我知道碳是如何工作的,但我想创造定制的碳功能.carbon有一个函数调用diffForHumans(),我想对该函数进行一些修改并调用该函数diffForHumansCustom().如果我编辑Carbon.php供应商文件,我可以实现我的目标,但修改将会消失composer update.任何建议或代码帮助表示赞赏.
public function diffForHumans(Carbon $other = null, $absolute = false)
{
$isNow = $other === null;
if ($isNow) {
$other = static::now($this->tz);
}
$diffInterval = $this->diff($other);
switch (true) {
case ($diffInterval->y > 0):
$unit = 'year';
$delta = $diffInterval->y;
break;
case ($diffInterval->m > 0):
$unit = 'month';
$delta = $diffInterval->m;
break;
case ($diffInterval->d > 0):
$unit = 'day';
$delta = $diffInterval->d;
if ($delta >= self::DAYS_PER_WEEK) {
$unit = 'week';
$delta = floor($delta / self::DAYS_PER_WEEK);
}
break;
case ($diffInterval->h > 0):
$unit = 'hour';
$delta = $diffInterval->h;
break;
case ($diffInterval->i > 0):
$unit = 'minute';
$delta = $diffInterval->i;
break;
default:
$delta = $diffInterval->s;
$unit = 'second';
break;
}
if ($delta == 0) {
$delta = 1;
}
$txt = $delta . ' ' . $unit;
$txt .= $delta == 1 ? '' : 's';
if ($absolute) {
return $txt;
}
$isFuture = $diffInterval->invert === 1;
if ($isNow) {
if ($isFuture) {
return $txt . ' from now';
}
return $txt . ' ago';
}
if ($isFuture) {
return $txt . ' after';
}

if ($delta == 0) {

}
$txt = $delta . ' ' . $unit;
$txt .= $delta == 1 ? '' : 's';
if($unit == 'second' && $delta<=59) {
return 'Just now';
}
// Greater than 3 days
// [xx] [Month] [year, only displays if not current year'] at [time in 24 clock].
if(($unit == 'day' && $delta > 3) || ($unit == 'week') || ($unit == 'month') || ($unit == 'year')) {
$timestamp = $this->getTimestamp();
$curYear = date('Y');

您可以扩展碳类,然后使用您的子类代替碳,或者只需diffForHumansCustom()使用方法创建特征并在您的类中使用它
扩展碳\碳:
<?php
namespace App\Http\Controllers\Helpers;
use Carbon\Carbon;
class CarbonCopy extends Carbon {
public function diffForHumansCustom(Carbon $other = null, $absolute = false) {
// YOUR UNIQUE IMPLEMENTATION, CODE & LOGIC...
}
}
使用Trait代替:
<?php
namespace App\Http\Controllers\Helpers;
use Carbon\Carbon;
trait CarbonT {
public function diffForHumansCustom(Carbon $other = null, $absolute = false) {
// YOUR UNIQUE IMPLEMENTATION, CODE & LOGIC...
}
}
控制器内部的使用:作为特征
<?php
namespace App\Http\Controllers;
use App\Http\Controllers\Helpers\CarbonT;
use Carbon\Carbon;
use Illuminate\Http\Request;
use App\Http\Requests;
use App\User;
class TestController extends Controller {
use CarbonT;
public function carbonRelatedOperation(){
$cbnDate = Carbon::createFromFormat("Y-m-d H:i:s", "2016-05-02 11:11:11");
$customDiff = $this->diffForHumansCustom($cbnDate);
dd( $customDiff );
}
}
控制器内部的使用:作为碳的子类
<?php
namespace App\Http\Controllers;
use App\Http\Controllers\Helpers\CarbonCopy;
use Carbon\Carbon;
use Illuminate\Http\Request;
use App\Http\Requests;
use App\User;
class TestController extends Controller {
public function carbonRelatedOperation(){
$cbnDate = Carbon::createFromFormat("Y-m-d H:i:s", "2016-05-02 11:11:11");
$cbCopy = new CarbonCopy();
dd( $cbCopy->diffForHumansCustom($cbnDate) );
}
}
对于 2019 年来到这里的任何人，我发现添加Carbon::macro函数之类的东西的更简洁的解决方案是使用 LaravelServiceProvider
1）创建您的服务提供者 php artisan make:provider CarbonServiceProvider
碳服务提供者
<?php
namespace App\Providers;
use Carbon\Carbon;
use Illuminate\Support\ServiceProvider;
class CarbonServiceProvider extends ServiceProvider
{
/**
* Register services.
*/
public function register()
{
}
/**
* Bootstrap services.
*/
public function boot()
{
Carbon::macro('easterDate', function ($year) {
return Carbon::createMidnightDate($year, 3, 21)->addDays(easter_days($year));
});
}
}
2) 注册您的服务提供商 config/app.php
应用程序/配置
<?php
return [
'providers' => [
...
/*
* Application Service Providers...
*/
App\Providers\AppServiceProvider::class,
App\Providers\AuthServiceProvider::class,
App\Providers\BroadcastServiceProvider::class,
App\Providers\EventServiceProvider::class,
App\Providers\RouteServiceProvider::class,
App\Providers\DatabaseServiceProvider::class,
App\Providers\CarbonServiceProvider::class,
...
],
];
3) 您现在可以从应用程序的任何位置访问您的宏。
示例控制器
<?php
namespace App\Http\Controllers;
use Carbon\Carbon;
use Illuminate\Http\Request;
use App\Http\Controllers\Controller;
class ExampleController extends Controller
{
/**
* Show the form for creating a new resource.
*
* @return \Illuminate\Http\Response
*/
public function index(Request $request)
{
dd(Carbon::easterDate(2015));
}
}
在示例中，这应该返回
Carbon @1428192000 {#2663 ?
date: 2015-04-05 00:00:00.0 UTC (+00:00)
}
享受！
