This example demonstrates using the getDepth() method with a RecursiveArrayIterator.
<?php
$tree = array();
$tree[1][2][3] = 'lemon';
$tree[1][4] = 'melon';
$tree[2][3] = 'orange';
$tree[2][5] = 'grape';
$tree[3] = 'pineapple';
print_r($tree);
$arrayiter = new RecursiveArrayIterator($tree);
$iteriter = new RecursiveIteratorIterator($arrayiter);
foreach ($iteriter as $key => $value) {
$d = $iteriter->getDepth();
echo "depth=$d k=$key v=$value\n";
}
?>
The output of this would be:
Array
(
[1] => Array
(
[2] => Array
(
[3] => lemon
)
[4] => melon
)
[2] => Array
(
[3] => orange
[5] => grape
)
[3] => pineapple
)
depth=2 k=3 v=lemon
depth=1 k=4 v=melon
depth=1 k=3 v=orange
depth=1 k=5 v=grape
depth=0 k=3 v=pineapple
