  2. Find the MySQL connection settings for your database.
  3. Add the following configuration options to the MySQL connection settings:
1
2
'charset' => 'utf8mb4',
'collation' => 'utf8mb4_unicode_ci',


  1. Save the changes to the configuration file.
  2. Run the following command to clear the configuration cache:

How to format dates and times when retrieving data from MySQL in Laravel?

When retrieving data from MySQL in Laravel, you can format dates and times using Carbon, a simple PHP API extension for DateTime. Here's how you can format dates and times in Laravel:

  1. Create a model for your database table:
1
php artisan make:model Post


  1. Define the date columns in your model and set them as Carbon instances:
1
2
3
4
5
6
7
8
namespace App;

use Illuminate\Database\Eloquent\Model;

class Post extends Model
{
    protected $dates = ['created_at', 'updated_at'];
}


  1. In your controller, retrieve the data from the database and format the dates using Carbon:
1
2
3
4
5
6
7
8
$posts = Post::all();

foreach($posts as $post) {
    $formattedCreatedAt = $post->created_at->format('Y-m-d H:i:s');
    $formattedUpdatedAt = $post->updated_at->format('Y-m-d H:i:s');
    
    // Use the formatted dates as needed
}


  1. You can also define an accessor in your model to format dates before they are retrieved:
1
2
3
4
public function getCreatedAtAttribute($value)
{
    return Carbon::parse($value)->format('Y-m-d H:i:s');
}


With this approach, whenever you access the created_at attribute of a Post instance, it will be formatted according to the specified format.


By using Carbon and defining date columns in your model, you can easily format dates and times when retrieving data from MySQL in Laravel.
