php实现google样式的分页
废话不多说,直接看代码吧 Pager.class.php 代码如下 class Pager{ /** *int总页数 **/ protected $pageTotal ; /** **/ protected $previous ; /** **/ protected $next ; /** *int中间页起始序号 **/ protected $startPage ; /** *int中间页终止序号 **/ pr
废话不多说,直接看代码吧
Pager.class.php 代码如下
- class Pager {
- /**
- *int 总页数
- * */
- protected $pageTotal;
- /**
- * */
- protected $previous;
- /**
- * */
- protected $next;
- /**
- *int 中间页起始序号
- * */
- protected $startPage;
- /**
- *int 中间页终止序号
- * */
- protected $endPage;
- /**
- *int 记录总数
- * */
- protected $recorbTotal;
- /**
- *int 每页显示记录数
- * */
- protected $pageSize;
- /**
- *int 当前显示页
- * */
- protected $currentPage;
- /**
- *string 基url地址
- * */
- protected $baseUri;
- /**
- * @return string 获取基url地址
- */
- public function getBaseUri() {
- return $this->baseUri;
- }
- /**
- * @return int 获取当前显示页
- */
- public function getCurrentPage() {
- return $this->currentPage;
- }
- /**
- * @return int 获取每页显示记录数
- */
- public function getPageSize() {
- return $this->pageSize;
- }
- /**
- * @return int 获取记录总数
- */
- public function getRecorbTotal() {
- return $this->recorbTotal;
- }
- /**
- * @param string $baseUri 设置基url地址
- */
- public function setBaseUri($baseUri) {
- $this->baseUri = $baseUri;
- }
- /**
- * @param int $currentPage 设置当前显示页
- */
- public function setCurrentPage($currentPage) {
- $this->currentPage=$currentPage;
- }
- /**
- * @param int $pageSize 设置每页显示记录数
- */
- public function setPageSize($pageSize) {
- $this->pageSize = $pageSize;
- }
- /**
- * @param int $recorbTotal 设置获取记录总数
- */
- public function setRecorbTotal($recorbTotal) {
- $this->recorbTotal = $recorbTotal;
- }
- /**
- *构造函数
- * */
- public function __construct()
- {
- $this->pageTotal = 0;
- $this->previous = 0;
- $this->next = 0;
- $this->startPage = 0;
- $this->endPage = 0;
- $this->pageSize = 20;
- $this->currentPage = 0;
- }
- /**
- *分页算法
- * */
- private function arithmetic() {
- if ($this->currentPage
- $this->currentPage = 1;
- $this->pageTotal = floor ( $this->recorbTotal / $this->pageSize ) + ($this->recorbTotal % $this->pageSize > 0 ? 1 : 0);
- if ($this->currentPage > 1 && $this->currentPage > $this->pageTotal)
- header ( 'location:' . $this->baseUri . 'page=' . $this->pageTotal );
- $this->next = $this->currentPage + 1;
- $this->previous = $this->currentPage - 1;
- $this->startPage = ($this->currentPage + 5) > $this->pageTotal ? $this->pageTotal - 10 : $this->currentPage - 5;
- $this->endPage = $this->currentPage $this->currentPage + 5;
- if ($this->startPage
- $this->startPage = 1;
- if ($this->pageTotal $this->endPage)
- $this->endPage = $this->pageTotal;
- }
- /**
- *分页样式
- * */
- protected function pageStyle() {
- $result = "共" . $this->pageTotal . "页 ";
- if ($this->currentPage > 1)
- $result .= " . $this->baseUri . "page=1/">9 . $this->baseUri . "page=$this->previous/">3";
- else
- $result .= "9 3";
- for($i = $this->startPage; $i $this->endPage; $i ++) {
- if ($this->currentPage == $i)
- $result .= " $i";
- else
- $result .= " . $this->baseUri . "page=$i/">$i";
- }
- if ($this->currentPage != $this->pageTotal) {
- $result .= " . $this->baseUri . "page=$this->next/">4";
- $result .= " . $this->baseUri . "page=$this->pageTotal/">:";
- } else {
- $result .= " 4 :";
- }
- return $result;
- }
- /**
- *执行分页
- * */
- public function execute() {
- if ($this->baseUri != "" && $this->recorbTotal == 0)
- return "";
- $this->arithmetic();
- return $this->pageStyle ();
- }
- }
调用代码(test.php 代码如下)
- include_once 'Pager.class.php';
- $pager=new Pager();
- if (isset ( $_GET ['page'] ) && ! emptyempty ( $_GET ['page'] ))
- $pager->setCurrentPage($_GET ['page']);
- else
- $pager->setCurrentPage(1);
- $pager->setRecorbTotal(1000);
- $pager->setBaseUri("test.php?");
- echo $pager->execute();
数据库结合 mysql 通用存储过程分页 海量数据分页 就是一个完美的分页了
我们还可继承 Pager 类重写pageStyle方法就可以有不同的样式了. yes ok

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.
