What is the best way to do the following:

I get a path with an AJAX request

e.g. dir1/dir2/dir3/dir4

I need to present it like this on my webpage:

dir1 >> dir2 >> dir3 >> dir4

each of them being html anchor tags with the href attribute being

/dir1

/dir1/dir2

/dir1/dir2/dir3

/dir1/dir2/dir3/dir4

respectively

What is the most elegant and efficient way to achieve this?

so far, I'm doing something like this which i think is really dirty:

<?php 
$dirs = explode(PATH_SEPARATOR, $this->metadata["path"]);
    foreach ($dirs as $key=>$val) {
             if ($val == '') {
                 continue;
             }
             $pathArray = array();
             for ($i = 0; $i <= $key; $i++) {
                 array_push($pathArray, $dirs[$i]);
             }
             $path = implode('/', $pathArray);
             echo " >> <a href=" . $path . ">" . truncate($val) . "</a>";
    }
    ?>
php path split
