How can PHP developers effectively debug and troubleshoot their code?

To effectively debug and troubleshoot PHP code, developers can use tools like Xdebug to set breakpoints, step through code, and examine variables. They can also use error reporting functions like error_reporting() and ini_set() to display errors and warnings. Additionally, developers can utilize logging libraries like Monolog to track the flow of their code and identify issues. 

// Enable error reporting
error_reporting(E_ALL);
ini_set('display_errors', 1);

// Implement logging with Monolog
use Monolog\Logger;
use Monolog\Handler\StreamHandler;

$log = new Logger('debug');
$log->pushHandler(new StreamHandler('path/to/logfile.log', Logger::DEBUG));

$log->info('This is an informational message');
$log->error('This is an error message');
