How to convert MM/DD/YYYY to YYYY-MM-DD?

Question

I have a jquery calendar that sets the input value to MM/DD/YYYY

How would I convert it so that my database column (date) can accept it correctly?

EDIT

Answer 1

I will suggest to use strtotime() function and then date(). By this you can convert any format of date.

$unix_time_stamp = strtotime($mm_dd_yyyy);
$yyyy_mm_dd = date(Y/m/d,$unix_timestamp);
