使用 PDO 连接 IBM 数据库

I tried connect IBM database through PDO using below code. But, it is not working

try {
    $db = new PDO("odbc:DRIVER={IBM DB2 ODBC DRIVER};DATABASE=BLUDB;HOSTNAME=hostname;PORT=50000;PROTOCOL=TCPIP;", "username", "password");
    echo "<pre>";
    print_r($db);
    exit;
} catch (PDOException $e) {
    echo $e->getMessage();
}

I got below error for the same

SQLSTATE[IM002] SQLDriverConnect: 0 [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified

I have also added below code in php.ini file

extension=php_pdo.dll
extension=php_pdo_ibm.dll
extension=php_ibm_db2.dll

Could anyone suggest me, how I can connect with IBM database?

there is different driver name for some computer, this is the list of driver you can try:

• DRIVER={iSeries Access ODBC Driver};
• DRIVER={IBM i Access ODBC Driver};

and try to use System instead of HOSTNAME

DRIVER={iSeries Access ODBC Driver};DATABASE=BLUDB;System=hostname;PORT=50000;PROTOCOL=TCPIP;

oh, and I'm using DRIVER={IBM i Access ODBC Driver};
