How to change the value in the array, with the condition on the key

Question

Good day. Can not catch up with how to do. An array is formed dynamically. He may be so

one.

[f_i] => Array ( [1] => Array ( [1] => fld_img [2] => page [3] => article ) [2] => 0 )

2

 [f_i] => Array ( [1] => 0 [2] => 0

3

  [f_i] => Array ( [1] => 0 [2] => Array ( [1] => fld_img2 [2] => page [3] => article ) )

Took only two keys and 4 states. I need to convert an array to such a view.

If value == 0, then do not touch. If the value is an array, then the value is equal to the key. That is, it should work, so in the first case.

one.

 [f_i] => Array ( [1] => 1 [2] => 0 )

Thank you in advance.

You can pass an array with a foreach loop and check the values of its elements with the is_array function. If it is an array, replace it with a key. Suppose $ arr is your array, then the loop will look like this:

 foreach ($arr as $key => $value) { if(is_array($value)) $arr[$key] = $key; }

I can't add plus yet, rating is less than 15. I forgot about is_array completely.
The author of the question may mark the answer as correct without any restrictions on rating;)
