Debugging PHP ADODB.Connection - php

Question

I am having a trouble to connect to MS SQL2000 with PHP through COM library.
The message I am getting is:
Could not establish a database connection exception 'com_exception'
with message 'Source: Microsoft OLE DB Provider for ODBC Drivers
Description: [Microsoft][ODBC SQL Server Driver][DBMSLPCN]SQL Server
does not exist or access denied.....
I have read through many posts and couldn't find any straight forward sample how to setup PHP in order to connect easily. These are the steps I've taken so far:
1) running MSSQL2000 with TCP/IP and Named Pipes enabled, listening on port 1433
2) installed PHP Version 5.4.16 TS
3) I have the following extensions enabled (related to mssql):
extension=php_com_dotnet.dll
extension=php_pdo_sqlsrv_53_ts_vc9.dll
extension=php_sqlsrv_53_ts_vc9.dll
extension=php_pdo_mssql.dll
extension=php_pdo_odbc.dll
4) I have checked for the COM windows permissions
5) I am sure I have provided the correct database/instance, username, password for the connection string.
6) when I instantiate the COM object with:
$connection = new COM("ADODB.Connection");
print_r($connection);
...I get the "com Object" output response, meaning the class seems to work fine.
What have I overlooked ? I have to connect through ADODB since the whole site I am working on is build on it. Is there a way to debug this? Any help is appreciated.

PROBLEM SOLVED!
After a few days of figuring this out and reinstalling virtually everything including Apache, different PHP and MSSQL versions I have come up with the following. I am not claiming this to be the best solution but it works:
Functional environment:
1) Windows Azure Server with MSSQL 2012
2) Apache 2.2 PHP 5.3.28 - installer: php-5.3.28-Win32-VC9-x86.msi downloaded from:
http://windows.php.net/download/

The MSSQL 2012 needs to be set as follows:
when creating your database, open the management studio and right click the database instance in the left tree. Make sure that under the properties->security tab you select: "SQL Server and Windows Authentication Mode". Without this you will never connect if you are using the standard username / password method.
Then proceed with creating the database schema and under the main security tab create the new user with username/password related to this database. Make sure you set all permission right i.e: owner, datareader, datawriter.
The PHP connection script I used is as follows:
*===============================================*
function openConnection() {
$dbaseServer = "instance name";
$dbaseIp = "127.0.0.1";
$dbasePort = "1433";
$dbaseName = "databsse name";
$dbaseUser = "username";
$dbasePassword = "password";
$connectionString = ""
."Driver={SQL Server};"
."Network=DBMSSOCN;"
."Server=$dbaseServer;"
."Address=$dbaseIp:$dbasePort;"
."Database=$dbaseName;"
."Uid=$dbaseUser;"
."Pwd=$dbasePassword";
try {
$connection = new COM("ADODB.Connection");
$connection->ConnectionTimeout = 60;
$connection->Open($connectionString);
return $connection;
} catch (exception $e) {
echo "Could not connect - $e";
exit;
}
}
// test query
//===========
$sql = "SELECT * FROM [dbname].[dbo].[tablename]";
$connection = openConnection();
// unnecessary but in my case more time is needed.
$connection->CommandTimeout = 240;
$recordset = $connection->Execute($sql);
if (!$recordset) { $connection->Close(); die("Request failed!"); }
if (!$recordset->EOF) {
while (!$recordset->EOF) {
$test[] = $recordset[0]->value;
$recordset->MoveNext();
}
}
print_r($test);
$connection->Close();

I think that's it. Please feel free to correct my post and/or improve it :)
