<h1>Make your web page more dynamic</h1>
This page demonstrates some easy little scripts in PHP.
See <a href=http://www.wellho.net/mouth/624_.html>a
short description of how they work</a> which I've written on
<a href=http://www.wellho.net/horse/>The Horse's Mouth</a>.
<br><br>
1. to show the current month and year on your page:<br>
It is now <?= date ("F Y") ?>
<br><br>
2. to include an image that steps through a cycle, showing
each image in turn for 70 minutes:<center>
<?php $imagelist = array("klake","chill","swood");
#%% Some easy things to do with PHP
$textlist = array("Killingworth Lake","Crickely Hill",
"Swainswick Wood");
$picnumber = floor(time()/60/70)%count($imagelist);
echo ("<img src=$imagelist[$picnumber].jpg><br>");
echo ("<b>$textlist[$picnumber]</b>"); ?>
</center><br>
3. To include the content of a text file (that can contain
a message of the day that you can easily update):<br>
<?php include("../../include/demo.txt"); ?>
<br><br>
4. To include the page's own URL:<br>
This page is at
http://<?php
echo ($_SERVER[SERVER_NAME]);
echo ($_SERVER[REQUEST_URI]); ?>
<br><br>
5. To display the source code of a PHP page (be very careful
of this one - I'm using it to show you how this page works
but it does reveal your tricks - and any security holes in
them - to your site visitors:<br>
<?php /* highlight_file($_SERVER[SCRIPT_FILENAME]); */ ?>
<?php /* PREVIOUS LINE works for most people - we wrap it as
follows since our demo pages are wrapped in a protective blanket */ ?>
<?php highlight_file("$_SERVER[DOCUMENT_ROOT]$_SERVER[REDIRECT_URL]"); ?>
