You use $result for the result of the first query and then use that same variable again inside the loop. Another reason not to be calling queries inside loops. As I said, get rid of that first query and replace it with the second, and just process those results. Are you running on a live host?

Those files are not particularly large, so I am baffled by that MAX_JOIN_SIZE error. The default is 18,446,744,073,709,551,615 which is a few more more than 1,352,000,000 (the cartesian product of your query, which is the number of rows returned if every record in the tables was joined with every record in the other tables ie 20000 x 260 x 260). Did you get an error message for that first query?

try foreach ($Arr['scan_results']['scan_details']['F-prot'] as $k => $v) { echo "$k : $v <br>"; }

Change die ("Cant do it!"); to die ($cnx->error); Then we can see why the first query is failing. You should not be running that first query any more. I said you should NOT run queries inside loops and you are still doing it. You should just be running the one combined query and process it's results. EDIT : How many rows in your tables?

can you alter your code to this $Arr = json_decode($FileScanner, true); echo '<pre>' . print_r($Arr, true) . '</pre>'; That should make it easier to read.

Those errors are not from $cxn_>error. Where you had or die("no can do"); change to or die($cxn->error); Is that simple enough?

you were supposed be outputting $cxn_error instead of "no can do"

try outputting a meaningful, helpful message, like $cxn->error

Don't run queries inside loops - it eats server resources. Combine the two queries into one. SELECT d.Latitude AS departure_lat , d.Longitude AS depatrure_lng , a.Latitude AS arrival_lat , a.Longitude AS arrival_lng FROM rosters INNER JOIN airport a ON a.IATA = rosters.Arr INNER JOIN airport d ON d.IATA = rosters.Dep WHERE rosters.Arr = 'CRL' AND rosters.Dep = 'BGY'; AND Code = '$Code' AND SectorDate >= '$today' ORDER BY RostersID

There is no direct equivalent of mysql_result(), which was inefficient anyway. You would fetch the row then reference that to get the data $row = mysqli_fetch_row($age); echo $row[0]; Bad idea to have your age variable and your query result both with the same "$age".

try SELECT d.Latitude AS departure_lat , d.Longitude AS depatrure_lng , a.Latitude AS arrival_lat , a.Longitude AS arrival_lng FROM rosters INNER JOIN airport a ON a.IATA = rosters.Arr INNER JOIN airport d ON d.IATA = rosters.Dep WHERE rosters.Arr = 'CRL' AND rosters.Dep = 'BGY'

You cannot mix mysql_ and mysqli_ functions, Use just mysqli_ library.

Disregard my last post, I understand your data array structure now.

this will convert your existing $colors array to a simple indexed array ($newcolors) $newcolors = array(); foreach ($colors as $color) { $newcolors[] = str_replace(' ', '', $color['color']); }

You started out acknowledging there was a problem with your current structure so I gave you a solution. Now you say you want to stick with that crap. problematic design and get someone to bail you out. Perhaps someone else will.

From what you have described you would want four tables (see attached model) video tag video_tag (to store the tags for each video) click (to log each click of a video's tag)

That's an interesting list of optional solutions but, having read it three times, I still no no idea of what you are trying to achieve. What are you trying to do?

I'd use a multiple insert query and batch in 1,000 rows at a time. EG INSERT INTO tablename (col1, col2, col3) VALUES (1, 2, 'aaa'), (2, 2, 'bbb'), (3, 2, 'ccc'), (4, 3, 'ccc'), (5, 4, 'aaa'), . . . (1000, 1, 'xyz');

Good luck with that request. I asked for information 9 days ago but was totally ignored.

Supposing you have, this (where you said some could be empty) $_POST['item_meta'][124] = 'aaa'; $_POST['item_meta'][125] = 'bbb'; $_POST['item_meta'][126] = 'ccc'; $_POST['item_meta'][127] = 'ddd'; $_POST['item_meta'][128] = 'eee'; $_POST['item_meta'][129] = ''; $_POST['item_meta'][130] = 'fff'; $_POST['item_meta'][131] = ''; $_POST['item_meta'][132] = ''; $_POST['item_meta'][133] = 'ggg'; then to get the $meta_value, all you need is $meta_value = join(',', array_filter($_POST['item_meta'])); to check echo $meta_value; //--> aaa,bbb,ccc,ddd,eee,fff,ggg

try UPDATE ballot INNER JOIN ( SELECT username , COUNT(neptune) as ncount FROM ballot GROUP BY username HAVING ncount > 5 ) n USING (username) SET morethan5 = 'yes' However, it is bad practice to store derived data like that in a db table.

Put "yes" inside single quotes so SQL knows it is a string literal and not a column name ... set morethan5 = 'yes' ...

You can easily get the time diff while you query the data. It looks, from your code, like you store the time as an integer unix timestamp. It is much better to us DATETIME type columns (yyyy-mm-dd hh:ii:ss) so you don't have to convert them every time you use them, plus you can read them. Here's an example of getting the time diff in hours from a unix timestamp SELECT thetime as unixtime , FROM_UNIXTIME(thetime) as realtime , NOW() as timenow , timestampdiff(HOUR, FROM_UNIXTIME(thetime)+INTERVAL 10 HOUR, NOW()) as diff FROM test_time; +------------+---------------------+---------------------+------+ | unixtime | realtime | timenow | diff | +------------+---------------------+---------------------+------+ | 1453276800 | 2016-01-20 08:00:00 | 2016-01-20 09:48:25 | -8 | | 1453284000 | 2016-01-20 10:00:00 | 2016-01-20 09:48:25 | -10 | +------------+---------------------+---------------------+------+ 2 rows in set (0.00 sec)

date_diff() takes two DateTime objects as parameters and returns a DateInterval object http://uk1.php.net/manual/en/datetime.diff.php
