各位朋友大家好！
本日给大家带来的是一款 供PHP初学者学习的分页类库
分页显示模板，可用变量参数。当前选中的分页链接模板，未选中的分页链接模板。显示文本设置，设置分页模板， 设置选等分页模板，设置未选等分页模板。
由于源码比较长，想要文件版源码的可以评论或者私聊
废话不多说，上源码！

分页类
利用办法:
$page = new Page();
$page->init(1000, 20);
$page->setNotActiveTemplate('<span> {a} </span>');
$page->setActiveTemplate('{a}');
echo $page->show();
/
class Page {
/
总条数
/
private $total;
/
每页大小
/
private $pageSize;
/
总页数
/
private $pageNum;
/
当前页
/
private $page;
/
地址
/
private $uri;
/
分页变量
/
private $pageParam;
/
LIMIT XX,XX
/
private $limit;
/
数字分页显示
/
private $listnum = 8;
/
分页显示模板
可用变量参数
{total} 总数据条数
{pagesize} 每页显示条数
{start} 本页开始条数
{end} 本页结束条数
{pagenum} 共有多少页
{frist} 首页
{pre} 上一页
{next} 下一页
{last} 尾页
{list} 数字分页
{goto} 跳转按钮
/
private $template = '<div><span>共有{total}条数据</span><span>每页显示{pagesize}条数据</span>,<span>本页{start}-{end}条数据</span><span>共有{pagenum}页</span><ul>{frist}{pre}{list}{next}{last}{goto}</ul></div>';
/
当前选中的分页链接模板
/
private $activeTemplate = '<li class=\公众active\"大众><a href=\公众javascript:;\"大众>{text}</a></li>';
/
未选中的分页链接模板
/
private $notActiveTemplate = '<li><a href=\"大众{url}\"大众>{text}</a></li>';
/
显示文本设置
/
private $config = array('frist' => '首页', 'pre' => '上一页', 'next' => '下一页', 'last' => '尾页');
/
初始化
@param type $total 总条数
@param type $pageSize 每页大小
@param type $param url附加参数
@param type $pageParam 分页变量
/
public function init($total, $pageSize, $param = '', $pageParam = 'page') {
$this->total = intval($total);
$this->pageSize = intval($pageSize);
$this->pageParam = $pageParam;
$this->uri = $this->geturi($param);
$this->pageNum = ceil($this->total / $this->pageSize);
$this->page = $this->setPage();
$this->limit = $this->setlimit();
}
/
设置分页模板
@param type $template 模板配置
/
public function setTemplate($template) {
$this->template = $template;
}
/
设置选等分页模板
@param type $activeTemplate 模板配置
/
public function setActiveTemplate($activeTemplate) {
$this->activeTemplate = $activeTemplate;
}
/
设置未选等分页模板
@param type $notActiveTemplate 模板配置
/
public function setNotActiveTemplate($notActiveTemplate) {
$this->notActiveTemplate = $notActiveTemplate;
}
/

@return type
/
public function show() {
return str_ireplace(array(
'{total}',
'{pagesize}',
'{start}',
'{end}',
'{pagenum}',
'{frist}',
'{pre}',
