<?php
// Name: Onefile PHP Script v.2
// Description: One PHP file can host multiple pages with this script.
// There is also an auto-generation of links to previous and next pages

// Usage: index.php?page=1

// Original script: Andy @ http://abyssunderground.co.uk
// This script modified by Stephen Lance

switch ($_GET['page']) {
case 0: defaultPage(); break;
case 1: page1(); break;
case 2: page2(); break;
case 3: page3(); break;
case 4: page4(); break;
case 5: page5(); break;
case 6: page6(); break;
case 7: page7(); break;
case 8: page8(); break;
case 9: page9(); break;
case 10: page10(); break;
case 11: page11(); break;
case 12: page12(); break;
case 13: page13(); break;
case 14: page14(); break;
case 15: page15(); break;
default: defaultPage();
}

function page1() {
echo "<HTML><HEAD><TITLE>Page 1</TITLE></HEAD><BODY>";
echo "Here's the HTML for the page 1.";
echo "</BODY></HTML>";
}

function page2() {
?>
<HTML>
<HEAD>
<TITLE>
</TITLE>
</HEAD>
<BODY>
Here is the HTML. Don't need to worry about PHP here because we're outside
of the PHP tag. Then before this function ends, we're back in PHP.
Any static content might as well be outside the PHP tags.
To go back inside, just do this: (look at the source code)
<PRE>Page ID: <?php echo $_GET['page']; ?></PRE>
<?php
}

function page3() {
header("Content-type: text/plain");
echo "This is just plain text.";
}

<?php 
// Auto Generation of links for $backpages previous pages and $forwpages forward pages
$page = $_GET['page'];

$totalpages = 16; // You have to manually change this with the amount of pages you have
$backpages = 3; // How many links to previous pages you want to see
$forwpages = 6; // How many links to pages ahead you want to see

echo "<HR>";
if(!$page) {$page = 0;}

// Show [Prev]
if ($page > 1) {echo "<a href=\"$_SERVER[PHP_SELF]?page=".($page-1)."\">[Prev]</a>&nbsp;\n";}

// Show links to previous pages - as long as they exist
if ($page >= ($backpages + 1)) {$back = $backpages;} else {$back = ($page - 1);}
for($i = 1; $i <= $back; $i++)
	{echo "<a href=\"$_SERVER[PHP_SELF]?page=".($page + $i - $back - 1)."\">[".($page + $i - $back - 1)."]</a>&nbsp;\n";}

// Show Current Page
echo "[{$page}]&nbsp;\n";

// Show links to pages ahead - as long as they exist
if (($page + $forwpages) <= $totalpages) {$max = $forwpages;} else {$max = ($totalpages - $page);}
for($i = 1; $i <= $max; $i++)
	{echo "<a href=\"$_SERVER[PHP_SELF]?page=".($page + $i)."\">[".($page + $i)."]</a>&nbsp;\n";}

// Shoe [Next]
if ($page <= ($totalpages - 1))
{echo "<a href=\"$_SERVER[PHP_SELF]?page=".($page + 1)."\">[Next]</a>\n";} 
?>

This code allows you to call multiple webpages, all served with by one PHP file.

Version 2 adds a system to generate a specified amount of links to previous pages and pages ahead.
