以正确的格式在laravel中显示日期时间

Question

I have a blog created with Laravel 5.5, In PostController and in Create function i have specified the time format for "Published_at" cloumn to 24 format, and it's inserted correctly into database with the right format

Nov 30, 2017 | 17:11:19

But when i try to display the time in post page i got this format

30, 11, 2017 | 1:51:29 pm

I don't know why, i have tried to use

date('M j,Y | H:i:s' ,strtotime($post->published_at)) 

solution but i got wrong date and time

I hope the problem clearly described. This is the code used to validate the date format in store function

'published_at' => [
            'required',
            'regex:/^[\d]{2},\s[\d]{2},\s[\d]{4}\s\|\s[\d]{2}:[\d]{2}:[\d]{2}$/',
        ],

And in create page the date display correctly

<input type="text" class="form-control" id="published_at" name="published_at" value="{{ old('published_at', date('M j, Y | G:i:s')) }}" autofocus>

But in Other pages when i use {{ $post->published_at }} or {{ $post->created_at }}... the time display in 12 format

更新的代码

echo DateTime::createFromFormat('d, m, Y \| h:i:s A', $post->published_at)->format('M j,Y | H:i:s');
