"Call to a member function format() on a non-object" when converting date in PHP -

i can not rid of error message:

call member function format() on non-object

so, go on googling , source this stackoverflow question.

i tried similar, failed. code :

$temp = new datetime(); /*error here*/ $data_umat['tanggal_lahir'] = $data_umat['tanggal_lahir']->format('y-m-d'); $data_umat['tanggal_lahir'] = $temp; 

so, did trial & errors, , found out if this:

$data_umat['tanggal_lahir'] = date("y-m-d h:i:s"); 

the date converted, return today's date (which dont want).

i want convert date 10/22/2013 2013-10-22.

you calling method format() on non-object. try this:

$data_umat['tanggal_lahir'] = new datetime('10/22/2013'); $data_umat['tanggal_lahir'] = $data_umat['tanggal_lahir']->format('y-m-d'); 

or one-liner:

$data_umat['tanggal_lahir'] = date_create('10/22/2013')->format('y-m-d');
