首先一个分页类,如下(摘自网络)可拷贝直接使用
效果图:
each_disNums = intval($each_disNums);
$this->nums = intval($nums);
if (!$current_page) {
$this->current_page = 1;
} else {
$this->current_page = intval($current_page);
}
$this->sub_pages = intval($sub_pages);
$this->pageNums = ceil($nums / $each_disNums);
$this->subPage_link = $subPage_link;
$this->show_SubPages($subPage_type);
//echo $this->pageNums."--".$this->sub_pages;
}
/*
__destruct析构函数,当类不在使用的时候调用,该函数用来释放资源。
*/
function __destruct() {
unset ($each_disNums);
unset ($nums);
unset ($current_page);
unset ($sub_pages);
unset ($pageNums);
unset ($page_array);
unset ($subPage_link);
unset ($subPage_type);
}
/*
show_SubPages函数用在构造函数里面。而且用来判断显示什么样子的分页
*/
function show_SubPages($subPage_type) {
if ($subPage_type == 1) {
$this->subPageCss1();
}
elseif ($subPage_type == 2) {
$this->subPageCss2();
}
}
/*
用来给建立分页的数组初始化的函数。
*/
function initArray() {
for ($i = 0; $i sub_pages; $i++) {
$this->page_array[$i] = $i;
}
return $this->page_array;
}
/*
construct_num_Page该函数使用来构造显示的条目
即使:[1][2][3][4][5][6][7][8][9][10]
*/
function construct_num_Page() {
if ($this->pageNums sub_pages) {
$current_array = array ();
for ($i = 0; $i pageNums; $i++) {
$current_array[$i] = $i +1;
}
} else {
$current_array = $this->initArray();
if ($this->current_page current_page pageNums && $this->current_page > $this->pageNums - $this->sub_pages + 1) {
for ($i = 0; $i pageNums) - ($this->sub_pages) + 1 + $i;
}
} else {
for ($i = 0; $i current_page - 2 + $i;
}
}
}
return $current_array;
}
/*
构造普通模式的分页
共4523条记录,每页显示10条,当前第1/453页 [首页] [上页] [下页] [尾页]
*/
function subPageCss1() {
$subPageCss1Str = "";
$subPageCss1Str .= "共" . $this->nums . "条记录,";
$subPageCss1Str .= "每页显示" . $this->each_disNums . "条,";
$subPageCss1Str .= "当前第" . $this->current_page . "/" . $this->pageNums . "页 ";

http://blog.csdn.net/tangcheng_ok/article/details/$prewPageUrl = $this->subPage_link . ($this->current_page - 1);

$subPageCss1Str .= "[上一页] ";

/*
构造经典模式的分页

*/
function subPageCss2() {

$subPageCss2Str .= " 首页 ";
$subPageCss2Str .= " 上一页 ";
} else {
$subPageCss2Str .= " 首页 ";
$subPageCss2Str .= " 上一页 ";
}
$a = $this->construct_num_Page();
for ($i = 0; $i current_page) {
$subPageCss2Str .= " " . $s . " ";

} else {
$subPageCss2Str .= " 下一页 ";
$subPageCss2Str .= " 尾页 ";
}
echo $subPageCss2Str;
}
}
?>
在需要分页的php文件中
include_once ("Pagination.php"); //每页显示的条数 $pageSize = 10; //总条目数 $pageTotal = $db->get_var("select count(*) from tb"); //每次显示的页数 $sub_pages = 10; //得到当前是第几页 if (is_array($_GET) && count($_GET) > 0) { if (isset ($_GET["p"])) { //是否存在"id"的参数 $pageCurrent = $_GET["p"]; } } else { $pageCurrent = 1; } $goodses = $db->get_results("SELECT g.id,* FROM tb as g INNER JOIN (select id from tb order by updatetime desc limit " . ($pageCurrent -1) * $pageSize . ",10 )as g1 ON g.id=g1.id");
显示分页数据
