Working code:
$db_host = "";
$db_user = "";
$db_password = "";
$db_dbname = "";
// Create connection
$con = new mysqli($db_host, $db_user, $db_password, $db_dbname);
// Check connection
if ($con->connect_error) {
die("Connection failed: " . $con->connect_error);
}
// Create database
$sql = "CREATE DATABASE dbtest2";
if ($con->query($sql) === TRUE) {
echo "Database created successfully";
} else {
echo "Error creating database: " . $con->error;
}
