Question

好的，所以当我运行此脚本从论坛帖子中删除用户评论时，$ _SESSION [＆＃39; id＆＃39;]（用户的mysql ID）会更改为$ postid（论坛帖子的ID）。我没有调用任何函数来设置它，并且在初始化会话时调用session_write_close();。

<?php
session_start();

// I'm not showing connection code.
if(isset($_SESSION['user'])){

    $user = mysql_real_escape_string($_SESSION['user']);
    $userid = mysql_real_escape_string($_SESSION['id']);

    $id = mysql_real_escape_string($_GET['id']);
    $postid = mysql_real_escape_string($_GET['article']);

    $result = mysql_query("DELETE FROM `______`.`______` WHERE `userid`='$userid' AND `id`='$id' AND `user`='$user'")or die(mysql_error());

    if(mysql_affected_rows($result) == 1){

          mysql_query("UPDATE `_______`.`______` SET `points`=`points`-'1' WHERE `id`='$userid' AND `username`='$user'")or die(mysql_error());
          mysql_query("INSERT INTO `________`.`_______` (`user`,`userid`,`amount`,`reason`) VALUES('$user', '$userid', '-1', 'Removed a comment')")or die(mysql_error());

    }

    mysql_close($con);

    ob_start();
    header("location:../view-article?id=$postid");
    ob_end_flush();

} //if there is a user
else {

    ob_start();
    header("location:http://boundsblazer.com/not-logged-in?url=articles.view-article:id=$postid");
    ob_end_flush();
}
?>

如果register_globals已启用，则此行

$id = mysql_real_escape_string($_GET['id']);

可能会更改$_SESSION['id']的值。所以请在register_globals关闭时再试一次。

PHP $ _SESSION变量随机被覆盖？
