How to connect to a mysql server with multihost?

Question

In PHP, How to connect to a mysql server with multihost ?

In this picture, it's just an exemple my host in my server is "Database_Server_2" not "Database Server 2" and i have a port "81"

I try this code, but i don't work :/

 $link = mysql_connect('localhost:81/Database_Server_2', 'db_user', '******');

Answer 1

you can not connect multiple host in one connection, you have to use resource identifier($link) to manage connection like:

$link1 = mysql_connect('localhost:81/Database_Server_2', 'db_user', '******');
$link2 = mysql_connect('localhost:81/Database_Server_2', 'db_user', '******');

also mysql_connect will be deprecate very soon, use mysqli or PDO, they also better in performance.

Answer 2

MySQL does not support such named instances. The name "Database Server 2" is most probably only a name given to it in the phpMyAdmin config file, so you don't have to bother with remembering which IP/Port is which.

Look in the config file of phpMyAdmin, the second instance will be using a different port than the first instance. Just providing the port should work.

$link = mysql_connect('localhost:81', 'db_user', '******');

And the usual note: mysql_ functions are deprecated and will be removed from PHP in future versions. You should not write new code using them, use mysqli_* or PDO instead.
