Date Quick Reference

[nyo]

Here is my date & time reference file. No need to search internet or check php.net every time I want to display date or time in a different format. I am sure this could be helpful to other newbies like me. Because I have spent some hours for figuring out how date() function works.

<?php

date_default_timezone_set('UTC'); //Available since PHP 5.1

//Display year only: 				2011
echo date('Y');

//Display month and day only: 			May, 15
echo date('F, j');

//Display full date: 				Sunday, May 15th 2011
echo date('l, F dS Y');

//Display date with dots: 			15.05.2011
echo date('d.m.Y');

//Display time in hours and minutes		11:38
echo date('H:i');

//Display date and time				15.05.2011, 11:38
echo date('d.m.Y, H:i');

//Display nth day of the month			15th of May
echo date('jS \o\f F');

//Display time with am/pm			May 15, 2011, 11:38 am
echo date('F j, Y, g:i a');

//Display time EST, PST, etc.			Sun May 15 11:38:58 UTC 2011
echo date("D M j G:i:s T Y");

//Text in date function				It is the 15th day of the month.
echo date('\I\t \i\s \t\h\e jS \d\a\y \o\f \t\h\e \m\o\n\t\h.');

That's actually not such a bad idea. Just to have some regularly used date strings nearby. I might copy your idea and keep some strings as texts to re-use when I need.
