问题描述

I got this warning message when executing my PHP script in Internet webserver, but in local wamp it is working without warnings. what is the reason ?

Warning: mysql_real_escape_string() [function.mysql-real-escape-string]: A link to the server could not be established in /home/deport/public_html/abc/index.php on line 209

推荐答案

mysql_real_escape_string()需要与MySQL服务器的活动连接，如果没有，将使用php.ini配置中的默认数据来启动一个.

mysql_real_escape_string() needs an active connection to the MySQL server and will initiate one with the default data from the php.ini configuration if there is none.

在未首先连接到数据库之前，请勿使用此功能.

Do not use this function without first connecting to the database.

也不要使用mysql_ *函数.它们已弃用，将从PHP中删除.

Also, do not use the mysql_* functions. They are deprecated and will be removed from PHP.
