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

assign the date values to variable $d

$dob denotes the date which you wish to convert

$d= date('Y-m-d',strtotime ($dob) );
