Extending PHP Function Logging with Laravel

Extending PHP Function Logging with Laravel

Laravel provides a concise way to extend PHP function logging, allowing you to easily add support for custom logging in your application.

Installation

Install the monolog/monolog package via Composer:

composer require monolog/monolog

Configuration

Add the following configuration to config/logging.php :

'channels' => [
    'custom' => [
        'driver' => 'monolog',
        'handler' => 'custom',
        'formatter' => env('LOG_CUSTOM_FORMATTER', 'default'),
        'level' => env('LOG_CUSTOM_LEVEL', 'debug'),
    ],
],
'handlers' => [
    'custom' => [
        'type' => 'monolog',
        'path' => env('LOG_CUSTOM_PATH', storage_path('logs/custom.log')),
    ],
],

Usage

Use the \Illuminate\Support\Facades\Log facade to write custom logs:

Log::channel('custom')->debug('Custom log message');

Practical Example

Create a middleware to log API request and response details, including method, URI, and execution duration:

class ApiRequestLogMiddleware
{
    public function handle($request, $next)
    {
        $start = microtime(true);

        $response = $next($request);

        $duration = microtime(true) - $start;
        Log::channel('api')->info('Request: {method} {uri} - Duration: {duration} ms', [
            'method' => $request->method(),
            'uri' => $request->uri(),
            'duration' => round($duration * 1000, 2),
        ]);

        return $response;
    }
}
