Demo link : http://client.bfm.expert/test_unilevel1.php
Code :

//Use the following function to get the data of downlines
function getChildren($parent) {
//list out members by rank
$query = "SELECT user_id, first_name, sponsor_id, rank FROM tbl_user_master WHERE sponsor_id = $parent";
$result = $conn->query($query);
$children = array();
$i = 0;
$result = $conn->query($query) or die($conn->error);
while($row = $result->fetch_assoc())
{
$children[$i] = array();
$children[$i]['userid'] = $row['user_id'];
$children[$i]['name'] = $row['first_name'];
$children[$i]['rank'] = $row['rank'];
$children[$i]['children'] = getChildren($row['user_id']);
$i++;
}
return $children;
}
//modify rank = 4 to 2 to calculate unilevel bonus for rank IAM
$query2 = "SELECT user_id, first_name FROM tbl_user_master WHERE rank = 3";
$result2 = $conn2->query($query2);
$result2 = $conn2->query($query2) or die($conn2->error);
while($row2 = $result2->fetch_assoc())
{
$member_id = $row2['user_id'];
$member_name = $row2['first_name'];
$finalResult = getChildren($member_id); //enter sponsor_id here
echo "Unilevel Bonus for user id : " . $member_id . " " . $member_name . " - Total Unilevel Bonus for lvl1 : Usd??? , lvl2 : Usd???, lvl3 : Usd??? <br /> ";
printList($finalResult);
}
//display all downlines of the sponsor
function printList($array = null, $level = 1) {
$m_profit = 168000;
$Total_investment = 1500000;
$unibonus_percent = 0.00;
if (count($array)) {
echo "<ul>";
foreach ($array as $item) {
echo "<li>";
echo $item['name'];
echo " - Rank : " . $item['rank'];
echo " - level : " . $level;
//show unilevel bonus
$unibonus_percent = 0.06;
//show how many package_lot
$userid = $item['userid'];
$query3 = "SELECT user_id, package_id, package_amount FROM tbl_product_order WHERE user_id = $userid && status=3";
$result3 = $conn3->query($query3);
$result3 = $conn3->query($query3) or die($conn3->error);
while($row3 = $result3->fetch_assoc()) {
$package_siz = $row3['package_amount'] / 1500;
echo " - LOT : " . $package_siz;
$unibonus = (($m_profit / ($Total_investment / 1500)) * $unibonus_percent) * $package_siz;
echo " - unibonus : USD" . $unibonus;
}
if (count($item['children'])) {
printList($item['children'], $level+1);
}
echo "</li>";
}
echo "</ul>";
}
}

Use call by refrence for total bonus calculation
here is an example
$Bonus = 0;
printList($array = null, 1, $Bonus);
echo $Bonus;
function printList($array = null, $level = 1, &$Bonus = 0) {<---call by referance for bonus
if ($level == 10) {
return; //only for break recursive
}
$Bonus = $Bonus + $level;
printList($array = null, $level + 1, $Bonus);
}
