使用 PHP 进行高效的横幅旋转 [英] Efficient banner rotation with PHP

问题描述

我通过从一系列横幅中随机选择一个横幅来旋转我网站上的横幅.

I rotate a banner on my site by selecting it randomly from an array of banners.

示例代码作为演示:

<?php
$banners = array(
'<iframe>...</iframe>',
'<a href="#"><img src="#.jpg" alt="" /></a>',
//and so on
);
echo $banners(rand(0, count($banners)));
?>

横幅的排列变得相当大.我关心这个数组为我的页面的执行添加的内存量.但是我想不出更好的方法来显示随机横幅而不将所有横幅加载到内存中...

The array of banners has become quite big. I am concerned with the amount of memory that this array adds to the execution of my page. But I can't figure out a better way of showing a random banner without loading all the banners into memory...

推荐答案

将横幅移动到 html 文件并将数组更改为仅包含文件名.

Move the banners to html files and change the array to contain only filenames.

然后您可以按名称包含该文件，只加载所需的横幅.

Then you can include that file by the name, only loading the banner required.
