How can error reporting be optimized in PHP to debug issues related to database connections and queries?

When debugging database connection and query issues in PHP, it is essential to optimize error reporting to provide detailed information about the problem. One way to achieve this is by setting the error reporting level to display all errors, warnings, and notices related to database operations. This can be done by configuring PHP settings or using functions like error_reporting() and ini_set(). 

// Enable error reporting for database connection and query issues
error_reporting(E_ALL);
ini_set('display_errors', 1);

// Sample database connection code
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

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

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

// Sample database query code
$sql = "SELECT * FROM table";
$result = $conn->query($sql);

if (!$result) {
    die("Query failed: " . $conn->error);
}

// Process query results...
