Using Carbon to return a human readable datetime difference

问题

I'm using Laravel 4 to create my project.

I am currently building the comments section and I want to display how long ago the post was created, kind of like Facebook's '10 mins ago' & '2 weeks ago' etc.

I have done a little bit of research and found that a package called Carbon can do this.

After reading the Laravel doc's, it says:

By default, Eloquent will convert the created_at, updated_at, and deleted_at columns to instances of Carbon, which provides an assortment of helpful methods, and extends the native PHP DateTime class.

But when I return a date column that I have created, it doesn't display it like on Facebook.

The code that I'm using is:

return array('time');

Has any body used this Carbon package that could give me a hand in doing what I need, I'm quite confused.

回答1:

If you read the Carbon docs to get what you want you call the diffForHumans() method.

<?php echo \Carbon\Carbon::createFromTimeStamp(strtotime($comment->created_at))->diffForHumans() ?>

By default, Eloquent will convert the created_at, updated_at, and deleted_at columns to instances of Carbon. So, your code should be just like this:

$comment->created_at->diffForHumans();

It's very cool. It'll produce string like 2 minutes ago or 1 day ago. Plurar or singular, seconds, minutes, hours, days, weeks, or years, it runs automatically. I've tested it on Laravel version 4.1.24.

For any version of Laravel

$message->updated_at->diffForHumans();

use this code for time ago :

public function time_elapsed_string($datetime, $full = false) {
$now = new DateTime;
$ago = new DateTime($datetime);
$diff = $now->diff($ago);

$diff->w = floor($diff->d / 7);
$diff->d -= $diff->w * 7;

$string = array(
     'y' => 'year',
     'm' => 'month',
     'w' => 'week',
     'd' => 'day',
     'h' => 'hour',
     'i' => 'minute',
     's' => 'second',
 );
 foreach ($string as $k => &$v) {
     if ($diff->$k) {
         $v = $diff->$k . ' ' . $v . ($diff->$k > 1 ? 's' : '');
     } else {
         unset($string[$k]);
     }
 }

 if (!$full) $string = array_slice($string, 0, 1);
 return $string ? implode(', ', $string) . ' ago' : 'just now';

}

Carbon::parse($p->created_at)->diffForHumans();
