1. Blade视图文件使用.blade.php文件扩展并存放在resources/views目录下。
2. routes.php

Route::get('/child', function () {
    $records=['a','b','c'];
    return view('layouts/child',[
    'firstStr'=>'hello child h3 firstStr',
    'name'=>'name hello',
    'records'=>$records
]);
});

master.blade.php

<h3>@yield('firstStr')</h3>
<h3>{{ time() }}</h3>
<h3>{{ isset($name) ? $name : 'Default' }}</h3>
<h3>
            @if (count($records) === 1)
                I have one record!
            @elseif (count($records) > 1)
                I have multiple records!
            @else
                I don't have any records!
            @endif
</h3>
<div class="container">
            @yield('content')
 </div>

child.blade.php

@extends('layouts.master')
@section('firstStr')
 {{ $firstStr }}
@endsection
@section('content')
    <p>This is my body content.</p>
    <h3>
        @inject('metrics', 'App\Services\Hello')
        <div>
        Monthly Revenue: {{ $metrics->haha() }}.
    </div>
    </h3>
@endsection

App/Services/Hello.php

<?php
namespace App\Services;
class Hello
{  
    public function haha()
    {
       return "Services Hello haha";
    }
}

3. 循环

//
@for ($i = 0; $i < 10; $i++)
    The current value is {{ $i }}
@endfor
//
@foreach ($users as $user)
    <p>This is user {{ $user->id }}</p>
@endforeach
//
@forelse ($users as $user)
    <li>{{ $user->name }}</li>
@empty
    <p>No users</p>
@endforelse
//
@while (true)
    <p>I'm looping forever.</p>
@endwhile
