sqlsrv_connect: Data source name not found and no default driver specified

问题

I am facing difficulties in connecting PHP with SQL SERVER 2008 running on a remote computer. I have php version 5.4.3 and apache 2.2.22. I already have SQL SERVER 2008 running on my computer. I have following files included in my wamp\bin\php\php5.4.3\ext folder:

php_sqlsrv_54_ts.dll
php_pdo_sqlsrv_54_ts.dll

On running simple code like

$conn = sqlsrv_connect( $serverName, $connectionInfo);

if( $conn )
{
 echo "Connection established.\n";
}
else
{
 echo "Connection could not be established.\n";
 die( print_r( sqlsrv_errors(), true));
}

I am getting following error:

Connection could not be established. Array (
    [0] => Array (
        [0] => IMSSP [SQLSTATE] => IMSSP
        [1] => -49 [code] => -49
        [2] => This extension requires the Microsoft SQL Server 2012 Native Client. Access the following URL to download the Microsoft SQL Server 2012 Native Client ODBC driver for x86: http://go.microsoft.com/fwlink/?LinkId=163712 [message] => This extension requires the Microsoft SQL Server 2012 Native Client. Access the following URL to download the Microsoft SQL Server 2012 Native Client ODBC driver for x86: http://go.microsoft.com/fwlink/?LinkId=163712
    )

    )
)

But I dont know why I am being asked for Microsoft SQL Server 2012 Native Client installation.

phpI have tried this link but with no success.

Thanks in Advance.

UPDATE 1:

I downloaded php 5.3.1 and followed this tutorial and scripts works like a charm.

回答1:

According to requirements: The SQLSRV extension requires that the Microsoft SQL Server 2012 Native Client be Installed on the same Computer that is running PHP.

回答2:

Install ODBC Driver(https://www.microsoft.com/en-us/download/details.aspx?id=36434). Now I can Access the remote MSSQL Server without installing the MSSQL Server in my computer
