How to use array_walk_recursive

Question

How can I use array_walk_recursive() instead of this:

function check_value($val){
  if(is_array($val)){
    foreach($val as $key => $value)
          


        

Answer 1

This should work:

function check_value ( $val ) {
    if ( is_array ( $val ) ) array_walk_recursive ( $val, 'check_value' );
    return clean_value ( $val );
}
