老板说：
我要一行5个商品，每个长得都不一样
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>练习</title>
<style>
li{list-style: none;}
.slide-content li{float:left;100px;height:100px;border:1px solid #000;margin:5px;line-height: 100px;color:#000;text-align: center;}
.li-1{background:red;}
.li-2{background:yellow;}
.li-3{background:blue;}
.li-4{background:green;}
.li-5{background:gray;}
</style>
</head>
<body>
<?php
//商品组至少5个噢
$items=array(
array("name"=>"product1","price"=>10),
array("name"=>"product2","price"=>20),
array("name"=>"product3","price"=>30),
array("name"=>"product4","price"=>40),
array("name"=>"product5","price"=>10)
);
//一行显示5个
$li_n=5;
//宝贝数
$p_num=count($items)+1;
//循环的ul数，cei(1.5)=2
$ul_n=ceil($p_num/$li_n);
for($i=1;$i<$ul_n;$i++){
$li_nav=1;
echo '<ul class="slide-content">';
foreach($items as $key => $item){
/*listart*/
$s_n=$key+1;
$end_q=$i*$li_n;
$star_q=$end_q-$li_n;
/*1-5,5-10,10-15等，li_nav每次从1开始*/
if($s_n>$star_q and $s_n<=$end_q){
echo '<li class="li-'.$li_nav.'">'.$item['name'].'</li>';
$li_nav++;
}
/*liend*/
}
echo '</ul>';
}
?>
</body>
</html>
但是，我不会告诉你我有更好的方法>>使用array_chunk()数组分割
