This is a PHP lowest-level error prompt, that isMysql_connect () abolishedBefore the code@Error blocker or codeerror_reporting(0)

Solution:

@mysql_connect()

Look at this. I also copied the link because I don't use php. you can try it.

If the php version is too high, the mysql_connect () function will be removed in the future and replaced by mysqli.

Ask the developer to check that all mysql-related modules in the project's php project are changed to mysqli.

Such as this line:

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

Similar:

1. change mysql_connect to mysqli_connect2, mysql_query to mysqli_query3, and mysql_close to mysqli_close.
