How can I implement logging in PHP?

You can use the built-in error_log function or a logging library like Monolog for more advanced features.

What are the benefits of using a logging library?

Logging libraries provide structured logging, different log levels, and better performance for large applications.

Can you show me a simple example using Monolog?

Sure! First, install Monolog via Composer. Then, you can create a logger like this:

use Monolog\Logger;
use Monolog\Handler\StreamHandler;

$log = new Logger('name');
$log->pushHandler(new StreamHandler('path/to/your.log', Logger::WARNING));

$log->warning('This is a warning!');
