Needed to recursively loop through a multi-dimensional array and print out each leaf-node with its full “path”.
For this I used a RecursiveArrayIterator for the array and a RecursiveIteratorIterator for the recursion. Thought I was home free because I had used a method called
getSubpathname before, but turned out that was just something the RecursiveDirectoryIterator had…
So, had to grow my own… noting it here for others and the future:
* Gets the path to current node, i.e. each
* key "upwards", including self.
* @param null|string $glue Optional $glue for implode().
* @return array|string The keys, from root to self,
* as an array; or as a string if $glue is provided.
public function getPath($glue = null)
for($i = 0; $i < $this->getDepth(); $i++)
$path = $this->getSubIterator($i)->key();
$path = $this->key();
return $glue !== null
? implode($glue, $path)
