This is a PHP minimum level error hint, which means that mysql_connect() 被废除 you can precede the code with an @ error suppressor, or the code addserror_reporting(0)

Solve:

@mysql_connect()

Look at this, I am also a copy of the link because do not PHP you try to

PHP's version is too high, the mysql_connect () function will be removed in the future and replaced with mysqli.

Tell the people you're developing. The MySQL-related modules in the PHP project are all changed to mysqli.

As in this line:

 $link = mysqli_connect('localhost', 'user', 'password', 'dbname');

Similar to:

1、mysql_connect 改为mysqli_connect2、mysql_query 改为mysqli_query3、mysql_close 改为 mysqli_close
