为什么div不会循环我手动复制可以哦用for就不行了

回复讨论(解决方案)

for($i=0;$i<3;$i++)

for($i=0;$i<$num;$i++)
两个$i了

for($i=0;$i<3;$i++)

for($i=0;$i<$num;$i++)
两个$i了刚改了发现不一样啊复制了好多好多

循环时把变量名注意一下，不要弄重了

if($_MODULE[huoqubaobei]!="4"){    $i=-1;    foreach($items as $item){        $i++;        $itemUrl = $uriManager->detailURI($item);         $itemPicUrl = $item->getPicUrl(310);        $itemTitle = $item->title;        $itemPrice = $item->price;        $itemsoldCount = $item->soldCount;

Copy after login

foreach里的$i每循环一次+1，但你的外层for循环$i不能超过三，所以，你的foreach的$i影响了for的$i，也就循环一次了
