How to use event recording SQL query to log in Laravel framework

In this article, we will talk about how to handle query logging in Laravel. If you're very familiar with the Laravel framework, Laravel has the option to log in memory all queries run on the current request.

Query records

If you want to save the log file in the storage/logs directory. Need to update: boot() function in app/Providers/AppServiceProvider.php.

<?php namespace App\Providers;

use Illuminate\Support\ServiceProvider;
use DB;

class AppServiceProvider extends ServiceProvider
{
    /**
     * Bootstrap any application services.
     *
     * @return void
     */
    public function boot()
    {
        // 新增代码
        DB::listen(function($query) {
            Log::info(
                $query->sql,
                $query->bindings,
                $query->time
            );
        });
    }
    /**
     * Register any application services.
     *
     * @return void
     */
    public function register()
    {
        //
    }
}

This way we can record the executed SQL statements, and it is also convenient for us to debug during the development process.
