Say I have a records table with multiple records. There could be multiple records with the same name but different amounts. For Eg. Looking at the table below, the results should retrieve newest record-1 and record-2 because their amount is equals to or greater than 5.00. Record-3 is not selected because it falls below 3.00. record_id record_name record_amount 1 record-1 4.00 2 record-1 3.00 3 record-2 2.00 4 record-1 5.00 5 record-2 6.00 6 record-3 3.00 $get_records = $db->prepare("SELECT record_id, record_name FROM records WHERE record_amount >= :record_amount ORDER BY record_id DESC"); $get_records->bindValue(':record_amount', 5.00); $get_records->execute(); $result_records = $get_records->fetchAll(PDO::FETCH_ASSOC); if(count($result_records) > 0) { foreach($result_records as row) { $record_id = $row['record_id']; $record_name = $row['record_name']; echo $record_name; } } Currently the query above outputs ALL the rows that matches the >=. What I want to do is select only ONE row of each unique record name that matches the criteria. And that row is typically the last row that was inserted. So the output would be like only these two. How do I do that? 4 record-1 5.00 5 record-2 6.00

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 asked this question before and I did receive the answer I was looking for. But now I realize something. It only works for the first result. Let me explain. I am using this API. https://block.io/api/simple/php $get_address = $block_io->get_transactions(array('type' => 'received', 'addresses' => $my_wallet)); $api_amount = $get_address->data->txs[0]->amounts_received[0]->amount; $api_recp = $get_address->data->txs[0]->amounts_received[0]->recipient; $api_trans_id = $get_address->data->txs[0]->txid; $api_sender_id = $get_address->data->txs[0]->senders; These are variables above i am using to check if something is true or not. For eg. The form below. I want to check if the $api_trans_id matches the the post id I submit below. if($api_trans_id == $_POST['trans-id']) { echo 'Success'; } else { echo 'Fail.'; } <form action="" method="post"> <input type="text" name="trans-id" value="" maxlength="1084" /> <input type="submit" name="submit" value="Submit" /> </form> The above works if the first result in the json array below has the same post id or else it fails. I want to loop through ALL the json arrays and try to match the post id($_POST['trans-id']). Below are the 3 array results to give you an example. The first txid is "41d9afcc73da63c45674088411460116cfefe324cc7a6f5fcb267d9f584adf73". If I submit this same id as the post id in the form, it'll be success full. But if I use the 2nd or 3rd txid below, it will fail. So how can I change this "$api_trans_id = $get_address->data->txs[0]->txid;" so that it looks for all three txid instead of only the first one? { "status" : "success", "data" : { "network" : "BTC", "txs" : [ { "txid" : "41d9afcc73da63c45674088411460116cfefe324cc7a6f5fcb267d9f584adf73", "from_green_address" : false, "time" : 1496877627, "confirmations" : 3080, "amounts_received" : [ { "recipient" : "1QFaAYB4r8sk7MG3beb7yY4R21t9JrnMwK", "amount" : "0.00200000" } ], "senders" : [ "2EqvPUTwjUuon6c2a6YxBreJtBkkZD5fsp" ], "confidence" : 1.0, "propagated_by_nodes" : null }, { "txid" : "2f72d4dd97234937ddf6e8174b17a9a421ba35bbfb6fa40cfeb6ac92db6ce032", "from_green_address" : false, "time" : 1491675979, "confirmations" : 12338, "amounts_received" : [ { "recipient" : "1QFaAYB4r8sk7MG3beb7yY4R21t9JrnMwK", "amount" : "0.00010000" } ], "senders" : [ "3L98MQZKvwNo21fFpY7RJ9HYfYdv62XpYz" ], "confidence" : 1.0, "propagated_by_nodes" : null }, { "txid" : "fce58f0cb1d32c1ed7c27825c41753ce98323771bd931f0a0f99b6294d9ee642", "from_green_address" : false, "time" : 1491672301, "confirmations" : 12341, "amounts_received" : [ { "recipient" : "1QFaAYB4r8sk7MG3beb7yY4R21t9JrnMwK", "amount" : "0.00010000" } ], "senders" : [ "4L98MQZKvwNo21fFpY7RJ9HYfYdv62XpYz" ], "confidence" : 1.0, "propagated_by_nodes" : null }, ] } }
