This is what I am trying to accomplish. 1. I have two tables. T1: Users and T2: Earnings. 2. I want to find a single random user whose deposit amount is greater than the listed amount. Below is my foreach loop within foreach loop trying to do the above. I was wondering if there is a more simple way to do this task? Is there a way to combine these two queries together? $listed_amount = 1000; // find a random user $find_user = $db->prepare("SELECT user_id FROM users WHERE user = :user AND active = :active ORDER BY RAND() LIMIT 1"); $find_user->bindValue(':user', 1); $find_user->bindValue(':active', 1); $find_user->execute(); $result_user = $find_user->fetchAll(PDO::FETCH_ASSOC); if(count($result_user) > 0) { foreach($result_user as $row) { $user_id = $row['user_id']; // find that random user's deposit amount $get_deposits = $db->prepare("SELECT deposit FROM earnings WHERE sent_to = :sent_to AND status = :status"); $get_deposits->bindParam(':sent_to', $user_id); $get_deposits->bindValue(':status', 1); $get_deposits->execute(); $result_deposits = $get_deposits->fetchAll(PDO::FETCH_ASSOC); if(count($result_deposits) > 0) { $ub = 0; foreach($result_deposits as $key=>$row) { $ub+= $row['deposit']; } $total_deposits = $ub; } if($total_deposits > $listed_amount) { // show the user } else { // hide the user } } }

Say I have 5 users. Each user will receive their payment based on their individual percentage. For eg. User 1: 5% User 2: 10% User 3: 15% User 4: 15% User 5: 5% Now say I have a total of $100. I want to divide the $100 among the 5 users. But the users with higher % will receive a higher amount than the the ones with lower %. How would I calculate this?

I currently have a php code at the top of the page that would automatically delete a user from the database if a certain condition isn't met before 24 hours. This code is processed no matter where you are on the site. I have two questions. 1. Will this be an issue if the database has thousands of users? 2. Is there a better way to do this?

Say I have this records table. RECORDS TABLE record_id | sponsor_id | user_id | plan_id ------------------------------------------------------------------------------ 1 user5 user6 5 // I am this user. 2 user3 user5 3 3 user3 user4 4 4 user2 user3 4 5 user2 user2 2 6 user0 user1 5 I am "user6" and my sponsor is "user5". What I want to do is find the same "plan_id" from my sponsors, no matter how far up I have to do. For eg. My current plan id is "5". My sponsor is "user5". If I look for "user5" in the user_id column, I would find that he only has plan "3" id. So I go to his sponsor, which is "user3" and find him in the user_id column. That user's plan id is "4" so it does not match my plan id either. I repeat the same process by going to his sponsor and his sponsor and so on until I find the plan id that matches me. So for this table example, that would be "user1". I only want to retrieve the first result that matches my plan id. How do I go on about coding this function? Normally I can do these queries to go up limited amount. But I am looking for a more proper function that lets me search my sponsors unlimited times. $find_plan_id = $db->prepare("SELECT sponsor_id, plan_id FROM records WHERE user_id = :user_id"); $find_plan_id->bindParam(':user_id', $user_id); $find_plan_id->execute(); $result_find_plan_id = $find_plan_id->fetchAll(PDO::FETCH_ASSOC); if(count($result_plan_id) > 0) { foreach($result_plan_id as $row) { $get_sponsor_id_1 = $row['sponsor_id']; $get_plan_id_1 = $row['plan_id']; } if($get_plan_id_1 == $my_plan_id) { echo 'Plan id matches.'; } else { $find_plan_id_2 = $db->prepare("SELECT sponsor_id, plan_id FROM records WHERE user_id = :user_id"); $find_plan_id_2->bindParam(':user_id', $get_sponsor_id_1); $find_plan_id_2->execute(); $result_plan_id_2 = $find_plan_id_2->fetchAll(PDO::FETCH_ASSOC); if(count($result_plan_id_2) > 0) { foreach($result_plan_id_2 as $row) { $get_sponsor_id_2 = $row['sponsor_id']; $get_plan_id_2 = $row['plan_id']; } if($get_plan_id_2 == $my_plan_id) { echo 'Plan id matches.'; } else { // repeat the process } } } }
