//Use the following function to get the data of downlines

//enter sponsor_id here, change 151 to 145 has a lot of downlines to test
$finalResult = getChildren(145);
//display all downlines of the sponsor
function printList($array = null) {
if (count($array)) {
echo "<ul>";
foreach ($array as $item) {
echo "<li>";
echo $item['name'];
echo " - level : ";
if (count($item['children'])) {
printList($item['children']);
}
echo "</li>";
}
echo "</ul>";
}
}
printList($finalResult);

You need to pass level into 'printList' function and increment it after.
function printList($array = null, $level = 1) {
if (count($array)) {
echo "<ul>";
foreach ($array as $item) {
echo "<li>";
echo $item['name'];
echo " - level : " . $level;
if (count($item['children'])) {
printList($item['children'], $level+1);
}
echo "</li>";
}
echo "</ul>";
}
}
printList($finalResult, 1);
