How to implement a tagging system in Laravel?

Using the spatie/laravel-tags package is the recommended method for implementing the tag system in Laravel. It supports polymorphic relationships, translation and custom tag types; 2. Manual implementation can be completed by creating tags and taggables tables and using morphToMany relationships, suitable for scenarios that require full control; 3. In either way, unique constraints, indexing and cache should be used to optimize performance, and unless there are special customization requirements, the final choice depends on the project complexity and flexibility requirements.

How to work with Blade templating engine in Laravel?

To effectively use Laravel's Blade template engine, you must first master its syntax and structure. Blade compiles templates into PHP code through concise syntax and caches them to improve performance. 1. When creating a Blade view, save it in the resources/views directory and use the .blade.php extension to output variables (auto escape) through {{$variable}}, or use {!!$value!!} to output unescaped content (user input needs to be handled with caution). 2. Use the Blade control structure to implement logic: @if, @elseif, @else, @endif for conditional judgment; @foreach, @for, @endforel
