归类用法

p.p1 { margin: 0.0px 0.0px 0.0px 0.0px; font: 12.0px ".PingFang SC"; color: #454545 }
p.p2 { margin: 0.0px 0.0px 0.0px 0.0px; font: 12.0px "Helvetica Neue"; color: #454545 }
p.p3 { margin: 0.0px 0.0px 0.0px 0.0px; font: 12.0px "Helvetica Neue"; color: #454545; min-height: 14.0px }
p.p4 { margin: 0.0px 0.0px 2.0px 0.0px; font: 14.0px ".PingFang SC"; color: #454545 }
span.s1 { font: 12.0px ".PingFang SC" }
span.s2 { font: 12.0px "Helvetica Neue" }
span.s3 { font: 14.0px "Helvetica Neue" }

查

$links = Links::all();

$configs = Options::all(array(‘id‘, ‘option_name‘, ‘option_value‘));

$category = Categorys::where(‘category_flag‘, $flag)->first();

$post = Posts::where(‘flag‘, $flag)->first();

$posts = Posts::OfType(‘post‘)->orderBy(‘id‘, ‘desc‘)->take(15)->get();

$posts = $category->posts()->paginate(15);//关系，这个分类的文章15个，$this->belongsTo(‘Categorys::class’) ,$this->belongsToMany(‘Tags::class’);

$posts = Posts::orderBy(‘id‘, ‘desc‘)->paginate(15);

Posts::increment(‘views‘, 1);

$post->categories;

$post->tags;

$post->user;

$categorys = Categorys::firstOrCreate([‘category_name‘ => $category]);

特殊函数

$key = hash(‘sha256‘, $flag);

Cache

$post = cache($key);

cache([$key => $post], $this->expiresAt);

Cache::has(‘rss-feed‘)

Cache::add(‘rss-feed‘, $rss, $expiresAt);

return Cache::get(‘rss-feed‘);

}

时间函数

{{$post->created_at->format(‘c‘)}

$this->expiresAt = Carbon::now()->addMinutes(1440);

$expiresAt = Carbon::createFromTimestamp(strtotime($options->updated_at))->addMinutes(10);//获取距离当前时间函数

$ts = Carbon::yesterday()->timestamp;

//人性化显示时间

echo Carbon::createFromTimestamp($ts)->diffForHumans();

上面的打印结果是1天前

Carbon::createFromTimestamp(strtotime($date))->addDays(30);

carbon->toDateString() <= date(‘Y-m-d‘)

跳转函数

<a href="{{ route(‘tags‘,[$tag->tags_flag]) }}"

->url(url(‘/‘)) //里面放的是路由值

->url(url(‘/post/‘ . $post->flag))

$data[‘link‘] = route(‘posts‘, [$post->wp_slug]);//名字

响应

return response($rss)->header(‘Content-type‘, ‘text/xml; charset=UTF-8‘);

return response($map)->header(‘Content-type‘, ‘text/xml‘);

return response()->json($lists);

2  build做方法名称不错

buildRssData

public function authenticate($email, $password)//认证
