Multidimensional Arrays Nested to Unlimited Depth

Question

I have a multidimensional array nested to an unknown/unlimited depth. I\'d like to be able to loop through every element. I don\'t want to use, foreach(){foreach(){for

Answer 1

There is a vast difference between unknown and unlimited. However, you can make use of the SPL Iterators instead of using multiple nested foreach loops.

Example:

$array_obj = new RecursiveIteratorIterator(new RecursiveArrayIterator($array));
foreach($array_obj as $key => $value) {
   echo $value;
}
