Foreach Loop Question

[ds111]

Hi!

I have an array like this:

 

[test1] =>
[test2] =>
[test3] => Array
    (
        [archives] => Array
            (
                [file] => application/hooks/archives.php
                [function] => archives
            )

    )

 

How can I make a foreach loop so that it takes the "archives" text out of test 'test3' index? Afterwards, I then need to take the "file" and "function" out, also in the foreach loop.

 

I also need an "if" statement, to check if there is anything in the 'test1' index as well.

All 3 indexes will be called, and I need to loop through each of them. If there is anything there, I need to loop through those, and include the "file" one.

Sorry, (can't edit post).

 

If it's in a for loop, that's even better

You just need a check to see if the inner value is an array. eg;

 

foreach ($arr as $k => $v) {
  if (is_array($v)) {
    foreach ($b as $key => $val) {
      //
    }
  }
}

 

If your going to go any deeper than that you might want to look into recursion.
