PDO连接到MS SQL Server 2008

Question

I have done this once before in a VM, however, I needed to create a second instance of a VM, and I am trying to connect to my MS SQL Server. Currently I have php-5.3.6-nts-Win32-VC9-x86 version of php installed. I have correctly configured my php.ini and running phpinfo() I can verify that I have sqlsqrv PDO drivers installed correctly. I am using this in conjunction with IIS 7, and I have the webserver up and running. I have the following line in my index.php file

$conn = new PDO("sqlsrv:server=$serverName; Database=classReg");

I also have the following to give me some feedback on if I made a successful connection to the database.

if($conn) {
    echo "Connection established. </br></br>";
} else {
    echo "Connection could not be established. </br>";
    die(print_r(sqlsrv_errors(), true));
}

Problem is, I'm not getting anything out of my $conn variable. I've tried to echo that variable, and I'm not getting any feedback.

FWIW my php.ini file reads these three lines at the end of the file

[PHP_MS_SQL_PDO]
extension=php_sqlsrv_53_nts_vc9.dll
extension=php_pdo_sqlsrv_53_nts_vc9.dll

Any ideas as to what I may be missing?

Answer 1

I was able to fix the issue by doing the following:

• I created a user to access the database with in place of Windows Authentication.
• I also added IUSR to the database logins group.

After doing those two things, I modified the following line of code to connect to the database.

$conn = new PDO("sqlsrv:server=$serverName; Database=classReg");

This line now reads:

$conn = new PDO("sqlsrv:server=$serverName; Database=classReg", "<user>", "<password>");

One thing that helped me out was looking at the logs for the server. I was having an issue, because I wasn't getting any output from my if statement in the original code. But I was able to look at the logs from SQL Server, and I was able to see what was happening. The logs are located at Management -> SQL Server Logs . After I made those two changes, I was able to successfully connect to the database without any troubles. I hope this helps anyone else that is running into an issue like this!
