<?php
$jsu = isset($_REQUEST['jsu']) ? $_REQUEST['jsu'] : 1;
$name = $_GET['name'];
$x=0;
$sql = "select * from `a_gytvurl` where `id` = '".$id."' order by `Set` limit 0,300";
$result = mysql_query($sql) or die("<br>读取集数数据库错误！<br>");
if ($num = mysql_num_rows($result)){
while ($row = mysql_fetch_array($result)) {
$x++;
if($jsu == $x){
$clss= "current";
}else{
$clss= "";
}

echo '<li class="'.$clss.'"><a href="./play.php?id='.$row['id'].'&name='.rawurlencode($name).'&jsu='.$x.'&type=tv">'.$x.'</a> </li>';

}
}
