Customize Laravel error reporting to remove stack trace - php

Question

How can you turn off or remove the stack traces from Laravel's error reports. They're annoying if you want to read them in your console. I know you can add a custom handler in app/Exceptions/Handler.php, but I have no idea how to do that.

Answer 1

Setting APP_DEBUG=false in your .env file works fine for the frontend.
If you don't want the stack trace lines to be outputted in the log files only, try this.
In /app/Exceptions/Handler.php add use Log; at the top, then add this in the report function:
Log::error('['.$e->getCode().'] "'.$e->getMessage().'" on line '.$e->getTrace()[0]['line'].' of file '.$e->getTrace()[0]['file']);
And remove:
parent::report($e);

Since I can not comment on or edit #Harold answer, here is a improved sollution:
In /app/Exceptions/Handler.php add use Log; at the top,
Then modify the report function:
public function report(Exception $e)
{
if (!config('app.debug')) {
Log::error('['.$e->getCode().'] "'.$e->getMessage().'" on line '.$e->getTrace()[0]['line'].' of file '.$e->getTrace()[0]['file']);
} else {
parent::report($e);
}
}

For those who don't like "add this, remove that" kind of instructions, here's what app/Exceptions/Handler.php should look like, based on Laravel 5.7, and sticking to a message format like PHP's native one:
<?php
namespace App\Exceptions;
use Log;
use Exception;
use Illuminate\Foundation\Exceptions\Handler as ExceptionHandler;
use Illuminate\Auth\AuthenticationException;
class Handler extends ExceptionHandler
{
/**
* A list of the exception types that are not reported.
*
* #var array
*/
protected $dontReport = [
//
];
/**
* A list of the inputs that are never flashed for validation exceptions.
*
* #var array
*/
protected $dontFlash = [
'password',
'password_confirmation',
];
/**
* Report or log an exception.
*
* #param \Exception $exception
* #return void
*/
public function report(Exception $exception)
{
Log::error(sprintf(
"Uncaught exception '%s' with message '%s' in %s:%d",
get_class($exception),
$exception->getMessage(),
$exception->getTrace()[0]['file'],
$exception->getTrace()[0]['line']
));
// parent::report($exception);
}
/**
* Render an exception into an HTTP response.
*
* #param \Illuminate\Http\Request $request
* #param \Exception $exception
* #return \Illuminate\Http\Response
*/
public function render($request, Exception $exception)
{
return parent::render($request, $exception);
}
}
Note that you can replace Log::error() with a simple call to error_log() to write to PHP's standard error log. If you do that, you don't have to remove the call to parent::report(). That way you can keep the traces in the Laravel log for further debugging, but keep your main PHP log for quick checks.

Another way is to edit the log format in your logging config file. This means you don't have to override the default report function which would mean missing out on other logic within the parent function.
I set mine to this:
'daily' => [
'driver' => 'daily',
'formatter' =>LineFormatter::class,
'formatter_with' => [
'format' => "[%datetime%] %channel%.%level_name%: %message%\n %context%\n",
'dateFormat' => "Y-m-d H:i:s"
],
'path' => storage_path('logs/laravel.log'),
'level' => env('LOG_LEVEL', 'debug'),
'days' => 14,
],

Answer 5

simplely set your APP_DEBUG=false in your env file.

Answer 6

Harold and Jani's answers are correct.
However the log line is less detailed than the default one.
The best solution would be to edit the file:
vendor/laravel/frameworks/src/Illuminate/Log/LogManager.php
and add false argument when the includeStacktraces method is called.
add false to
$formatter->includeStacktraces();
so:
$formatter->includeStacktraces(false);
This will simply disable the stacktrace. Everything else remains the same.
