How to log data in JSON in Laravel

Logging data in JSON format in Laravel can be done using the built-in Monolog logging library that Laravel uses under the hood.

Here are the steps to configure Laravel to log data in JSON format:

1. Open the config/logging.php file in your Laravel project.
2. In the channels array, create a new channel for logging in JSON format:

'json' => [
    'driver' => 'daily',
    'path' => storage_path('logs/laravel.json'),
    'level' => 'debug',
    'days' => 14,
],

This configuration sets up a new channel named json that logs data in a daily rotating file located in the storage/logs directory with a name laravel.json. The logging level is set to debug and logs will be retained for 14 days.

1. Update the stack channel to include the json channel:

'stack' => [
    'driver' => 'stack',
    'channels' => ['single', 'json'],
],

This will ensure that logs are written to both the default single channel (which logs in plain text) and the new json channel.

1. Use the Log facade to log data in JSON format:

Log::channel('json')->debug(json_encode(['key' => 'value']));

This will log a JSON object in the json channel.

With these steps, Laravel will now log data in JSON format in addition to the default plain text format.
