楼上正解
$w= $db->fetchOne($sql); 你这里取到也就是只有一条记录呀,兄弟,你要这样$db->fetchAll($sql);取到的才是所有记录呀,
用新浪的现成的JS特效实现。JS的参数都有提示，很简单<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

应该使用JS来实现，代码如下：
<div id=iii></div>
<input type=button onClick='show_img(-1);' value='左'>
<input type=button onClick='show_img(1);' value='右'>
<script type=text/javascript>
//把图片的地址写在下面，有多少写多少，程序自动适应，注意引号配对
var imgs=['1.jpg', '2.jpg', 'abc.gif', 'def.jpg', 'a.jpg', 'b.jpg'];
var start_num=0;
function show_img(x){
var s='';
start_num+=x;
for (i=start_num;i<start_num+4;i++) s+='<img src="'+imgs[i % imgs.length]+'">';
document.getElementById('iii').innerHTML=s;
}
show_img(0);
</script>
javascript+php只知道这些了
