Error 08001 while connecting to SQL Server by using PHP - php

Question

Here is my problem, I have my connection handles like this:
$dbSrvName = 'servername';
$dbName = 'database';
$dbUser = 'user';
$dbPass = 'password';
$dbInfo = array(
'Database' => $dbName,
'UID' => $dbUser,
'PWD' => $dbPass
);
$this->dbConn = sqlsrv_connect($dbSrvName, $dbInfo);
if(!$this->dbConn)
{
die(print_r( sqlsrv_errors(), true), 1);
}
When I trigger output from sqlsrv_errors() I get the following message:
Array ( [0] => Array ( [0] => 08001 [SQLSTATE] => 08001 [1] => 26
[code] => 26 [2] => [Microsoft][SQL Server Native Client 10.0]Client

SQLSRV USED:
php_sqlsrv_53_ts_vc9.dll
So I am afraid the version of SQL is not compatible with this version of sqlsrv. Any ideas?
Thank you in advance and Happy New Year!

Answer 1

I am going to guess you are trying to remotely connect to the sql server. You need to make sure that is actually possible with your sql server configuration.
Then you need to make sure that the user account you are trying to connect with has proper permissions
Then firewall needs to be opened as well on the server...
here is a short list of things to check.
Can't Connect Remotely

Answer 2

Actually, it was a misunderstanding! The database that I was trying to connect to is Oracle. So the PHP library is not compatible.
Thanks anyway...
