Finding the key of a value of an array when that value is an array

[gwolgamott]

Running a recursive function iterating through an array.

So I get the values as needed, but I need somehow to put into this function the key of that value...

 

for example have this array

Array ( [Man Sys Do] => Array (  
                      [Random] => Array ( [0] => LINK_ME ) 
                      [s  & R] => Array (
                             [Recieving] => Array ( [0] => LINK_ME ) 
                              [shipping] => Array ( [0] => LINK_ME ) 
                                                 ) 
                                                 )
        )

 

How do find out that after going through a function to print this or whatever and say I have the LINK_ME how do I then afterwards before leaving my function determine what its key was and if that key had a key itself and so on...  so I can get something like this  "Man Sys Do" : "S & R" : "Shipping" -> LINK_ME

 

EDIT: would this best be done with a variable passed to my recursive function?

answered my own question... in case anyone was interested here are two lines to do that. 

  						$key_sub = $key_sub."/".$key;
  						Nav_Link($value, $key_sub);
