How can error handling and debugging techniques be applied effectively in PHP code to troubleshoot issues related to session management and database storage?

Issue: To troubleshoot issues related to session management and database storage in PHP code, it is essential to implement proper error handling and debugging techniques. This includes using functions like error_reporting() to display errors, using try-catch blocks to catch exceptions, and utilizing tools like Xdebug for more in-depth debugging. 

// Set error reporting level to display all errors
error_reporting(E_ALL);

// Example of using try-catch block for database connection
try {
    $pdo = new PDO('mysql:host=localhost;dbname=mydatabase', 'username', 'password');
} catch (PDOException $e) {
    echo "Database connection failed: " . $e->getMessage();
}

// Example of debugging session management
session_start();
$_SESSION['test'] = 'test';
echo $_SESSION['test'];
