Store part of array when array_search is successful
Barand replied to mongoose00318's topic in PHP Coding Help
That isn't the most comprehensive requirements specification that I have worked from so there is a bit of guesswork involved, such as the comparison criteria being job number and line item matching, and which columns are to be updated from the csv data. If this is the case, your "production_data" table should have an index on these columns (as my temp table below has). Anyway, given those caveats, the processing would be along the lines below (4 queries instead of 40,000) and should give you a guide. <?php ## ## This initial section would normally be in an included file ## const HOST = 'localhost'; const USERNAME = '???'; const PASSWORD = '???'; const DATABASE = '???'; function pdoConnect($dbname=DATABASE) { $db = new PDO("mysql:host=".HOST.";dbname=$dbname;charset=utf8",USERNAME,PASSWORD); $db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); $db->setAttribute(PDO::ATTR_DEFAULT_FETCH_MODE, PDO::FETCH_ASSOC); $db->setAttribute(PDO::ATTR_EMULATE_PREPARES, false); $db->setAttribute(PDO::MYSQL_ATTR_LOCAL_INFILE, true); return $db; } ## ## Connect to DB server ## $db = pdoConnect(); ## ## create a temporary table to store the csv data ## $db->exec("CREATE TEMPORARY TABLE production_csv ( id int not null auto_increment primary key, enterprise tinytext, part_num text, description text, qty int, line_item varchar(11), job_num int, work_order varchar(50), psm varchar(50), date_change_flag tinyint, scheduled_ship_date date, on_hold tinyint, on_hold_reason varchar(50), total_hours decimal(10,2), worfc varchar(50), INDEX job_line (job_num, line_item) )"); ## ## load the csv data into the table ## $db->exec("LOAD DATA LOCAL INFILE 'prod_data.csv' INTO TABLE production_csv FIELDS TERMINATED BY ',' LINES TERMINATED BY '\n' IGNORE 1 LINES (@dummy, @dummy, enterprise, part_num, desc, qty, line_item, job_num, work_order, psm, date_change_flag, scheduled_ship_date, on_hold, on_hold_reason, total_hours, worfc) "); ## ## write matching production_data records to archive ## $db->exec("INSERT INTO production_archive SELECT pd.* FROM production_data pd JOIN production_csv USING (job_num, line_item) "); ## ## update the production_data table from the production_csv table ## $db->exec("UPDATE production_data d JOIN production_csv c USING (job_num, line_item) SET d.enterprise = c.enterprise, d.part_number = c.part_num, d.description = c.description, d.qty = c.qty, d.as400_ship_date = c.scheduled_ship_date, d.hold_status = c.on_hold ") ?> -
Store part of array when array_search is successful
Barand replied to mongoose00318's topic in PHP Coding Help
Show us the table structure/s you are working with and the csv layout. Tell us precisely what the goal is and let's see if we can come up with a more efficient way than 40,000 queries. -
Store part of array when array_search is successful
Barand replied to mongoose00318's topic in PHP Coding Help
Databases were designed for matching and searching. Any particular reason why you pull data from the DB then do the searching? That is not the way to use key() array_search returns the key of the found item, not a count. -
I'd do something like this $data = json_decode($j, 1); foreach ($data['results'][0]['address_components'] as $address) { if (in_array('sublocality', $address['types'])) { echo "Sublocality : {$address['long_name']}<br>"; } if (in_array('administrative_area_level_1', $address['types'])) { echo "Administrative area level 1 : {$address['long_name']}<br>"; } }

Here's one way <?php $n = 1; for ($i=0; $i<12; $i++) { printf("%15d | %-20s\n", $n, weird_format($n)); $n *= 10; } function weird_format($n) { if (($k = strlen($n)) < 4) return $n; $a = substr($n, 0, $k-3); // split off the last 3 chara $b = substr($n, -3); if (!($k%2)) $a = ' '.$a; // ensure first section is even no of chars $c = str_split($a, 2); // split into groups of 2 return trim(join(',', $c) . ',' . $b); // join them with commas } ?> Output: 1 | 1 10 | 10 100 | 100 1000 | 1,000 10000 | 10,000 100000 | 1,00,000 1000000 | 10,00,000 10000000 | 1,00,00,000 100000000 | 10,00,00,000 1000000000 | 1,00,00,00,000 10000000000 | 10,00,00,00,000 100000000000 | 1,00,00,00,00,000

Of course it does - as already stated, inet_aton() is an SQL function not PHP

$stmt = $pdo->prepare("UPDATE `download` SET `ip_address` = inet_aton(`ADDRESS`) WHERE ip_address is null;"); @gw1500se Those look like backticks to me

Selecting records without relations in another table
Barand replied to Strahan's topic in MySQL Help
Simple rule: if you are LEFT JOINing to a table, put any conditions on that table in the ON clause. (If you put them in the WHERE clause, the join behaves as an INNER JOIN) -
Don't run queries in side loops. Use a single query which joins the two tables. Use prepared statements. Use PDO, it's easier and better than mysqli. You could use a second query to group/sum the product totals but as you are listing all the products anyway, you may as well total them into an array as you go. <?php // assumes you have a PDO conection here $tdata = ''; $totdata = ''; $date_from = $_POST['date1'] ?? date('Y-m-d', strtotime('first day of this month')); $date_to = $_POST['date2'] ?? date('Y-m-d'); $res = $db->prepare("SELECT o.order_id , CONCAT(o.firstname, ' ', o.lastname) as full_name , DATE_FORMAT(o.date_added, '%M %e, %Y') as date , p.name as product , p.quantity as qty FROM oc_order o JOIN oc_order_product p USING (order_id) WHERE o.order_status_id <> 0 AND o.date_added BETWEEN ? AND ? ORDER BY o.order_id, product "); $res->execute( [ $date_from, $date_to ] ); $prevorder = 0; $totals = []; foreach ($res as $r) { if ($r['order_id'] != $prevorder) { $tdata .= "<tr><td>{$r['full_name']}</td><td>{$r['date']}</td><td colspan='2'> </td></tr>"; $prevorder = $r['order_id']; } $tdata .= "<tr><td colspan='2'> </td><td>{$r['product']}</td><td>{$r['qty']}</td></tr>"; // accumulate totals by product if (isset($totals[$r['product']])) { $totals[$r['product']] += $r['qty']; } else { $totals[$r['product']] = $r['qty']; } } arsort($totals); foreach ($totals as $p => $q) { $totdata .= "<tr><td>$p</td><td>$q</td></tr>"; } ?> <!DOCTYPE html> <html lang="en"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <title>Example</title> <style type="text/css"> table {width: 50%; margin: 16px 50px; border-collapse: collapse; } th {background-color: #000; color: #FFF; padding: 8px;} td {padding: 4px 8px;} </style> </head> <body> <h3>Orders</h3> <table> <tr><th>Customer</th><th>Date</th><th>Product</th><th>Quantity</th></tr> <?=$tdata?> </table> <h3>Product Totals</h3> <table> <tr><th>Product</th><th>Total Qty</th></tr> <?=$totdata?> </table> </body> </html> Giving Your data needs nomalizing.

Fatal error: Allowed memory size of bytes exhausted
Barand replied to TrueMember's topic in PHP Coding Help
A common cause of memory exhaustion is infinite recursion. Are you sure about that callback? -
try SELECT DISTINCT u.firstname , u.lastname FROM ssm_chat_link a JOIN ssm_chat_link b USING (chat_id) JOIN user u ON a.user_id = u.user_id WHERE b.user_id = 1;

As a compromise, when you add a download record, get the id of the matching ip_lookup record and store that in the download record. That way you aren't duplicating the contry/area/city data and you get extremely efficient joins. SELECT download.FILENAME , ip_lookup.country , ip_lookup.area , ip_lookup.city FROM download INNER JOIN ip_lookup ON download.ip_id = ip_lookup.id WHERE download.FILENAME is not null

convert unsigned int ip_address from db to string
Barand replied to larry29936's topic in PHP Coding Help
Were they originally saved using INET_ATON to convert from "w.x.y.z" to an integer? -
Without knowing what output you are expecting from that input, how can we say what's missing? The inputs are dodgy too. Each sub2 will overwrite the previous one, leaving you with 2-92 and 3-90 only.
