How do I hash passwords securely in Yii?
To have the password safely in Yii, use the built-in security assistance method of Yii. 1. Use Yii::$app->security->generatePasswordHash() to hash the user password. The bcrypt algorithm is used by default, and the unique salt value is automatically added. The calculation cost parameters can be optionally adjusted. 2. Store the generated hash value to the database, and the recommended field length is at least 60 characters. 3. When the user logs in, use Yii::$app->security->validatePassword() to safely verify whether the input password matches the storage hash, and avoid direct comparison or manual extraction of salt values. 4.

Using Config Helper | Accessing Configuration Values
ConfigHelper is a helper class or function that encapsulates configuration read logic for extracting values ??from configuration files and improving code maintainability. 1. It avoids hard coding through centralized management of configurations; 2. It can be implemented as an extended structure that supports multi-level, cache, encryption and other functions; 3. Common configuration storage methods include .env files, JSON/YAML files, databases and environment variables; 4. When using it, the configuration files should be split reasonably, the default values ??should be provided, sensitive information should be distinguished, and the caching mechanism should be paid attention to.

Monitoring Queued Jobs Telescope | Queue Inspection
To monitor queued tasks in Laravel's Telescope, you need to manually add the listening event. 1. Open the app/Providers/TelescopeServiceProvider.php file; 2. Introduce and listen to the JobQueued event in the register() method; 3. After the configuration is completed, you can view the detailed information of the queuedjob under the Jobs tag of Telescope, including the task class name, queue name and enqueue parameters. This method is suitable for Redis or database-driven queues and supports monitoring of delayed tasks. Note that filtering rules and data security policies should be set reasonably in the online environment to avoid performance problems and sensitive information

Using Laravel Collections | Powerful Data Handling
LaravelCollections provides a smooth, object-oriented way to process array data, with its core advantage simplifying data filtering, transformation and aggregation operations. 1. Use where(), filter() and reject() to achieve flexible data filtering; 2. Use map() and pluck() to easily convert and extract data; 3. Use countBy() and reduce() to perform data grouping and summary analysis. These methods enable developers to replace traditional array processing logic with more concise and readable code, greatly improving development efficiency.

Using Performance Profilers | Finding Memory Leaks
Memory leak refers to the program not being released correctly after applying for memory, which leads to memory waste and affects performance. Common reasons include unrecycled objects, unbinding listeners, unlimited cache growth, etc. Use performance analysis tools (such as ChromeDevTools, VisualVM, AndroidStudioProfiler) to locate problems: 1. Monitor memory trends and see if it continues to rise; 2. Trigger garbage collection to determine whether the memory cannot be released; 3. Analyze the object retention tree to find the objects and holders that occupy the memory; 4. Compare the heap snapshots to identify the exception newly added objects. Frequently asked questions include Context leaks, long-lifetime objects holding short-lifetime references, and improper cache management. The response method is to use App

Artisan Console Commands | Developer Productivity Tools
Laravel's Artisan command line tool improves development efficiency through code generation, database management, custom commands and debug optimization. 1. Use make:* series commands to quickly generate controller, model, middleware and other files, and support resource controllers and single action controllers. 2. Manage database structure and data through commands such as migrate, db:seed, etc., and supports migration rollback and reset. 3. Use make:command to create a custom Artisan command and combine task scheduling to implement timing operations. 4. Use route:list, config:clear and other commands to debug and perform performance optimization to help troubleshoot configuration and caching problems.
