How do I display a "Last Modified ..." date?

Philip Olson, php.net

An example is:
<?php
  putenv("PHP_TZ=America/Los_Angeles");
  echo "Last Modified:" . date( "F d, Y. H:i:s a", getlastmod() );
?> 
this prints the files last modification date in the following format:
   Last Modified: May 21, 2000. 14:59:02 am
keep in mind that much of the above is not required, here is a trimmed 
down version:
<?php
  echo date( "F d, Y. H:i:s a", getlastmod() );
?> 
this prints:
  May 21, 2000. 22:59:02 am
the time is different as my server is eight hours ahead of me!
Notes:
timezone: putenv adds the timezone which in this case is PST.
strings: the "F d, Y. H:i:s a" simply dictates the format of your given 
last modification date.  For instance, let's say we did this:
<?php
  echo date( "m/d/Y", getlastmod() );
?>
this prints:
  5/21/2000

To implement, either put this code straight into your footer or 
sometimes it's nice to include it like:
<? include "lastmodified.inc" ?>
with of course lastmodified.inc containing a script simular to the ones 
found above.
