老师批语:
原则是用冒号:替换掉{}
if (true) {echo 'xxx';} else {echo 'xxxx';}// 替换语法if (true) :echo 'xxx';else :echo 'xxxx';endif;if (true) :echo 'xxx';elseif (true) :echo 'xxxx';elseif (true) :echo 'xxxx';endif;switch (true) :case 'xxx'://....break;case 'xxx'://....break;case 'xxx'://....break;default://...endswitch;while (true) {//...}while (true) ://...endwhile;for (;;) {//....}for (;;) ://....endfor;foreach ($data as $k=>$v) {}foreach ($data as $k=>$v) :endforeach;

<?php// 导入外部数据$news = require 'data/news.php';?><div class="news"><h3>新闻列表</h3><div class="list"><?php foreach ($news as $new) :if($new['id'] <= 5) :?><a href="<?=$new['url'] ?>"><?=$new['title'] ?></a><?php endif; endforeach ?></div></div>

<?php// 当然,也可以在循环体直接写for(i=1;i<=8;i++);不用在这里定义了$products = [1,2,3,4,5,6,7,8];?><div class="items"><h3>产品列表</h3><div class="list"><?php foreach ($products as $product) : ?><div class="item"><img src="static/images/item<?=$product ?>.jpeg" alt="" /><a href="">最新产品<?=$product ?></a></div><?php endforeach ?></div></div>
