Question

I was using CI as my framework. How can I set a CONSTANT date format so that I don’t need to change and search for date("y-m-d") in all file?

Answer 1

Put this is a common header file:

define('my_date_format', 'y-m-d');

To use the constant:

// remember to include the header file first
date(my_date_format);

To format 2010-11-10 10:12:11 to date(m.d.y):

$myDate = new DateTime('2010-11-10 10:12:11');
$myDate->format('m.d.y');
