I'd take the easy way out and use the database with a single query DATA TABLE : season; TABLE : price +-----------+----------------+------------+------------+--------+ +----+--------+------+-------+ | season_id | name | start_date | end_date | tariff | | id | tariff | day | price | +-----------+----------------+------------+------------+--------+ +----+--------+------+-------+ | 1 | Winter 2024 | 2024-11-01 | 2024-12-23 | LO | | 1 | ST | 0 | 70 | day 0 = Monday | 2 | Christmas 2024 | 2024-12-24 | 2025-01-02 | PK | | 2 | ST | 1 | 70 | | 3 | Easter 2025 | 2025-04-11 | 2025-04-27 | PK | | 3 | ST | 2 | 70 | | 4 | Summer 2025 | 2025-06-15 | 2025-08-31 | HI | | 4 | ST | 3 | 70 | +-----------+----------------+------------+------------+--------+ | 5 | ST | 4 | 90 | | 6 | ST | 5 | 90 | | 7 | ST | 6 | 70 | day 6 = Sunday TABLE : tariff | 8 | LO | 0 | 55 | +--------+-------------+ | 9 | LO | 1 | 55 | | tariff | description | | 10 | LO | 2 | 55 | +--------+-------------+ | 11 | LO | 3 | 55 | | HI | High season | | 12 | LO | 4 | 75 | | LO | Low season | | 13 | LO | 5 | 75 | | PK | Peak season | | 14 | LO | 6 | 55 | | ST | Standard | | 15 | HI | 0 | 90 | +--------+-------------+ | 16 | HI | 1 | 90 | | 17 | HI | 2 | 90 | TABLE : booking | 18 | HI | 3 | 90 | +----+------------+---------+------------+ | 19 | HI | 4 | 110 | | id | booking_no | room_no | book_date | | 20 | HI | 5 | 110 | +----+------------+---------+------------+ | 21 | HI | 6 | 90 | | 1 | 1 | 1 | 2025-05-07 | | 22 | PK | 0 | 110 | | 2 | 1 | 1 | 2025-05-08 | | 23 | PK | 1 | 110 | | 3 | 1 | 1 | 2025-05-09 | | 24 | PK | 2 | 110 | | 4 | 2 | 5 | 2025-04-25 | | 25 | PK | 3 | 110 | | 5 | 2 | 5 | 2025-04-26 | | 26 | PK | 4 | 125 | | 6 | 2 | 5 | 2025-04-27 | | 27 | PK | 5 | 125 | | 7 | 2 | 5 | 2025-04-28 | | 28 | PK | 6 | 110 | | 8 | 2 | 5 | 2025-04-29 | +----+--------+------+-------+ | 9 | 2 | 5 | 2025-04-30 | +----+------------+---------+------------+ QUERY SELECT b.booking_no , MIN(b.book_date) as `from` , MAX(b.book_date) as until , SUM(p.price) as total FROM booking b LEFT JOIN season s ON b.book_date between s.start_date AND s.end_date LEFT JOIN price p ON coalesce(s.tariff, 'ST') = p.tariff -- tariff defaults to "ST" if no seasons match date AND p.day = weekday(b.book_date) GROUP BY b.booking_no; +------------+------------+------------+-------+ | booking_no | from | until | total | +------------+------------+------------+-------+ | 1 | 2025-05-07 | 2025-05-09 | 230 | | 2 | 2025-04-25 | 2025-04-30 | 570 | +------------+------------+------------+-------+

<?php $images = glob("path/to/folder a/*.*"); foreach ($images as $i) { echo "<img src='$i'>"; }

The DATEDIFF() function will give the difference in days. Use TIMESTAMPDIFF() which lets you the specify the units for the result. mysql> SELECT NOW(), timestampdiff(SECOND, '2025-04-26 20:30:00', NOW()) as diff; +---------------------+------+ | NOW() | diff | +---------------------+------+ | 2025-04-26 21:34:51 | 3891 | +---------------------+------+ 1 row in set (0.00 sec) mysql> SELECT NOW(), timestampdiff(MINUTE, '2025-04-26 20:30:00', NOW()) as diff; +---------------------+------+ | NOW() | diff | +---------------------+------+ | 2025-04-26 21:35:22 | 65 | +---------------------+------+ 1 row in set (0.00 sec)

If the only reason for that value is to write to the DB then you can do it in the insert query... INSERT INTO tablename (colx, coly, colz) VALUES (?, ?, NOW() + INTERVAL 10 MINUTE)

Put icon insisde a link EG... <a href='https://facebook.com'> <i class="fa-brands fa-facebook w3-hover-opacity"></i> </a>

INSERT INTO `Bank_Reason` (`ID`, `ReasonID`, `Reason`,`Colour`) VALUES (1, 0, '---SELECT','#000000'), (2, 1, 'Other',','#0000ff'), ^^ Again!?

INSERT INTO `Bank_Reason` (`ID`, `ReasonID`, `Reason`,Colour') VALUES ^ | unwanted single quote

$surname_counts = array_count_values(array_map(fn($v)=>substr($v, strpos($v, '_', 0)+1), $names)); -> Array ( [jones] => 2 [smith] => 3 [doe] => 2 [jackson] => 1 )

Put this line just before the mysqli connection code... mysqli_report(MYSQLI_REPORT_ERROR|MYSQLI_REPORT_STRICT); Ensure error_reporting is ON. You should now get error messages if there are problems with a query.

PS You aren't doing yourself any favours by insisting on mysqli. PDO is a superior library and easier to use. While you are still learning, put your effort into PDO

Change $pdo = pdoConnect(); to $pdo = new mysqli(HOST, USERNAME, PASSWORD, DATABASE); Job done.

BTW, it seems a pity that that those students who attain a C6 grade should receive only an anagram instead of a Credit

@sule, Here are two version of the program A single loop tracking changes in studentid (as I suggested) Stores data in a muti-dimensional array and uses nested foreach() loops Version 1 <?php define("HOST", 'localhost');

I've just described a method to you. What have you now tried? (or are you just going to keep repeating the same question without trying the suggestion?)
