[RESOLVED] loop through an array help

[condoug]

Hi all

This is probably very basic stuff for most of you!

I have this array which i have printed out:

Array
(
    [mother] => Array
        (
            [sister] => 
            [brother] => 
        )

[father] => Array
    (
        [brother] => 
        [cousin] => 
    )

[grandad] => 
)

I need some code which will loop through the array above and display each element in the array accordingly, however, each time i try the following:

	foreach ($array as $key => $value) {
		echo "Key: $key <br />";
	}

I only get the top three elements (mother, father and grandad).

How can I get it to display them all irrelevant of how deep the array might go?

Thankyou
Doug.

foreach($array as $key => $value) {
   echo "Key: $key <br />\n";
   if(is_array($value)){
      foreach($value as $key2 => $value2) {
         echo "  Sub-Key: $key2 <br />\n";
      }
   }
}

If there could be multiple levels of arrays, you might need to come up with a recursive function to walk through all of them.

Have a look at the array_walk_recursive function:-

http://www.php.net/manual/en/function.array-walk-recursive.php

The main example at the top of that page should be of use, or should require minimal tinkering to do what you want it to. It will cope with multiple levels of array depth.

Thank you for your speedy responses. I have implemented NogDog's solution for the time being and it works great.

There is a chance that the array will go deeper so thank you for the pointer regarding the array_walk function also.
