The array look like this ,I used the sample of php.net to loop through the array to get key and value
0 : a
0 : subA
1 : subB
0 : subsubA
1 : subsubB
0 : deepA
1 : deepB
unfortunately I got nothing response, anyone can help will be appaeciate
$iterator = new RecursiveArrayIterator($myArray);
iterator_apply($iterator, 'traverseStructure', array($iterator));
function traverseStructure($iterator) {
while ( $iterator -> valid() ) {
if ( $iterator -> hasChildren() ) {
traverseStructure($iterator -> getChildren());
}
else {
echo $iterator -> key() . ' : ' . $iterator -> current() .PHP_EOL;
}
$iterator -> next();
}
}

Answer 1

function DFS($array) {
foreach ($array as $k => $v) {
if (is_array($v)) {
$this->DFS($v);
}
else echo '<br />'. $k. ' - '. $v;
}
}
