显然，您试图在不知道如何安全地使用MySQL（或者根本不知道：）的情况下使用MySQL
我建议您学习MySQL或使用一些ORM-您会发现它们可以帮助您专注于逻辑编码，而不是繁琐的查询编写
我所知道的最好的ORM是RedBeanPHP——它小巧、快速且易于使用
它也很灵活-在开发之前不必设计数据库布局，需要向表中添加字段吗？没问题，只要$object->newfield=“嗨！”
而且它与数据库无关（：D）-如果您的客户机选择切换到PostgreSQL或其他版本，您可以使用一行代码进行迁移
试一试。您正在使用并且应该使用。你也很容易受到现代API的影响，因为它会让你更容易使用。卷起袖子，让他们进入PDO，用php代码进行数据库操作不是一个很好的选择；构建一些中间件，让你的页面与之交互。你在这里做的是鲁莽的，会让你被烧死，因为你显然忘记了和。在编写另一行MySQL接口代码之前，您应该了解更多这些。您不能像这样编写代码并期望它正常工作。
