我正在尝试创建一个页面，在其中输入一个 MYSQL 查询：SELECT column1,column2 FROM table;，并动态创建一个带有列标题的 HTML 表。
编辑：删除了我的大部分问题，只留下了问题部分。从那以后，我创建了一个执行此操作的脚本并将其作为答案包含在内。我希望其他人像我一样使用它（当我懒得登录phpmyadmin时......哈哈哈）。

我会尝试mysql_fetch_assoc返回一个关联数组（地图）。然后您可以使用 array_keys 来获取列名。

这听起来可能与测试有关，有时您只需要吐出结果即可在屏幕上看到它们，所以我将把它放在这里......
php 类 dbug 是一个很棒的工具，可以快速从 php 数组甚至是 MySQL 结果中获取格式良好的表格：

好。以下是我完成此操作的方法，基于 webjprgm 使用 mysql_fetch_assoc 的提示：
