Verify an expiration date

Sometimes it's necessary to verify the expiration date of something, for example a token.

Next, I share the function that Laravel uses to verify if your password reset token has expired.

On the other hand, I was unaware of the existence of the isPast function of Carbon, so which, it's necessary to reread his documentation.

The tokenExpired($created_at, $token) function can be found in the vendor folder of the DatabaseTokenRepository class in the namespace Illuminate\Auth\Passwords;. It executes the following:

return Carbon::parse($createdAt)->addSeconds($this->expires)->isPast();

So, for example:

$created_at = DB::table('password_resets')->first()['created_at'];
// => 2018-01-08 09:59:26

// Carbon::now();
// => 2018-01-08 11:03:05

// => true (with an expiration date of 1 hour)
