How can the error handling in PHP be improved to effectively troubleshoot and resolve database-related issues?

To improve error handling in PHP for database-related issues, you can utilize try-catch blocks to catch exceptions thrown by database operations. Within the catch block, you can log the error message or take appropriate action to troubleshoot and resolve the issue.

try {
    // Perform database operations here
} catch (PDOException $e) {
    // Log the error message or take appropriate action
    echo "Database Error: " . $e->getMessage();
}
