style='width:60px;float:$f;' 这里者型的郑租$f变量喊嫌兆放在单引号中，php不是解析不了吗？把$f拿出来然后拼接一下吧， style='width:60px;float:‘“.$f.";
可以使用flexslider ，代码和下边类山卜似
div class="slider"
div class="flexslider flexslider2"
ul class="slides item"
?php foreach($slide as $v) { ?
lia target="_bland" href="?php echo $v['Url']; ?"逗物穗img src="蚂悄?php echo '../'.$v['ImagePath']; ?" width="960" height="250"/a/li
?php } ?
/ul
/div
