Laravel Carbon seconds to forHumans

Question

我有一个包含秒的表，我在其中插入在线时间(以秒为单位)，

Carbon::parse($seconds)->forHumans();

不允许我这样做，有一种方法可以解析秒数并将其传输给人类阅读吗？比如1小时还是2周？

Answer 1

这应该会返回您想要的结果：

Carbon::now()->subSeconds($seconds)->diffForHumans();

Answer 2

试试这个：

以人类可读格式表示的碳时间

// $sec will be the value from your seconds table
echo Carbon::now()->addSeconds($sec)->diffForHumans();
// OR
echo Carbon::now()->subSeconds($sec)->diffForHumans();

输出

// if $sec = 5
5 seconds from now

我找到了这个有用的文档Carbon

希望这能对你有所帮助。

1) php artisan make:中间件LastActivityUser

2)将此代码添加到中间件LastActivityUser中

 <?php

namespace App\Http\Middleware;

use Closure;
use Auth;
use Carbon\Carbon;
use Cache;

class LastActivityUser
 {
     /**
     * The authentication factory instance.
     *
     * @var \Illuminate\Contracts\Auth\Factory
     */
     protected $auth;

     /**
     * Create a new middleware instance.
     *
     * @param  \Illuminate\Contracts\Auth\Factory  $auth
     * @return void
     */
     public function __construct(Auth $auth)
     {
         $this->auth = $auth;
     }
     /**
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @return mixed
     */
    public function handle($request, Closure $next)
    {
        if(Auth::check()) {
            $expiresAt = Carbon::now()->addSeconds(10);
            Cache::put('user-is-online-' . Auth::user()->id, true, $expiresAt);
        }
        return $next($request);
    }
}

3)在您的用户模型中添加此函数

public function is_online() {
        return Cache::has('user-is-online-' . $this->id);
    }

4)在(app\Http\Kernel.php)中声明

protected $middlewareGroups = [
   'web' => [

       \App\Http\Middleware\LastActivityUser::class, //Add this Line
   ]

5)在您的模板刀片中

 @if($user->is_online())
   <span>On</span>
 @else 
   <span>Off</span>
 @endif
