DB2 PHP Connection

Question

Been digging through stackoverflow for a few days now. Need to connect to a DB2 database with PHP. The following code doesn't return the error message or any helpful information, and instead just breaks Javascript later in the page.

include(TEMPLATEPATH.'/inc/library/adodb_lite/adodb.inc.php'); 
   $DBName = 'DBNAME';
   $Host = 'IPADDRESS';
   $User = 'USER';
   $Password = 'PASS';

   $db = ADONewConnection('db2');

   $dsn = "driver={IBM db2 odbc DRIVER};Database=$DBName;hostname=$Host;protocol=TCPIP;uid=$User;pwd=$Password";
     if ($db->Connect($dsn)) {
     echo "<div style='color:green;font-size:21px;'>Connection Successful.</div>";
             } else {
                 echo "<div style='color:#cc0000;font-size:21px;'>Connection Failed db->Connect(dsn)</div>";
                 echo 'SQLSTATE: '.$db->ErrorNo()."<br>";
                 echo 'Message: '.$db->ErrorMsg()."<br>";
             }

Answer 2

My thought is that your driver name doesn't match what you have in your odbcinst.ini file. Here's what I'm using:

odbcinst.ini

[iSeries Access ODBC Driver]
Description     = iSeries Access for Linux ODBC Driver
Driver          = /usr/lib/libcwbodbc.so
Setup           = /usr/lib/libcwbodbcs.so
NOTE1           = If using unixODBC 2.2.11 or later and you want the 32 and 64-bit ODBC drivers to share DSN's,
NOTE2           = the following Driver64/Setup64 keywords will provide that support.
Driver64        = /usr/lib/lib64/libcwbodbc.so
Setup64         = /usr/lib/lib64/libcwbodbcs.so
Threading       = 2
DontDLClose     = 1
UsageCount      = 1

Note that the "name" of this driver is defined to be "iSeries Access ODBC Driver" - whatever you put between the brackets [].

Now my PHP code looks like this:

$this->db_connection = new PDO("odbc:DRIVER={iSeries Access ODBC Driver};SYSTEM=$this->he_database_server;PROTOCOL=TCPIP", $temp_username, $temp_password);

So check to make sure your driver name (IBM db2 odbc DRIVER) is the same in your odbcinst.ini file.

Now if that doesn't solve the problem I would recommend you turn on ODBC logging by adding the following to your odbcinst.ini file:

[ODBC]
TraceFile = /tmp/odbc.log
Trace = Yes

That will write out a lot of information to a log file and give you a good idea of what's wrong. If that still doesn't get it working my only other suggestions are the most basic of things: make sure the username/password is correct, the AS/400 is reachable from the server running PHP, etc.
