codeNothing? Web Development from a Beginner

I always hated all the various pagination templates that use full on classes or multiple pages to create a few links. All I needed was a simple function that would do the bare minimum and could easily be manipulated. Here's a little something I created for my own libraries, and hopefully you can find some use of it.

$max_links should be an even number, but the function will add 1 to an odd number. It will also add the page numbers in the form of page=# to the end of your $href variable, so keep that in mind.

 * $href: 		Full link of the current page without the 'page' var
 * $current_page: 	Current page #
 * $total_entries: 	Total number of entries
 * $entries_per_page: 	Maximum entries per page
 * $max_links: 		Maximum links on display
 */
function pageLinks($href, $current_page, $total_entries, $entries_per_page, $max_links=8){
	// Maximum links on display must always start even
	$max_links = ($max_links % 2 == 0) ? $max_links : $max_links+1;

	// Highest page number
	$highest_page = intval(($total_entries/$entries_per_page)+.99);

	// Set the start of the page number
	if ($current_page - ($max_links/2) < 0){
		$page = 0;
	}else if ($current_page + ($max_links/2) > $highest_page-1){
		$page = $highest_page - $max_links;
		if ($page < 0) $page = 0;
	}else{
		$page = $current_page - ($max_links/2);
	}

	// Loop through and set the page links
	for ($i=0; $i<($max_links+1); $i++){
		// Last link to be returned
		if ($i == $max_links || $page == $highest_page-1 || $total_entries <= $entries_per_page){
			// Check to see if page is currently being viewed
			$list .= ($current_page == $page) ? "<b>$page</b>" : "<a href='$href&page=$page'>$page</a>";
			break;
		}
		else{
			// Check to see if page is currently being viewed
			$list .= ($current_page == $page) ? "<b>$page</b>," : "<a href='$href&page=$page'>$page</a>,";
		}
		$page++;
	}
	return $list;
