Questions about mirroring when PHP connects to SQL Server

Problems with mirroring when PHP connects to SQL Server
A look at the textbook of online database

"SERVER=PARTNER_A; Failover_partner=partner_b; DATABASE=ADVENTUREWORKS2008R2; NETWORK=DBMSSOCN "


Way to connect partner_a when not connected Partner_B




I didn't have a mirrored environment and tried 192.168.1.10 with two identical databases 192.168.1.11
"SERVER=192.168.1.10; failover_partner=192.168.1.11; DATABASE=ADVENTUREWORKS2008R2; NETWORK=DBMSSOCN "

10-way can be connected to 10, 10 off the words will not connect to 11, and no database as

What should I do with the mirror? What else do you need to do with PHP?
