添加路由
代码如下:
Route::get('artiles', 'ArticlesController@index');
创建控制器
代码如下:
php artisan make:controller ArticlesController --plain
修改控制器
<?php namespace App\Http\Controllers; use App\Article; use App\Http\Requests; use App\Http\Controllers\Controller; use Illuminate\Http\Request; class ArticlesController extends Controller { public function index() { $articles = Article::all(); return $articles; } }
可以在浏览器中看到返回的 JSON 结果,cool!
修改控制器,返回视图
public function index() { $articles = Article::all(); return view('articles.index', compact('articles')); }
创建视图
@extends('layout') @section('content') <h1 id="Articles">Articles</h1> @foreach($articles as $article) <article> <h2 id="article-title">{{$article->title}}</h2> <div class="body">{{$article->body}}</div> </article> @endforeach @stop
浏览结果,COOL!!!!
显示单个文章
添加显示详细信息的路由
代码如下:
Route::get('articles/{id}', 'ArticlesController@show');
其中,{id} 是参数,表示要显示的文章的 id,修改控制器:
public function show($id) { $article = Article::find($id); //若果找不到文章 if (is_null($article)) { //生产环境 APP_DEBUG=false abort(404); } return view('articles.show', compact('article')); }
laravel 提供了更加方便的功能,修改控制器:
public function show($id) { $article = Article::findOrFail($id); return view('articles.show', compact('article')); }
It's cool.
新建视图
@extends('layout') @section('content') <h1 id="article-title">{{$article->title}}</h1> <article> {{$article->body}} </article> @stop
在浏览器中尝试访问:/articles/1 /articles/2
修改index视图
@extends('layout') @section('content') <h1 id="Articles">Articles</h1> <hr/> @foreach($articles as $article) <article> <h2> {{--这种方式可以--}} <a href="/articles/{{$article->id}}">{{$article->title}}</a> {{--这种方式更加灵活,不限制路径--}}<br> <a href="{{action('ArticlesController@show', [$article->id])}}">{{$article->title}}</a> {{--还可以使用--}}<br> <a href="{{url('/articles', $article->id)}}">{{$article->title}}</a> </h2> <div class="body">{{$article->body}}</div> </article> @endforeach @stop
以上所述就是本文的全部内容了,希望能够对大家学习Laravel5框架有所帮助。

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

PHP and Python are both high-level programming languages that are widely used in web development, data processing and automation tasks. 1.PHP is often used to build dynamic websites and content management systems, while Python is often used to build web frameworks and data science. 2.PHP uses echo to output content, Python uses print. 3. Both support object-oriented programming, but the syntax and keywords are different. 4. PHP supports weak type conversion, while Python is more stringent. 5. PHP performance optimization includes using OPcache and asynchronous programming, while Python uses cProfile and asynchronous programming.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.
