Laravel Installation
We will create laravel project using composer. So, please make sure your system should have composer installed. If not, may be this article will help you to Install composer in system.
Here is the command to create a laravel project-
composer create-project --prefer-dist laravel/laravel blog
To start the development server of Laravel –
php artisan serve
URL: http://127.0.0.1:8000
Assuming laravel already installed inside your system.
Concept #1: Store In Default Log File
Laravel default log file location is storage/logs/laravel.log. We are going to store SQL log in the file. But before to store logs we need to do some configuration.
Open AppServiceProvider.php file from app/Providers folder.
<?php
namespace App\Providers;
use Illuminate\Support\ServiceProvider;
use Illuminate\Support\Facades\DB;
use Illuminate\Support\Facades\Log;
class AppServiceProvider extends ServiceProvider
{
/**
* Register any application services.
*
* @return void
*/
public function register()
{
//
}
/**
* Bootstrap any application services.
*
* @return void
*/
public function boot()
{
DB::listen(function ($query) {
Log::info(
$query->sql,
$query->bindings,
$query->time
);
});
}
}
We have added query log logic into boot() method.
Whenever we run any queries by means of using Models, Raw queries, Eloquent, etc will be then automatically queries will be managed into laravel.log file.
Concept #2: Create A Custom Log File
Sometime we may need to create log file with specific task. For example, if someone works with payment task and need all logs at a fixed place, so this concept will help you.
We can create a custom log file to store log data.
Let’s create query.log file in the storage/logs folder. In the boot() method of AppServiceProvider.php file, add this following code –
<?php
namespace App\Providers;
use Illuminate\Support\ServiceProvider;
use Illuminate\Support\Facades\DB;
use File;
class AppServiceProvider extends ServiceProvider
{
/**
* Register any application services.
*
* @return void
*/
public function register()
{
//
}
/**
* Bootstrap any application services.
*
* @return void
*/
public function boot()
{
DB::listen(function($query) {
File::append(
storage_path('/logs/query.log'),
'[' . date('Y-m-d H:i:s') . ']' . PHP_EOL . $query->sql . ' [' . implode(', ', $query->bindings) . ']' . PHP_EOL . PHP_EOL
);
});
}
}
We have added queries log into a custom log file concept into boot() method.
Whenever we run any queries by means of using Models, Raw queries, Eloquent, etc will be then automatically queries will be managed into query.log file. This file will be in /storage/logs folder.
