PDO_IBM DSN — Connecting to IBM databases
The PDO_IBM Data Source Name (DSN) is based on the IBM CLI DSN. The major components of the PDO_IBM DSN are:
        The DSN prefix is ibm:
.
        
The DSN can be any of the following:
a) Data source setup using db2cli.ini or odbc.ini
b) Catalogued database name i.e. database alias in the DB2 client catalog
             c) Complete connection string in the following format: 
             DRIVER={IBM DB2 ODBC DRIVER};DATABASE=database
;HOSTNAME=hostname
;PORT=port
;PROTOCOL=TCPIP;UID=username
;PWD=password
; 
             where the parameters represent the following values:
             
The name of the database.
The hostname or IP address of the database server.
The TCP/IP port on which the database is listening for requests.
The username with which you are connecting to the database.
The password with which you are connecting to the database.
Example#1 PDO_IBM DSN example using db2cli.ini
The following example shows a PDO_IBM DSN for connecting to an DB2 database cataloged as DB2_9 in db2cli.ini:
$db = new PDO("ibm:DSN=DB2_9", "", "");
[DB2_9]
Database=testdb
Protocol=tcpip
Hostname=11.22.33.444
Servicename=56789
Example#2 PDO_IBM DSN example using a connection string
       The following example shows a PDO_IBM DSN for connecting to an DB2 
       database named testdb
 using the DB2 CLI 
       connection string syntax. 
       
$db = new PDO("ibm:DRIVER={IBM DB2 ODBC DRIVER};DATABASE=testdb;" .
  "HOSTNAME=11.22.33.444;PORT=56789;PROTOCOL=TCPIP;", "testuser", "tespass");
