From index.php I POST my login and in login.php I store session details (like name) e.g.:

$_SESSION['name'] =  mysql_result($res,0,"name");

then I am forwarded back to index.php.
Here I want to show logged-in-user's name:

   echo $_SESSION['name']

and also all names from the DB:

$result=mysql_query($query);
for ($i=0; $i<mysql_num_rows($result); $i++) {
  $row = mysql_fetch_assoc($result);
  $name =$row['name']; 
  echo $name;
}

And here comes the problem: after I log in, everything (both user's name and all names) is displayed correctly. But when I refresh the page echo $_SESSION['name'] shows the last name in the databse == $name instead of the one that was

So I guess I need to clone mysql_result($res,0,"name"); when storing into $_SESSION['name']

Thank you very much

EDIT
the only thing i store in session is the login name. And when the person is logged-in he can see all people from database.

如果您正在寻找克隆对象，那么您可以尝试以下操作

$object2 = clone $object1;

从 php 文档看来，某些对象不支持克隆，因此如果是这种情况，那么您可以尝试以下操作（同样，来自 php 文档中的注释）进行深层复制

protected function deepCopy($inputObject) {
    return unserialize(serialize($inputObject)); 
}

文档页面的注释中还提出了一些其他好的观点，可以在此处找到 http://php.net/manual/en/language.oop5.cloning.php

致以诚挚的问候

If you are looking to clone an object then you can try the following

$object2 = clone $object1;

From the php documentation it seems that some objects do not support cloning, so if this is the case then you could try the following (again, from comment in php documentation) to do a deep copy

protected function deepCopy($inputObject) {
    return unserialize(serialize($inputObject)); 
}

There are some other good points made in the comments of the documentation page which can be found here http://php.net/manual/en/language.oop5.cloning.php

Best regards
