Of course it needs to exist: you're trying to use it. Can't very well use something that doesn't exist, can you? But perhaps it's not a "Config" class you need to use?

Barand You are the Best! I know sometimes I run in to an end and the solution is there but just hard to find after staring at the same code for days, you my friend are a great start to my weekend! Best to you. And just so you know I posted this on Stack Overflow and was told that I did not try enough and i should try harder before asking questions. I will speak highly of this form and stick around to see if I can help others as well.

try foreach ($array as $k => $d) { if ($k > 0) { if (strtotime($d) > strtotime($array[$k-1])+6) { $new[] = "-------------------"; } } $new[] = $d; } $new = Array ( [0] => 2021-02-10 09:04:48 [1] => 2021-02-10 09:04:54 [2] => 2021-02-10 09:05:00 [3] => 2021-02-10 09:05:06 [4] => 2021-02-10 09:05:12 [5] => 2021-02-10 09:05:18 [6] => ------------------- [7] => 2021-02-10 09:06:18 [8] => 2021-02-10 09:06:24 ) [edit...] Alternative solution... $new = []; $ne

$this (programming pun intended) is the correct syntax, but produced a different error than the one you posted about the undefined variable. what was the error message in $this case? i'm going to guess that the database connection probably failed and there's no useful error handling in the code. while not the cause of the most immediate problem, your main code should be responsible for creating the database connection, then use dependency injection to supply that to any class that needs it. by making each class responsible for getting a specific database connection, your code is not ge

Define customer/product as UNIQUE... CREATE TABLE `cart` ( `cart_id` int(11) NOT NULL AUTO_INCREMENT, `customerID` int(11) DEFAULT NULL, `productID` varchar(5) DEFAULT NULL, `quantity` int(11) DEFAULT NULL, PRIMARY KEY (`cart_id`), UNIQUE KEY `UNQ_cart_product` (`customerID`,`productID`) ) BEFORE +---------+------------+-----------+----------+ | cart_id | customerID | productID | quantity | +---------+------------+-----------+----------+ | 1 | 1 | ABC12 | 3 | | 2 | 1 | DEF23 | 5 | +---------+------------+-----------+---

TIP: If you are creating home-grown charts, plotting the values is the easy bit. 95% of the coding effort will be in the drawing of chart area, plot area, axes, axis labels, scaling, titles etc. You can sidestep this with a simple table with horizontal bars. EG CODE EXAMPLE... <?php $values = [ 'Strongly Disagree' => 7, 'Disagree' => 10, 'Neither' => 12, 'Agree' => 25, 'Strongly Agree' => 41 ]; function valueChart(&$values) { $ou

If you echo '<pre>$json = ', print_r($json, 1), '</pre>'; you get $json = Array ( [terms] => http://www.xe.com/legal/dfs.php [privacy] => http://www.xe.com/privacy.php [from] => USD [amount] => 1.195 [timestamp] => 2021-02-09T16:52:00Z [to] => Array ( [0] => Array ( [quotecurrency] => NGN [mid] => 454.6559871014 ) ) ) Then follow the array keys to the value you want So you need echo $json['to'][0]['mid']
