How to convert date format from dd/mm/yyyy to yyyy-mm-dd using carbon on Laravel

问题

I have small laravel project working on date conversion. I have date string that getting from request on format dd/mm/yyyy. Code and result show as below.

$request->stockupdate ; 
// dd/mm/yyyy (02/05/2019)

Then I try to convert to yyyy-mm-dd using carbon.

$_stockupdate= Carbon::parse($request->stockupdate)->format('Y-m-d'); 

I got parse result as below.

2019/02/05  // Seem it is 2 Feb 2019 not 5 May 2019.

That's wrong, It should be 2019/05/02 instead. Any advise or guidance would be greatly appreciated, Thanks.

You can try this:

Carbon::createFromFormat('d/m/Y', $request->stockupdate)->format('Y-m-d')

You can try this :

 $date = str_replace('/', '-', $request->stockupdate);
 $newDate = date("Y-m-d", strtotime($date));
 OR
 Carbon::createFromFormat('d/m/Y', $request->stockupdate)->format('Y-m-d')
