Simple, just loop through the pages and appending a new link for each
page you have.

Something like:
/*
* start code. UNTESTED!
*/
$links = 'Page: ';
for ($x = 1; $x <= $pageCount; $x++){ // each page in $pageCount

if ($x == $_GET['page']){
$links .= $x; // current page, no link.
} else {
$links .= '<a href="foo.php?page=' . $x . '">';
$links .= $x . '</a>';
}

// add sep char
if ($x < $pageCount){
$links .= ' | ';
}
}
/*
* end code
*/

Now the string $links contains a link for each page represented by
$pageCount. Just echo the $link var.

You probably want to add some code to enforce a $MAX_LINKS option, so
that in the case of a very long article you don't end up printing a
whole screenful of links.
