 * page([总记录数=1]，[分页大小=20]，[当前页=1]，[显示页数=6]，[分页参数='page'],[分页链接=当前页面],[是否静态=false])
 * 动态：
 * 简单用法：
 * $page = new page(50);
 * $page->setpager('zjj','

共有{recordcount} 个商品  当前第 {pageindex} 页 / 共 {pagecount} 页 分页： {first}{prev}  {list}  {next}{last}  转到 {jump} 页

',array("listlong"=>"6","first"=>"首页","last"=>"尾页","prev"=>"上一页","next"=>"下一页","list"=>"第*页","jump"=>"select"));
 * echo $page->getpager('zjj');
 * 全参数用法：
 * $page = new page(50,20,1,6,'page','prrr.php',false);
 * $page->setpager('zjj','

共有{recordcount} 个商品  当前第 {pageindex} 页 / 共 {pagecount} 页 分页： {first}{prev}  {list}  {next}{last}  转到 {jump} 页

',array("listlong"=>"6","first"=>"首页","last"=>"尾页","prev"=>"上一页","next"=>"下一页","list"=>"第*页","jump"=>"select"));
 * echo $page->getpager('zjj');
 * 静态：
 * $page = new page(50,20,1,6,'page','prrr{page}.html',true);
 * $page->setpager('zjj','

共有{recordcount} 个商品  当前第 {pageindex} 页 / 共 {pagecount} 页 分页： {first}{prev}  {list}  {next}{last}  转到 {jump} 页

',array("listlong"=>"6","first"=>"首页","last"=>"尾页","prev"=>"上一页","next"=>"下一页","list"=>"第*页","jump"=>"select"));
 * echo $page->getpager('zjj');
