PHP: strtotime() - consistent results

How venerable is this to the settings of the server?
echo date('F j, Y',strtotime('2015-2-7'));

Open in new window

In some locations, 2015-2-7 could be considered February 7, while in other places it could be considered to be July 2.  What is the most foolproof way to create a timestamp from  a day, month and year?

Use the ISO-8601 standard for all internal representations of date/time values.  Reformat for printing or display.

Test some with Practical Application #7.  You will find that dashes and slashes have different meanings to strtotime().

By convention the format 2015-07-20 (uses dashes) is in UTC format (yyyy-mm-dd)

If you use slashes (2015/20/07) then it is in US format (yyyy/mm/dd)
