I have a database on my MSSQL server with a '-' in the database name.  The database works fine with all of my other applications including ASP.  However, I cannot select the database with PHP.  Interestingly, a '-' in the server name doesn't seem to be a problem.

$server="SQL-Server";
$dbName="My-DB";
$user="phpusr";
$passwd="phppass";

$hcon = mssql_connect($server, $user, $passwd);
if ($hcon == FALSE)
	die("Could not connect to SQL server '$server'");
$hdb = mssql_select_db($dbName, $hcon);

The resulting message is:

Warning: MS SQL message: Line 1: Incorrect syntax near '-'. (severity 15) in C:\InetPub\PHP\dbtest.php on line 10

Warning: MS SQL: Unable to select database: My-DB in C:\InetPub\PHP\dbtest.php on line 10
Could not select database 'My-DB'
