又一款php分页类代码

class multipage {

var $total;
var $perpage;
var $pages;
var $maxpage;
var $offset = 9;
var $curr_page;

function init($total, $perpage, $maxpage) { //初始化页数
$this->total;
$this->perpage;
$this->maxpage;
$this->offset = 9;
}

function getpagelist() {//获取分页列表
$result_pages = "";
$this->pages = ceil($this->total / $this->perpage);

if ($this->pages > $this->maxpage) {
$from = $this->curr_page - $this->offset;
if ($from < 1) {
$from = 1;
}
$to = $from + $this->maxpage - 1;
if ($to > $this->pages) {
$to = $this->pages;
if (($to - $from) < $this->maxpage) {
$from = $from - 1;
}
}
} else {
$from = 1;
$to = $this->pages;
}

$p = 0;
for($i = $from; $i <= $to; $i++) {
$result_pages[$p] = $i;
$p++;
}

return $result_pages;
}

function getfirst() { //获取第一页
if ($this->curr_page > 1 && $this->pages > 1) {
return 1;
} else {
return "";
}
}

function getlast() { //取末页
if ($this->pages > 1 && $this->curr_page < $this->pages) {
return $this->pages;
} else {
return "";
}
}

function getprev() {//上一页
$prevpage = $this->curr_page - 1;
if ($prevpage > 0) {
return $prevpage;
} else {
$prevpage = "";
return $prevpage;
}
}

function getnext() {//下一页
$nextpage = $this->curr_page + 1;
if ($nextpage <= $this->pages) {
return $nextpage;
} else {
$nextpage = "";
return $nextpage;
}
}

function gettotal() {//共多少页
if ($this->pages > 0) {
return $this->pages;
} else {
return 1;
}
}

}

//分页类的使用方法

$page = new multipage();
$page->gettotal(); //总页娄
$page->getnext();//下一页
