php仿discuz分页效果代码

　　复制代码 代码如下:
/**
* 显示样式2
*/
function multi($mpurl,$page = 10) {

$multipage = ;
$mpurl .= strpos($mpurl, ?) ? & : ?;
$realpages = 1;
if($this->infocount > $this->items) {
$offset = 2;

$realpages = @ceil($this->infocount / $this->items);
$pages = $this->maxpages && $this->maxpages < $realpages ? $this->maxpages : $realpages;

if($page > $pages) {
$from = 1;
$to = $pages;
} else {
$from = $this->pageno - $offset;
$to = $from + $page - 1;
if($from < 1) {
$to = $this->pageno + 1 - $from;
$from = 1;
if($to - $from < $page) {
$to = $page;
}
} elseif($to > $pages) {
$from = $pages - $page + 1;
$to = $pages;
}
}

$multipage = ($this->pageno - $offset > 1 && $pages > $page ? <a href=.$mpurl.page=1 class=first>1 ...</a> : ).
($this->pageno > 1 ? <a href=.$mpurl.page=.($this->pageno - 1). class=p_redirect><<</a> : );
for($i = $from; $i <= $to; $i++) {
$multipage .= $i == $this->pageno ? <a class=p_curpage><strong>.$i.</strong></a> :<a href=.$mpurl.page=.$i. class=p_num>.$i.</a>;
}

$multipage .= ($this->pageno < $pages ? <a href=.$mpurl.page=.($this->pageno + 1). class=p_redirect>>></a> : ).
($to < $pages ? <a href=.$mpurl.page=.$pages. class=last>... .$realpages.</a> : ).
($pages > $page ? <kbd><input type=text name=custompage size=3 onkeydown=if(event.keyCode==13) {window.location=\.$mpurl.page=\+this.value; return false;} /></kbd> : );

$multipage = $multipage ? <div class=p_bar><a class=p_total> .$this->infocount. </a><a class=p_pages> .$this->pageno./.$pages. </a>.$multipage.</div> : ;
}
return $multipage;
}

这是效果:
