Suppose your file is called index.php... you can use a GET parameter to indicate that you want the next page or the previous. Then use that parameter to decide which file to include.

To use the GET parameter, use this in your link :

<a href="index.php?action=next">next</a>
<a href="index.php?action=back">next</a>

Then in your PHP code you can do this :


if ($_GET['action'] == 'next') include($theRightIncludePathFromArrayForNext);
else include($theRightIncludePathFromArrayForBack);

Sorry the links should be :

<a href="index.php?action=next">next</a>
<a href="index.php?action=back">back</a>

There are many ways to do it. Here is one building on what we have seen so far.
//Links in your home page :
 
<?php if (isset($_GET["p"])) $position = $_GET["p"]; else $position = 0; ?>
<a href="index.php?p=<?php  echo $position; ?>&action=next">next</a>
<a href="index.php?p=<?php  echo $position; ?>&action=back">back</a>
 
//$position, or P specifies your position. Ie which URL you are including from your array. If p =1 then you are using $pages[1].
 
// Your include
 
if (isset($_GET["action"]))
{
    if ($_GET["action"] == "back") 
    { 
        if ($position == 0) $position++; // we can't go back from the first page
        include($pages[$position-1]);
    }
    
    if ($_GET["action"] == "next")
    {
        if ($position == sizeof($pages)) $position--; // we can't go past the last page
        include($pages[$position+1]);
    }
} else include($pages[0]);

A little mistake in my previous code, replace line number 21 with the following :
        if ($position == (sizeof($pages)-1)) $position--; // we can't go past the last page
