How do I write to the console from a Laravel Controller?

Solution 1:

Aha!

This can be done with the following PHP function:

error_log('Some message here.');

Found the answer here: Print something in PHP built-in web server

Solution 2:

The question relates to serving via artisan and so Jrop's answer is ideal in that case. I.e, error_log logging to the apache log.

However, if your serving via a standard web server then simply use the Laravel specific logging functions:

\Log::info('This is some useful information.');

\Log::warning('Something could be going wrong.');

\Log::error('Something is really going wrong.');

Or with current version of Laravel, like this:

info('This is some useful information.');

This logs to Laravel's log file located at /laravel/storage/logs/laravel-<date>.log (laravel 5.0). Monitor the log - linux/osx: tail -f /laravel/storage/logs/laravel-<date>.log

• Laravel 4.2: http://laravel.com/docs/4.2/errors

Solution 3:

I haven't tried this myself, but a quick dig through the library suggests you can do this:

$output = new Symfony\Component\Console\Output\ConsoleOutput();
$output->writeln("<info>my message</info>");

I couldn't find a shortcut for this, so you would probably want to create a facade to avoid duplication.

Solution 4:

It's very simple.

You can call it from anywhere in APP.

$out = new \Symfony\Component\Console\Output\ConsoleOutput();
$out->writeln("Hello from Terminal");

Solution 5:

In Laravel 6 there is a channel called 'stderr'. See config/logging.php:

'stderr' => [
    'driver' => 'monolog',
    'handler' => StreamHandler::class,
    'formatter' => env('LOG_STDERR_FORMATTER'),
    'with' => [
        'stream' => 'php://stderr',
    ],
],

In your controller:

use Illuminate\Support\Facades\Log;

Log::channel('stderr')->info('Something happened!');
