请问用php怎样完成数字分页？（详细代码）

可以有个PAGE变量，然后下面的上一页6 7 8 9 10 11 12 13 14 15 下一页这一段根据PAGE变量来显示，然后点击就通过GET传过去撒

用偶的吧，还可以的。你试试。今天刚修改过。

可以试试我写的,根据ADODB里的分页类重改写的,必须与ADODB同时使用:

我的，你看看合要求吗
http://club.phpe.net/index.php?act=ST&f=6&t=6028&hl=扶虺&s=

最简单的：
$num 记录数
$perpage 一页多少条
$curr_page 当前页
$mpurl 链接地址function multi($num, $perpage, $curr_page, $mpurl) {
$multipage = '';
if($num > $perpage) {
$page = 10;
$offset = 2; $pages = ceil($num / $perpage);
$from = $curr_page - $offset;
$to = $curr_page + $page - $offset - 1;
if($page > $pages) {
$from = 1;
$to = $pages;
} else {
if($from < 1) {
$to = $curr_page + 1 - $from;
$from = 1;
if(($to - $from) < $page && ($to - $from) < $pages) {
$to = $page;
}
} elseif($to > $pages) {
$from = $curr_page - $pages + $to;
$to = $pages;
if(($to - $from) < $page && ($to - $from) < $pages) {
$from = $pages - $page + 1;
}
}
}
$multipage .= '<a href="'.$mpurl.'&page=1"><<</a>  ';
for($i = $from; $i <= $to; $i++) {
if($i != $curr_page) {
$multipage .= '<a href="'.$mpurl.'&page='.$i.'">['.$i.']</a> ';
} else {
$multipage .= '['.$i.'] ';
}
}
$multipage .= $pages > $page ? " ... <a href=\"$mpurl&page=$pages\"> [$pages] >></a>" : " <a href=\"$mpurl&page=$pages\">>></a>";

return $multipage;
