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");
