What are the potential consequences of having multiple MySQL services running on the same machine?

Having multiple MySQL services running on the same machine can lead to conflicts in port usage, resource contention, and data corruption. To solve this issue, it is recommended to run only one instance of MySQL on a machine and use separate databases within that instance for different applications or environments. 

// Sample PHP code to connect to a specific MySQL database within a single MySQL instance

$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database_name";

// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}
echo "Connected successfully";
