php分页问题

php问题，求求帮忙详细得讲解一下这个分页代码
function _PAGEFT($totle, $displaypg = 20, $url = '') {

global $page, $firstcount, $pagenav, $_SERVER;

$GLOBALS["displaypg"] = $displaypg;

if (!$page)
$page = 1;
if (!$url) {
$url = $_SERVER["REQUEST_URI"];
}

//URL分析：
$parse_url = parse_url($url);
$url_query = $parse_url["query"]; //单独取出URL的查询字串
if ($url_query) {
$url_query = ereg_replace("(^|&)page=$page", "", $url_query);
$url = str_replace($parse_url["query"], $url_query, $url);
if ($url_query)
$url .= "&page";
else
$url .= "page";
} else {
$url .= "?page";
}
$lastpg = ceil($totle / $displaypg); //最后页，也是总页数
$page = min($lastpg, $page);
$prepg = $page -1; //上一页
$nextpg = ($page == $lastpg ? 0 : $page +1); //下一页
$firstcount = ($page -1) * $displaypg;
