A deep dive into the logging process in Laravel
Laravel is an open source PHP web application framework, known as an elegant web application framework. It provides many useful tools and functions, one of the important functions is logging. Logging is an important tool for recording system events and troubleshooting. In the Laravel framework, developers can easily log and store various events and errors for their applications. This article takes an in-depth look at the logging process in Laravel.
What is Laravel logging?
In Laravel, logging is a configurable process of recording system events, including application errors, debugging information, performance and access logs, etc. It is an essential part of application development and can track and resolve various issues to ensure the smooth running of the application.
Laravel supports many different types of log drivers (Log Driver), including files, databases, Syslog, FirePHP, Monolog, Slack, etc. Using these drives, developers can log to a variety of different locations, such as local disks, network storage, cloud platforms, and more.
Laravel logging configuration
Laravel provides a default Monolog logger (Logger) that can be easily used by developers. Different logging options can be configured in Laravel's configuration file, such as the path to the log file, drive type, log level, etc. All options related to logging can be found in Laravel's config/logging.php
configuration file.
The following are some commonly used log options:
- driver: Specify the log driver. Laravel supports many different types of log drivers, including file, database, Syslog, FirePHP, Monolog, Slack, and more.
- path: Specify the file path of the log record. If using a file drive, you can specify the path to the logging file.
- level: Specify the log level allowed to be recorded, such as debug, info, warning, error, critical, alert, etc.
- channel: Specify the channel name used for logging. Different channels can be defined in the configuration file to record different logs.
Laravel Logging Example
Let’s see how to log using Laravel.
First, in the controller or Service, you can use the Log
facade to record events, warnings, errors, etc. in the application.
use Illuminate\Support\Facades\Log; class MyController extends Controller { public function index(Request $request) { // 记录一个 debug 日志 Log::debug('debug message', ['user' => $request->user()]); // 记录一个 error 日志 Log::error('error message', ['error' => 'something wrong']); return view('welcome'); } }
In the log file, the recorded logs will be packed into separate files according to date. For example, suppose we record two log events in our application on September 10, 2022, one is the debug log and the other is the error log. A log file named laravel-2022-09-10.log is created on the local disk. This file is split into sections by date, making it easy to track and view log events for a specific date.
# laravel-2022-09-10.log [2022-09-10 00:00:00] local.DEBUG: debug message {"user":1} [2022-09-10 00:00:00] local.ERROR: error message {"error":"something wrong"}
In the above log file, we can see the details of the two log events, including date and time, log level, log message, and other custom information.
Summary
Logging is a very important part of the development process. Laravel provides a powerful logging system to help developers quickly record events and troubleshoot. In this article, we've covered the basics of Laravel logging, configuration options, and examples, which we hope will help you better understand the Laravel logging system.

Create referrals table to record recommendation relationships, including referrals, referrals, recommendation codes and usage time; 2. Define belongsToMany and hasMany relationships in the User model to manage recommendation data; 3. Generate a unique recommendation code when registering (can be implemented through model events); 4. Capture the recommendation code by querying parameters during registration, establish a recommendation relationship after verification and prevent self-recommendation; 5. Trigger the reward mechanism when recommended users complete the specified behavior (subscription order); 6. Generate shareable recommendation links, and use Laravel signature URLs to enhance security; 7. Display recommendation statistics on the dashboard, such as the total number of recommendations and converted numbers; it is necessary to ensure database constraints, sessions or cookies are persisted,

Create a new Laravel project and start the service; 2. Generate the model, migration and controller and run the migration; 3. Define the RESTful route in routes/api.php; 4. Implement the addition, deletion, modification and query method in PostController and return the JSON response; 5. Use Postman or curl to test the API function; 6. Optionally add API authentication through Sanctum; finally obtain a clear structure, complete and extensible LaravelRESTAPI, suitable for practical applications.

Laravel supports the use of native SQL queries, but parameter binding should be preferred to ensure safety; 1. Use DB::select() to execute SELECT queries with parameter binding to prevent SQL injection; 2. Use DB::update() to perform UPDATE operations and return the number of rows affected; 3. Use DB::insert() to insert data; 4. Use DB::delete() to delete data; 5. Use DB::statement() to execute SQL statements without result sets such as CREATE, ALTER, etc.; 6. It is recommended to use whereRaw, selectRaw and other methods in QueryBuilder to combine native expressions to improve security

The Repository pattern is a design pattern used to decouple business logic from data access logic. 1. It defines data access methods through interfaces (Contract); 2. The specific operations are implemented by the Repository class; 3. The controller uses the interface through dependency injection, and does not directly contact the data source; 4. Advantages include neat code, strong testability, easy maintenance and team collaboration; 5. Applicable to medium and large projects, small projects can use the model directly.

EloquentORM is Laravel's built-in object relational mapping system. It operates the database through PHP syntax instead of native SQL, making the code more concise and easy to maintain; 1. Each data table corresponds to a model class, and each record exists as a model instance; 2. Adopt active record mode, and the model instance can be saved or updated by itself; 3. Support batch assignment, and the $fillable attribute needs to be defined in the model to ensure security; 4. Provide strong relationship support, such as one-to-one, one-to-many, many-to-many, etc., and you can access the associated data through method calls; 5. Integrated query constructor, where, orderBy and other methods can be called chained to build queries; 6. Support accessors and modifiers, which can format the number when obtaining or setting attributes.
