I hope everyone has a great holiday.

I have a date in this format: 23-12-2011 and would like to cancel it in the US format 2011-12-23 .

Does anyone know how I can do this in PHP? Is there any function to split the lines?

Answer 1

 date("Ymd", strtotime("23-12-2011")) 

Answer 2

 $date = DateTime::createFromFormat('dm-Y', '23-12-2011'); echo $date->format('Ym-d'); 

Voila. Check datetime class PHP5s
