想修改PHPCMS分页的URL有好人吗?该怎么解决

function pages($num, $curr_page, $perpage = 20, $urlrule = '', $array = array(), $catid = 0){ global $PHPCMS; if($PHPCMS['pagemode'] && $num > $perpage) { $url = load('url.class.php'); $multipage = ''; if($num > $perpage) { $page = 11; $offset = 4; $pages = ceil($num / $perpage); $from = $curr_page - $offset; $to = $curr_page + $offset; $more = 0; if($page >= $pages) {$from = 2;$to = $pages-1; } else {if($from = $pages){ $from = $pages-($page-2); $to = $pages-1;}$more = 1; } if($urlrule == '') $urlrule = url_par('page={$page}'); $multipage .= '总数：'.$num.' '; if($curr_page>0) {$multipage .= $catid ? 'category($catid, $curr_page-1, 1, 1).'">上一页' : '上一页';if($curr_page==1){ $multipage .= '1 ';}elseif($curr_page>6 && $more){ $multipage .= $catid ? 'category($catid, 1, 1, 1).'">1..' : '1..';}else{ $multipage .= $catid ? 'category($catid, 1, 1, 1).'">1' : '1 ';} } for($i = $from; $i '.$i.' ' : ''.$i.' ';}else{ $multipage .= ' '.$i.' ';} } if($curr_page<$pages) {if($curr_page'.$pages.' category($catid, $curr_page+1, 1).'">下一页' : '..'.$pages.' 下一页';}else{ $multipage .= $catid ? 'category($catid, $pages, 1, 1).'">'.$pages.' category($catid, $curr_page+1, 1, 1).'">下一页' : ''.$pages.' 下一页';} } elseif($curr_page==$pages) {$multipage .= ' '.$pages.'下一页'; } } return $multipage; } else { $total = $num; $page = $curr_page; if($num category($catid, 1, 1, 1); $prepage = $url->category($catid, $prepage, 1, 1); $nextpage = $url->category($catid, $nextpage, 1, 1); $lastpage = $url->category($catid, $pages, 1, 1); $urlpre = $url->category($catid, '', 1, 1); } else { $firstpage = pageurl($urlrule, 1, $array); $prepage = pageurl($urlrule, $prepage, $array); $nextpage = pageurl($urlrule, $nextpage, $array); $lastpage = pageurl($urlrule, $pages, $array); $urlpre = pageurl($urlrule, '', $array); } $data = str_replace('"', '\"', $PHPCMS['pageshtml']); eval("\$url = \"$data\";"); return $url; }}
