问题
I'm starting to read about Carbon and can't seem to figure out how to create a carbon date.
In the docs is says you can;
Carbon::createFromDate($year, $month, $day, $tz); Carbon::createFromTime($hour, $minute, $second, $tz); Carbon::create($year, $month, $day, $hour, $minute, $second, $tz);
But what if I just recieve a date like 2016-01-23? Do I have to strip out each part and feed it to carbon before I can create a carbon date? or maybe I receive time like 11:53:20??
I'm dealing with dynamic dates and time and writing code to separate parts of time or date doesn't feel right.
Any help appreciated.

You can use one of two ways of creating a Carbon instance from that date string:
1. Create a new instance and pass the string to the constructor:
// From a datetime string
$datetime = new Carbon('2016-01-23 11:53:20');
// From a date string
$date = new Carbon('2016-01-23');
// From a time string
$time = new Carbon('11:53:20');
2. Use the createFromFormat method:
// From a datetime string
$datetime = Carbon::createFromFormat('Y-m-d H:i:s', '2016-01-23 11:53:20');
// From a date string
$date = Carbon::createFromFormat('Y-m-d', '2016-01-23');
// From a time string
$time = Carbon::createFromFormat('H:i:s', '11:53:20');
The Carbon class is just extending the PHP DateTime class, which means that you can use all the same methods including the same constructor parameters or the createFromFormat method.
