Let me share with you another one that is mainly used for novices to learn PHP paging. The code is simple and practical, and the comments are complete.

1. Page.class.php

<&#63;php
/**
 * 分頁類
 * 
 * 調(diào)用方式：
 * $p=new Page(總頁數(shù),顯示頁數(shù),當(dāng)前頁碼,每頁顯示條數(shù),[鏈接]);
 * print_r($p->getPages()); //生成一個頁碼數(shù)組（鍵為頁碼，值為鏈接）
 * echo $p->showPages(1); //生成一個頁碼樣式（可添加自定義樣式）

/*
思路：
給我一個 總頁數(shù)，需要顯示的頁數(shù)，當(dāng)前頁，每頁顯示的條數(shù)，連接
寫一個方法 生成一個一維數(shù)組，鍵為頁碼 值為連接
寫一個方法 返回一個生成好樣式的頁碼（并且可以根據(jù)自己需要添加樣式）
默認樣式 共45條記錄,每頁顯示10條,當(dāng)前第1/4頁 [首頁] [上頁] [1] [2] [3] .. [下頁] [尾頁]
