分页显示类

$p->file="ttt.php";  //设置文件名，默认为当前页
$p->pvar="pagecount"; //设置页面传递的参数，默认为p
$p->setvar(array(
"a" => '1',
"b" => '2'
));      //设置要传递的参数,要注意的是此函数必须要在　set 前使用，否则变量传不过去
$p->set(20,2000,1);  //设置相关参数，共三个，分别为'页面大小'、'总记录数'、'当前页(如果为空则自动读取GET变量)'
$p->output(0);   //输出,为0时直接输出,否则返回一个字符串
echo $p->limit();  //输出Limit子句。在sql语句中用法为 "SELECT * FROM TABLE LIMIT {$p->limit()}";
