本文实例为大家分享了PHP实现可自定义样式的分页类,供大家参考,具体内容如下
<?php //namespace Component; /** * 2016-3-27 * @author ankang */ class Page { private $ShowPage; private $CountPage; private $Floorp; private $PageUrl; private $PageClass; private $CurClass; /** * @author ankang * @param number $CountNum 数据总数 * @param string $PageUrl 跳转链接 * @param string $PageClass <a>标签 总体样式 * @param string $PageUrl 当前页样式 * @param number $PageSize 每页显示的数据条数 * @param number $ShowPage 每次显示的页数 */ public function __construct($CountNum, $PageUrl = NULL, $PageClass = NULL,$CurClass = NULL, $PageSize = 20, $ShowPage = 5) { $this->ShowPage = $ShowPage; $this->CountPage = ceil ( $CountNum / $PageSize ); $this->Floorp = floor ( $ShowPage / 2 ); // 偏移量 $this->PageClass = is_null ( $PageClass ) ?

再为大家分享一个主要用于新手学习php分页,代码简单实用,主要是注释很完整。
1. Page.class.php
<?php /** * 分页类 * * 调用方式: * $p=new Page(总页数,显示页数,当前页码,每页显示条数,[链接]); * print_r($p->getPages()); //生成一个页码数组(键为页码,值为链接) * echo $p->showPages(1); //生成一个页码样式(可添加自定义样式) * * @author: Dzer <Email:358654744@qq.com Blog:Dzer.me> * @version: 2014-12-25 09:09:42 * @Last Modified time: 2014-12-28 17:37:13 */ /* 思路: 给我一个 总页数,需要显示的页数,当前页,每页显示的条数,连接 写一个方法 生成一个一维数组,键为页码 值为连接 写一个方法 返回一个生成好样式的页码(并且可以根据自己需要添加样式) 默认样式 共45条记录,每页显示10条,当前第1/4页 [首页] [上页] [1] [2] [3] ..

2. demo.php
<?php /** * 分页类demo * Be the best of whatever you are! * * @author: Dzer<358654744@qq.com> * @version: 2014-12-28 17:38:23 * @Last Modified time: 2014-12-28 18:08:28 */ header("content-type:text/html;charset=utf8"); include('./Page.class.php'); //引入类 //$p=new Page(总页数,显示页数,当前页码,每页显示条数,[链接]); //连接不设置则为当前链接 $page=isset($_GET['page']) ? $_GET['page'] : 1; $p=new Page(100,7,$page,8); //生成一个页码数组(键为页码,值为链接) echo "<pre class="brush:php;toolbar:false">"; print_r($p->getPages()); //生成一个页码样式(可添加自定义样式) //样式 共45条记录,每页显示10条,当前第1/4页 [首页] [上页] [1] [2] [3] ..

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,

A string is a sequence of characters, including letters, numbers, and symbols. This tutorial will learn how to calculate the number of vowels in a given string in PHP using different methods. The vowels in English are a, e, i, o, u, and they can be uppercase or lowercase. What is a vowel? Vowels are alphabetic characters that represent a specific pronunciation. There are five vowels in English, including uppercase and lowercase: a, e, i, o, u Example 1 Input: String = "Tutorialspoint" Output: 6 explain The vowels in the string "Tutorialspoint" are u, o, i, a, o, i.

These methods are automatically called in certain situations, improving code flexibility and efficiency.
