Php connection to mysql

Problem Background: My local machine is recorded as: there are multiple servers on the local Intranet: server_aserver_ B: net now localserver_aserver_bnet has issues with mysql and php. This php code is the simplest mysql_connect connection... background:

My local machine logs as: local
Multiple Intranet servers: server_a server_ B
Personal Internet machine: net
Currently, both mysql and php are available on local server_a server_ B net.

This is the problem.

The php code is the simplest mysql_connect connection to the database. The Code is the same.

#->: Request data, =: result: local php-> local mysql => oklocal php-> server_a mysql => errorlocal php-> net mysql => okserver_a php-> server_a mysql => okserver_ B php-> server_a mysql => OK

Why does the local php connection to server_a fail.
The database configuration is exactly the same as the php code.
Could you give me some advice?

Whether your local service is in the same network as the server. If you are not in the same network, you won't be able to access it.
If a network or external port is directly connected, check whether mysql on the server has the permission to enable external access.

Wrong...

Is the CIDR block the same? Is the mysql user %?
