It's not all that difficult, really. It's exactly how it's described
in the manual. Here is some code that runs some samples:

(I must say, though, that most examples can be done a lot easier
without strtotime(), but 'cause these are examples of strtotime()...
well... you know :)

--- PHP Example Code ---
<PRE>
<?php

/* Show a given date (+time) */
print ("Date: \n\t");
print (date ("r", strtotime ("January 31 2000 19:20:15"))."\n\n");

/* Show the current date (+time) */
print ("Now: \n\t");
print (date ("r", strtotime ("now"))."\n\n");

/* Show the date (+time) of tomorrow */
print ("Tomorrow: \n\t");
print (date ("r", strtotime ("tomorrow"))."\n\n");

/* Show the date (+time) of yesterday */
print ("Yesterday: \n\t");
print (date ("r", strtotime ("yesterday"))."\n\n");

/* Show the date (+time) of yesterday, where now is tomorrow. So the
   the output will be today :) */
print ("Yesterday, where 'now' is tomorrow: \n\t");
print (date ("r", strtotime ("yesterday", strtotime("tomorrow")))."\n\n");

/* Show the date (+time) 13 days from december 24th 1998 */
print ("13 days from december 24th 1998: \n\t");
print (date ("r", strtotime ("+13 days", strtotime("December 24 1998")))."\n\n"»

/* Let's say you get some date from the db (or something) and you
 * want to
   add 2 years and 4 months and 23 days. */
print ("Well... just see: \n\t");
$date_from_db = "2001-09-20";
print (date ("r", strtotime ("+2 years +4 months +23 days",
                        mktime(0,0,0,substr($date_from_db, 5, 2),
                                     substr($date_from_db, 8, 2),
                                     substr($date_from_db, 0, 4))))."\n\n");

/* Etc. */
print ("And so on... :)<HR noshade size=\"1\">");

?>
</PRE>
