Connecting to DB w/ MDB2

I previously followed a tutorial for DB abstraction using PEAR

B and everything worked fine until this last weekend. I'm not quite sure what happened but most logs point to an upgrade of the MySQL server I'm using as a backend. Anyway I noticed the package "DB" was superseeded by MDB2 anyway so I tried to upgrade my code to the new format and am having problems. Please help!

Here are my installed PEAR packages -

Installed packages, channel pear.php.net:
=========================================
Package Version State
Archive_Tar 1.3.1 stable
Console_Getopt 1.2 stable
DB 1.7.6 stable
HTTP 1.2.2 stable
MDB2 2.0.3 stable
MDB2_Driver_mysql 0.2.3 beta
Mail 1.1.10 stable
Mail_Mime 1.3.1 stable
Net_SMTP 1.2.6 stable
Net_Socket 1.0.1 stable
OLE 0.5 beta
PEAR 1.4.6 stable
Spreadsheet_Excel_Writer 0.9.0 beta
XML_Parser 1.0.1 stable
XML_RPC 1.1.0 stable

I'm using Debian 3.1 (Sarge) and PHP4.

Here is my config file:

php Code:

Original - php Code

 
/** Database Configuration */
//require the PEAR::DB classes.
 
// require_once 'DB.php';
require_once 'MDB2.php';
 
$db_engine = 'mysql';           //mysql = MySQL, pgsql = PostgreSQL, mssql = Microsoft SQL Server
$db_user = 'user';   //Username
$db_pass = 'pass';   //Password
$db_host = 'localhost';         //Host
$db_name = 'db_name';   //Database name
 
$datasource = $db_engine.'://'.
                          $db_user.':'.
                          $db_pass.'@'.
                          $db_host.'/'.
                          $db_name;
 
$db_object = MDB2::connect($datasource, TRUE);
 
// assign database object in $db_object,
// if the connection fails $db_object will contain
// the error message.
 
// If $db_object contains an error:
// error and exit.
 
if(PEAR::isError($db_object)) {
        die($db_object->getMessage());
}
 
$db_object->setFetchMode(DB_FETCHMODE_ASSOC);

Is this correct and how should I call it?

This may work

I just found this, and although it's a very old thread, I thought I would still give my input (since it still shows up on Google and I just had the same problem).

I was using PostgreSQL, however- but my problem was similar in the sense that nothing seemed wrong but I still could not connect... this is what solved it for me:

I set localhost(80) as the host. I think this is to explicitly tell it to connect using port 80, which may be a restriction set in place for that particular DB user, as it appears to have been for me.

Try it if you still have, or end up again experiencing, that problem. It may work for you.

Forgive me if I am off-base in my explanation of this solution... I am still relatively new to DSN and DB abstraction layers.
