Php 设置从本地主机到服务器的服务器代码
我一直在试着运行一些代码 代码可以在下一个链接中找到 正如您所看到的，它有一个客户端和一个服务器代码，这是一个基于套接字通信的android即时通讯器 服务器代码包含三个文件——一个sql文件和两个php文件 问题是，当我使用XAMPP作为本地主机测试代码时，一切都很好 当我试图将其移动到服务器时，问题就出现了 我所做的很简单——我在serversfree.com上开了一个账户。然后我转到MySQL数据库，创建了一个数据库名：和用户名。之后，我上传了sql文件 然后我转到文件管理器选项，并将index.php和mysql.class.php上传到它。我还在index.php文件中编辑了四行相关内容-Php 设置从本地主机到服务器的服务器代码,php,android,mysql,sql,sockets,Php,Android,Mysql,Sql,Sockets,我一直在试着运行一些代码 代码可以在下一个链接中找到 正如您所看到的，它有一个客户端和一个服务器代码，这是一个基于套接字通信的android即时通讯器 服务器代码包含三个文件——一个sql文件和两个php文件 问题是，当我使用XAMPP作为本地主机测试代码时，一切都很好 当我试图将其移动到服务器时，问题就出现了 我所做的很简单——我在serversfree.com上开了一个账户。然后我转到MySQL数据库，创建了一个数据库名：和用户名。之后，我上传了sql文件 然后我转到文件管理器选项，并将in
$dbHost = "";
$dbUsername = "DBUSERNAME";
$dbPassword = "DBPASSWORD";
$dbName = "DBNAME";
问题是，例如，当一个用户试图注册时——当我在本地主机上尝试时，一切正常，但在服务器上——在客户端，它告诉用户出了问题，注册失败了——但是当我查看mySQL表时，我可以看到用户信息确实进入了表中，甚至我也可以用用户信息登录 我遇到的另一个问题是，当一个用户试图将另一个用户添加到他的联系人列表中时，它肯定不起作用。 即使当我转到mySQL表并将值从0更改为1时（好像说好友请求已被批准），用户名仍然不会显示在好友列表中。在本地主机场景中，这一点确实有效 我希望这里有人能帮我弄清楚是什么造成了这个问题 当我按下注册按钮时，这是android的日志-

我们很好地发现了这个问题，像-serversfree.com或000webhost.com这样的免费托管网站正在向代码中添加一个分析代码
为了克服这个问题，000webhost的解决方案如下-
在文件管理器的[public_html]中，您需要创建一个名为[.htaccess]的文件
你需要在里面打字-
<FilesMatch "\.(php)$">
php_value auto_append_file none
</FilesMatch>
php_值自动_追加_文件无
这将防止所有.php文件都附加分析代码。只需将[php]替换为您希望删除分析代码的任何文件扩展名
为了防止您的域被取消，请不要通过转到下一个链接来禁用您的分析代码-
编辑-
这也适用于
