In what ways can PHP beginners improve their debugging skills when troubleshooting database-related issues in their code?

When troubleshooting database-related issues in PHP code, beginners can improve their debugging skills by thoroughly checking their database connection settings, ensuring proper error handling is in place, and utilizing tools like var_dump() or print_r() to inspect variables and query results. 

// Example code snippet for debugging database connection issues
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "myDB";

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

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