在这里和大家分享一个非常好用的 Zend Framework 分页类
具体效果可见本站的分页效果, CSS样式可根据个人设计感进行更变。
这里我会举例演示如何使用该类, 如下:
IndexController.php, 在 Action 中写入如下代码:
复制代码 代码如下:
protected $_curPage = 1; //默认第一页
const PERPAGENUM = 4; //每页显示条目数
public function indexAction()
{
// $this->_blogModel 已实例化 blog Model
// $rows -> 获得到所展示数据的总条目数
$rows = $this->_blogModel->getTotalRows();
if($pageNum = $this->getRequest()->getParam('page')) {
//如果有值传入,覆盖初始的第一页
$this->_curPage = $pageNum;
}
//把数据表中的数据传到前端
$this->view->blogInfo = $this->_blogModel->getBlogInfo(
self::PERPAGENUM, ($this->_curPage-1)*self::PERPAGENUM
);
//实例化分页类,并传到前端
$this->view->pagebar = $this->displayPageBar($rows);
}
private function displayPageBar($totalRows)
{
$Pager = new Zend_Pagination($totalRows,self::PERPAGENUM);
return $Pager->getNavigation();
}
models/Blog.php,写入如下代码:
复制代码 代码如下:
public function getBlogInfo($perPageNum = NULL, $limit = NULL)
{
return $this->fetchAll('1 = 1', 'blog_id desc', $perPageNum, $limit)
->toArray();
}
public function getTotalRows($where = '1=1')
{
return $this->fetchAll($where)->count();
}
index.phtml, 写入如下代码:
复制代码 代码如下:
pagebar; ?>
到这里,就可以看见效果了, 如想追求更好的页面效果, 请根据个人喜好修改分页类,这里就不作详细示例
复制代码 代码如下:
class Zend_Pagination
{
private $_navigationItemCount = 6; //导航栏显示导航总页数
private $_pageSize = null; //每页项目数
private $_align = "right"; //导航栏显示位置
private $_itemCount = null; //总项目数
private $_pageCount = null; //总页数
private $_currentPage = null; //当前页
private $_front = null; //前端控制器
private $_PageParaName = "page"; //页面参数名称
private $_firstPageString = "|
private $_nextPageString = ">>"; //导航栏中前一页显示的字符
private $_previousPageString = "
private $_lastPageString = ">>|"; //导航栏中最后一页显示的字符
private $_splitString = " | "; //页数字间的间隔符
public function __construct($itemCount, $pageSize)
{
if (!is_numeric($itemCount) || (!is_numeric($pageSize))) {
throw new Exception("Pagination Error:not Number");
}
$this->_itemCount = $itemCount;
$this->_pageSize = $pageSize;
$this->_front = Zend_Controller_Front::getInstance();
$this->_pageCount = ceil($itemCount/$pageSize); //总页数
$page = $this->_front->getRequest()->getParam($this->_PageParaName);
if (empty($page) || (!is_numeric($page))) {
//为空或不是数字,设置当前页为1
$this->_currentPage = 1;
} else {
if ($page
$page = 1;
}
if ($page > $this->_pageCount) {
$page = $this->_pageCount;
}
$this->_currentPage = $page;
}
}
public function getCurrentPage()
{
return $this->_currentPage;
}
public function getNavigation()
{
$navigation = '
//当前页处于第几栏分页
$pageCote = ceil($this->_currentPage / ($this->_navigationItemCount - 1)) - 1;
//总分页栏
$pageCoteCount = ceil($this->_pageCount / ($this->_navigationItemCount - 1));
//分页栏中起始页
$pageStart = $pageCote * ($this->_navigationItemCount -1) + 1;
//分页栏中终止页
$pageEnd = $pageStart + $this->_navigationItemCount - 1;
if($this->_pageCount $pageEnd = $this->_pageCount;
}
$navigation .= "总共: {$this->_itemCount} 条 共 {$this->_pageCount} 页\n ";
if($pageCote > 0) { //首页导航
$navigation .= '$this->_firstPageString ";
}
if($this->_currentPage != 1) { //上一页导航
$navigation .= '$this->_previousPageString ";
}else{
$navigation .= $this->_previousPageString . ' ';
}
while ($pageStart {
if ($pageStart == $this->_currentPage) {
$navigation .= "$pageStart" . $this->_splitString;
} else {
$navigation .= '$pageStart"
. $this->_splitString;
}
$pageStart++;
}
if($this->_currentPage != $this->_pageCount) { //下一页导航
$navigation .= ' $this->_nextPageString ";
}else{
$navigation .= $this->_nextPageString;
}
if ($pageCote $navigation .= '$this->_lastPageString ";
}
$navigation .= ' 到 ';
$navigation .= " 页
return $navigation;
}
public function getNavigationItemCount()
{
return $this->_navigationItemCount;
}
public function setNavigationItemCoun($navigationCount)
{
if(is_numeric($navigationCount)) {
$this->_navigationItemCount = $navigationCount;
}
}
public function setFirstPageString($firstPageString)
{
$this->_firstPageString = $firstPageString;
}
public function setPreviousPageString($previousPageString)
{
$this->_previousPageString = $previousPageString;
}
public function setNextPageString($nextPageString)
{
$this->_nextPageString = $nextPageString;
}
public function setLastPageString($lastPageString)
{
$this->_lastPageString = $lastPageString;
}
public function setAlign($align)
{
$align = strtolower($align);
if ($align == "center") {
$this->_align = "center";
} elseif ($align == "right") {
$this->_align = "right";
} else {
$this->_align = "left";
}
}
public function setPageParamName($pageParamName)
{
$this->_PageParaName = $pageParamName;
}
public function getPageParamName()
{
return $this->_PageParaName;
}
private function createHref($targetPage = null)
{
$params = $this->_front->getRequest()->getParams();
$module = $params["module"];
$controller = $params["controller"];
$action = $params["action"];
$targetUrl = $this->_front->getBaseUrl()
. "/$module/$controller/$action";
foreach ($params as $key => $value)
{
if($key != "controller" && $key != "module"
&& $key != "action" && $key != $this->_PageParaName) {
$targetUrl .= "/$key/$value";
}
}
if (isset($targetPage)) { //指定目标页
$targetUrl .= "/$this->_PageParaName/$targetPage";
} else {
$targetUrl .= "/$this->_PageParaName/";
}
return $targetUrl;
}
}
这里再简单回顾下 Mysql 中的 limit offset
假设数据库表 blog 存在 13 条数据。
语句1:select * from blog limit 9, 4
语句2:select * from blog limit 4 offset 9
//语句1和2均返回表 blog 的第 10、11、12、13 行
//语句1中的 9 表示从表的第十行开始, 返回 4 行
//语句2中的 4 表示返回 4 行,offset 9 表示从表的第十行开始
如下语句显示分页效果:
语句3:select * from blog limit ($this->_curPage - 1)* self::PERPAGENUM, self::PERPAGENUM;
语句4:select * from blog limit self::PERPAGENUM offset ($this->_curPage - 1) * self::PERPAGENUM;

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
