如何在laravel上获得含碳量的生日（年，月，日）？

I want to convert a birthdate to format year, month, day with carbon on laravel 5.4

according the carbon's documentation the method to get an age on blade is this

Carbon\Carbon::parse($bday)->age

but the result is '0' and i want this

$bday =  '2017-10-01' =  0 year 1 month 4 days

Thank you and sorry my English.

Carbon's age returns just the number of years in a person's age, as you have seen.

In your model, you could set up a getAge method that will return the age in years, months and days:

public function getAge(){
    return $this->birthdate->diff(Carbon::now())
         ->format('%y years, %m months and %d days');
}

You can call your model in the view as $user->getAge()
