php 自己写的好看的分页类

自己写的一个分页类 ,不是很完整,个别没有做验证,但可以使用,分页效果见文章底部。除了链接数据库的代码没有粘贴上来,其他的都粘贴了。供学习使用~

 <?php
/**

class page {
public $pageSize; //每页显示的文章条数
public $showPage; //页数条显示的条数
public $count; //文章总条数
public $page; //当前页
public $mergyStr; //存储页码的变量
public $skip; //跳转页开关,默认为false关闭 //初始化参数
public function __construct($count, $pageSize = 10, $showPage = 5, $currentPage = 1, $skip = false) {
$this->pageSize = $pageSize;
$this->showPage = $showPage;
$this->count = $count;
$this->page = $this->checkPage($currentPage);
$this->mergyStr = '';
$this->skip = $skip;
} //检查传递的$page的合法性
public function checkPage($currentPage) {
if($currentPage < 1 || empty($currentPage)) {
$currentPage = 1;
}
if($currentPage > $this->totalPages()) {
$currentPage = $this->totalPages();
}
return $currentPage;
} //计算偏移量
public function pageOffset() {
return ($this->showPage-1)/2;
} //计算总页数
public function totalPages() {
return ceil($this->count/$this->pageSize);
} //获取页面URL
public function getPageUrl() {
$CurrentUrl = $_SERVER["REQUEST_URI"];
$arrUrl = parse_url($CurrentUrl);
$urlQuery = $arrUrl["query"]; if($urlQuery){
//print_r($this->page);
$urlQuery = preg_replace("/(^|&)page=/" . $this->page, "", $urlQuery);
$CurrentUrl = str_replace($arrUrl["query"], $urlQuery, $CurrentUrl); if($urlQuery){
$CurrentUrl.="&page";
}
else $CurrentUrl.="page"; } else {
$CurrentUrl.="?page";
} return $CurrentUrl;
} //页码显示行
public function GetPagerContent() {
$start = 1;
$end = $this->totalPages();
$this->mergyStr .= "<div class='page'>";
if($this->page > 1) {
$this->mergyStr .= " <a href='".$this->getPageUrl()."="."1'>首页</a>";
$this->mergyStr .= " <a href='".$this->getPageUrl()."=".($this->page-1)."'>上一页</a>";
}else{
$this->mergyStr .= " <span class='disable'>首页</span>";
$this->mergyStr .= " <span class='disable'>上一页</span>";
} if($this->totalPages() > $this->showPage) {
if($this->page > $this->pageoffset()+1) {
$this->mergyStr .= "...";
} if($this->page > $this->pageoffset()) {
$start = $this->page-$this->pageoffset();
$end = $this->totalPages() > $this->page+$this->pageoffset() ? $this->page+$this->pageoffset() : $this->totalPages();
}
else{
$start = 1;
$end = $this->totalPages() > $this->showPage ? $this->showPage : $this->totalPages();
} if($this->page + $this->pageoffset() > $this->totalPages()) {
$start = $start - ($this->page + $this->pageoffset() - $end);
} } for($i=$start; $i<=$end; $i++) {
if($i == $this->page) {
$this->mergyStr .= "<span class='current'>{$i}</span>";
}else{
$this->mergyStr .= " <a href='".$this->getPageUrl()."=".$i."'>{$i}</a>";
} } if($this->totalPages() > $this->showPage && $this->totalPages() > $this->page + $this->pageoffset()) {
$this->mergyStr .= "...";
} if($this->page < $this->totalPages()) {
$this->mergyStr .= " <a href='".$this->getPageUrl()."=".($this->page+1)."'>下一页</a>";
$this->mergyStr .= " <a href='".$this->getPageUrl()."=".$this->totalPages()."'>尾页</a>";
}else{
$this->mergyStr .= " <span class='disable'>下一页</span>";
$this->mergyStr .= " <span class='disable'>尾页</span>";
} $this->mergyStr .= " 共{$this->totalPages()}页"; //显示跳转框
if($this->skip == true) {
$this->mergyStr .= $this->skipNumPage();
} $this->mergyStr .= "</div>"; print_r($this->mergyStr);
} //跳转页
public function skipNumPage() {
$this->mergyStr .= "<form action='' method='get'>";
$this->mergyStr .= "第<input type='text' name='page' style='width:30px; height:25px; border: 1px solid #aaaadd;'>页";
$this->mergyStr .= "<input type='submit' value='查询' style='border: 1px solid #aaaadd; text-decoration: none; padding:4px 10px 4px 10px; ' >";
$this->mergyStr .= "</form>";
} }

上面是类文件的所有代码,以下是调用实例:

<?php
//数据库链接,不写了 //每页显示条数
$pageSize = 10;
//页码行显示的条数
$showPage = 5;
//当前页
$page = isset($_GET['page']) ? $_GET['page'] : 1; //当前页显示的文章
$sql = "select * from follow_trade_1 order by `follow_trade_id` asc limit ".($page-1)*$pageSize.",{$pageSize}";
$query = mysql_query($sql); //计算总条数
$sql_count = mysql_query("select count(*) from follow_trade_1");
$query_count = mysql_fetch_row($sql_count);
$count = $query_count[0]; //实例化分页类
require("page.php");
$p = new page($count, $pageSize, $showPage, $page, true); //table里的文章数据
echo "<table border='1' style='width:400px;'>";
echo "<tr><td>follow_trade_id</td><td>follow_id</td></tr>";
while($rs = mysql_fetch_assoc($query)) {
echo "<tr><td>{$rs['follow_trade_id']}</td><td>{$rs['follow_id']}</td></tr>";
}
echo "</table>"; //读取分页条
$p->GetPagerContent();

样式CSS:

<style>
div.page{text-align: left; margin-top: 10px;}
div.page a{border: 1px solid #aaaadd; text-decoration: none; padding:2px 10px 2px 10px; margin: 2px;}
div.page span.current{border: 1px solid #000099; background-color: #000099; padding: 4px 10px 4px 10px; margin: 2px; color: #fff; font-weight: bold;}
div.page span.disable{border: 1px solid #eee; padding: 2px 5px 2px 5px; margin: 2px; color: #ddd;}
div.page form{display: inline;}
</style>

效果如图所示:
