问题描述
使用PHP和/或HTML，创建一个页面，该页面以给定的时间间隔在任意数量的其他页面中循环。
例如，我们会加载这个页面，它会把我们带到谷歌20秒，然后到雅虎10秒，然后在180秒等堆栈溢出，等等。

Here's a challenge that I was tasked with recently. I still haven't figured out the best way to do it, maybe someone else has an idea.
Using PHP and/or HTML, create a page that cycles through any number of other pages at a given interval.
For instance, we would load this page and it would take us to google for 20 seconds, then on to yahoo for 10 seconds, then on to stackoverflow for 180 seconds and so on an so forth.

display: function()
{
var dashboard = Dash.dashboards[Dash.nextIndex];
frames["displayArea"].location.href = dashboard.url;
Dash.nextIndex = (Dash.nextIndex + 1) % Dash.dashboards.length;
setTimeout(Dash.display, dashboard.time * 1000);
}
};
