How can one determine whether PHP is connected to a database using TCPIP or Named Pipe?

To determine whether PHP is connected to a database using TCPIP or Named Pipe, you can check the database connection string in your PHP code. If the connection string contains "tcp:" or "localhost", then it is using TCPIP. If it contains "np:", then it is using Named Pipe. 

// Check the database connection string to determine the connection method
$dsn = "sqlsrv:Server=localhost;Database=myDatabase"; // Example connection string

if (strpos($dsn, "tcp:") !== false || strpos($dsn, "localhost") !== false) {
    echo "PHP is connected to the database using TCPIP.";
} elseif (strpos($dsn, "np:") !== false) {
    echo "PHP is connected to the database using Named Pipe.";
} else {
    echo "Connection method could not be determined.";
}
