根据GEO位置从不同目录中选择随机图像 [英] Picking a random image out of different directories based on GEO locations

问题描述

从目录中挑选随机图像的代码非常简单。

The code for picking an random image out of a directory is pretty straight forward.

例如；我当前的代码是：

For example; my current code is this:

<?php
$imagesDir = 'img/';
$images = glob($imagesDir . '*.{jpg,jpeg,png,gif}', GLOB_BRACE);
$randomImage = $images[array_rand($images)]; // See comments
?>

我想使用Cloudflare的GEO IP查找程序，因此，当用户访问网站时，它会在

I want to use Cloudflare's GEO IP finder, so when the user visits the website it feeds back where the users from.

所以我想说

  if england use directory > img/en/ 
  if australia use directory > img/au/
  if USA use directory > img/usa/
  if NZ use directory > img/nz/
  if any other country > img/

我知道它的逻辑，但是将其放入代码中是我要做的另一件事

I know the logic to it, but putting it into code is another thing which i've been struggling to do.

有什么想法吗？

推荐答案

创建一个位置目录及其对应名称的数组，然后根据地理位置（在我的示例中为 $ location ）构建图像目录。

Create an array of the location directories and their corresponding names then build your image directory based on the geo location ($location in my example).

$location = 'australia';

$dirs = array('england'   => 'en',
              'australia' => 'au',
              'USA'       => 'usa',
              'NZ'        => 'nz');

$imagesDir = 'img/' . (isset($dirs[$location]) ? $dirs[$location] . '/' : '');

如果在数组中未找到位置，则 $ imagesDir的设置变量将默认为 img / 。

If a location is not found in the array the setting of the $imagesDir variable will default to img/ as it is now.
