下面的脚本有一个奇怪的问题。我整天都在努力。我正在尝试在 Magento 购物车的产品视图页面的侧栏中显示每个类别的畅销商品。此脚本在 IE（全部）中有效，但不一样。实际上 IE 做对了，而我尝试过的所有其他浏览器都做错了。
这就是问题所在。它是 php，而 php 应该是一种服务器端语言。但似乎 IE 收到了不同的信息。在下面，您会注意到我在一个部分周围有一个红色边框，在另一部分周围有一个绿色边框。IE 得到红色边框，其余的得到绿色边框。红色边框具有“类别名称”，它在 IE 中工作，但绿色边框......如果我为类别名称放置脚本，它会打印一条错误消息。
除了我得到的多个“被零除”警告（不知道为什么）我想知道如果 php 是一种服务器端语言，为什么两种浏览器会收到两条不同的消息！？
谢谢
