php练习:每5个商品一排
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;width: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
