我从网上获得了这些代码，并成功地将它们组合在一起以按我的意愿工作。从一个简单的 php 搜索开始...

搜索脚本 - http://php.about.com/od/phpwithmysql/ss/php_search.htm

google…mysql 匹配

自己的工作 - 成功尝试区分大小写的过滤器

突出显示搜索词（从这里 stackoverflow） - mysql 和 php 搜索突出显示

感谢那些在网上分享这些代码的人，感谢你在 stackoverflow 上的广泛知识。

现在有了代码，在我得到结果后，我想有一个更新葡萄酒库存的选项。我不知道从哪里开始，也找不到学习的例子。请指导我正确的方式。谢谢你。

这是下一个需要该代码的人的完整代码。
