从文件夹获取相对路径答案

【问题标题】：Getting relative path from folder从文件夹获取相对路径

【问题描述】：

我的文件管理器文件夹位于此处：

localhost/cakeapp/app/webroot/js/tinymce/js/tinymce/plugins/filemanager/

在 cakeapp 根目录下，我有两个文件夹：

uploadedImages (cakeapp/uploadedImages)
UploadedImagesThumbs (cakeapp/uploadedImagesThumbs).

我在config.php文件中有这种情况：

$base_url ="http://localhost";

// path from base_url to base of upload folder (with start and final /)
$upload_dir = '/cakeapp/uploadedImages/';

// relative path from filemanager folder to thumbs folder (with final /)
$thumbs_base_path = '???????/uploadedImagesThumbs'; 

// relative path from filemanager folder to upload folder (with final /)
$current_path = '???????/uploadedImages/';

如何从 filemanager 文件夹中获取 $thumbs_base_path 和 $current_path 的正确相对路径？

【问题讨论】：

$thumbs_base_path = '../../../../../../../../uploadedImagesThumbs/';?
谢谢，它有效！当我试图解决这个问题时，我做了七次'../'而不是八次。
这看起来不像是好的编码......

【解决方案1】：

你可以试试

function getRelativePath($from, $to) {
$patha = explode('/', $from);
$pathb = explode('/', $to);
$start_point = count(array_intersect($patha,$pathb));
while($start_point--) {
    array_shift($patha);
    array_shift($pathb);
}
$output = "";
if(($back_count = count($patha))) {
    while($back_count--) {
        $output .= "../";
    }
} else {
    $output .= './';
}
return $output . implode('/', $pathb);
}

查看source。它还有更多示例
