  1. Yeah! I have tried who.is but after some searches, it asks for payment. I need free one.

  2. If you just want the print-r() output (???) then '</td><td> <a href="">' . print_r($value->users, true) . "</a></td></tr>";

  3. From the Laravel documentation: $flight->name = 'Paris to London'; $flight->save(); From your code: $data->image=$request->image; $data->save; Do you see the difference?

  4. Just for fun ... echo ad_decimo('XIIX'); // 18 (used by Roman 18th legion) echo ad_decimo('MCMIL'); // 1949 echo ad_decimo('MCMXLIX'); // 1949 function ad_decimo($str) { $M = 1000; $D = 500; $C = 100; $L = 50; $X = 10; $V = 5; $I = 1; foreach (str_split(strtoupper($str)) as $r) { if (!isset($$r)) return 0; $ra[] = [ 'r' => $r, 'v' => $$r ]; } $d = 0; foreach ($ra as $p => $a) { $d += $a['v'] * subtracto($ra, $p, $a['v']); } return $d; } function subtracto($rarr, $pos, $val) { // is there a higher value letter following this one? for($i=$pos+1, $k=count($rarr); $i<$k; $i++) { if ($rarr[$i]['v'] > $val) return -1; } return 1; }

  6. There is a very easy way to do this using a MySql myisam table. Store each vote in a table like this... CREATE TABLE `vote` ( `username` varchar(50) NOT NULL, `vote_year` year(4) NOT NULL, `week_num` tinyint(4) NOT NULL, `vote_count` int(11) NOT NULL AUTO_INCREMENT, `time_voted` datetime DEFAULT CURRENT_TIMESTAMP, `voted_for` int(11) DEFAULT NULL COMMENT 'Who/whatever was voted for', PRIMARY KEY (`username`,`vote_year`,`week_num`,`vote_count`) ) ENGINE=MyISAM DEFAULT CHARSET=utf8; Note the last column of the primary key is the auto-increment column "vote_count". This will make the vote count start again at 1 for each username each week whe you add votes. mysql> INSERT INTO vote (username, vote_year, week_num, voted_for) VALUES -> ('user1', year(curdate()), weekofyear(curdate()), 1), -> ('user1', year(curdate()), weekofyear(curdate()), 20), -> ('user1', year(curdate()), weekofyear(curdate()), 5), -> ('user2', year(curdate()), weekofyear(curdate()), 5), -> ('user2', year(curdate()), weekofyear(curdate()), 1), -> ('user2', year(curdate()), weekofyear(curdate()), 3); Query OK, 6 rows affected (0.00 sec) mysql> select * from vote; +----------+-----------+----------+------------+---------------------+-----------+ | username | vote_year | week_num | vote_count | time_voted | voted_for | +----------+-----------+----------+------------+---------------------+-----------+ | user1 | 2021 | 24 | 1 | 2021-06-16 17:37:56 | 1 | | user1 | 2021 | 24 | 2 | 2021-06-16 17:37:56 | 20 | | user1 | 2021 | 24 | 3 | 2021-06-16 17:37:56 | 5 | | user2 | 2021 | 24 | 1 | 2021-06-16 17:37:56 | 5 | | user2 | 2021 | 24 | 2 | 2021-06-16 17:37:56 | 1 | | user2 | 2021 | 24 | 3 | 2021-06-16 17:37:56 | 3 | +----------+-----------+----------+------------+---------------------+-----------+ 6 rows in set (0.00 sec) To do the insert in PHP $stmt = $pdo->prepare("INSERT INTO vote (username, vote_year, week_num, voted_for) VALUES ( ?, year(curdate()), weekofyear(curdate()), ? ) "); $stmt->execute( [ $username, $votedFor ] ); Now it doesn't matter how many times a user votes. When you come to counting the votes for each "voted_for" just ignore all records whose vote_count is > 10 SELECT voted_for , count(*) as votes FROM vote WHERE vote_count <= 10 GROUP BY voted_for ORDER BY votes DESC
