php framework laravel

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

<&#63;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;
  }

}

Copy after login

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'));
  }

Copy after login

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

Copy after login

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'));
  }

Copy after login

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'));
  }

Copy after login

It's cool.

新建视图

@extends('layout')

@section('content')
  <h1 id="article-title">{{$article->title}}</h1>

  <article>
    {{$article->body}}
  </article>
@stop

Copy after login

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
Copy after login

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。

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

Describe the SOLID principles and how they apply to PHP development. Describe the SOLID principles and how they apply to PHP development. Apr 03, 2025 am 12:04 AM

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.
