所以，我想这是你的问题的解决方案。
我建议您研究代码，从中学习并增强它；-)。而且，我很高兴从您那里得到一些反馈！
数据库使用与您在问题中描述的相同的项目名称和项目类型。
脚本index.php在顶部有一个配置部分，您应该根据需要修改参数。
这些是脚本的块：
- 连接到数据库
- 初始化
- 准备标题
- 从数据库中获取数据
- 准备内容，格式化数据
- 读取模板并替换变量
- 发送生成的输出
输出布局为与电视节目的不同持续时间相对应的可变宽度的 DIV。宽度以百分比计算，这使得布局以某种方式响应不同的屏幕尺寸。
覆盖 DIV 显示当前时间的标记。
如您所见，我使用了一个包含变量引用的模板tvprogramme.tpl：变量名包含在大括号中，例如{{varname}}。脚本最后将这些替换为运行时值。
您可以在模板中找到样式定义 (CSS)，以及以可配置的时间间隔刷新页面的脚本。如果需要，您可以使用 AJAX 调用来刷新页面的某些部分。当然，样式和 javascript 定义也可以保存在单独的文件中。
我建议将两个文件（index.php、tvprogramme.tpl）都存储为 UTF-8 格式，没有 BOM。由于您可能生活在 7 位世界中，因此当文件以 ANSII 格式存储时，该解决方案也可能正常工作。
