I've ruled out the possibility of supplying an incorrect name or password in mysqli_connect, because when I change them to make them incorrect on purpose, I actually get an error message from mysqli_connect_error(). With the code below, the connection fails, but I get no error message. I am out of ideas. What do you recommend I do next to debug?
 <?php
        $con = mysqli_connect("eu-cdbr-west-02.cleardb.net", "b497f08cc1919a", "7d15759b", "heroku_8d537c3a6f00758"); 
        if (!$conn) 
        {
            die("Connection failed: " . mysqli_connect_error());
        }
        echo "Connected successfully";
    ?>
Edit: As Seth pointed out, I mistyped the name of a variable. I'm sorry, I'll see myself out. :(
