[ad_1] You can do this using groupBy and map functions of Laravel’s Collection: $collection = new \Illuminate\Support\Collection($array); $group = $collection->groupBy(‘product_id’); $resultArray = $group->map(function($item, $key) { return [ ‘total_size’ => $item->sum(‘comp_size’), ‘product_id’ => $key, ]; }); This will let you expand the code a bit easier in the future. 1 [ad_2] solved Sum array values of … Read more

[ad_1] Your function decodeWebStream mutates the input variable d. This probably combined with an error elsewhere in your code double-encoding your data is probably leading to the second call of decodeWebStream giving you the correct value (but not first or third). 1 [ad_2] solved Node.js bug ? function’s return value change when stored as variable
[ad_1] Without a MCVE and actual requirements on which image you want from the images table and a better understanding of why you need a left join when your where clause makes it behave like an inner… and why the where clause is so complex… …I’m really unsure what the question is after… Here’s a … Read more
[ad_1] Sounds like there are two parts to this question: 1. Getting an image from a video I suppose you manage to do this since you did not provide any info on the video file format. 2. Detecting a QR code in an image. Multiple options exist: Use the AForgeTry using AForge.NET library for capturing … Read more
[ad_1] You can parse the json to an object: var obj = JSON.parse(text); and then retrieve the values from the object: obj[“1”][0].RequestId if you want to display them all, you need to iterate through the array and print the values you want: for (var i = 0; i<output.length; i++) { $(“#YOURDIV”).append(“Request id: ” + obj[i][0].RequestId); … Read more
[ad_1] Read more about C++11 at least (or C++14 or C++17), e.g. some good C++ programming book (any standard older than C++11 is obsolete, and C++11 has evolved a lot since its predecessors, so you should almost consider C++11 as a new programming language). Look also some C++ reference site. [](const string &left, const string … Read more
[ad_1] The following UPDATE statement will guarantee that each row has a unique MY_TIMESTAMP value, by increasing the milliseconds by the rownum value. EDIT: After Alessandro Rossi pointed out that there could be duplicate values, the following query has been modified to use SYSTIMESTAMP for the update. UPDATE ITEM_HISTORY SET my_timestamp = SYSTIMESTAMP + NUMTODSINTERVAL(rownum/1000, … Read more
[ad_1] This sounds like a task for regular expression. In C++ there is support for regex especially regex_match. I guess, this should get you started. But be warned, what you are trying to accomplish will not be solved by simple regex. Your matching string might look something like this /\/function name: ([^\\]*).*/ This will look … Read more
[ad_1] You can use the where_in method as a shortcut to multiple or-statements for the same column: $available_ids = [1, 2, 3]; $this->db->where_in(‘id’, $available_ids); // WHERE id IN (1, 2, 3) If you were looking to check multiple columns (the name is ‘Adam’ or the title is ‘Grand Poobah’ or the status is ‘Active’), you … Read more
[ad_1] It’s because when you enter a number and press Enter key, scan.nextInt() consumes only the entered number, not the “end of line”. When scan.nextLine() executes, it consumes the “end of line” still in the buffer from the first input which you have provided during the execution of scan.nextInt() . Instead, use scan.nextLine() immediately after … Read more
[ad_1] The effect is as you write, but it’s achieved using a slightly different sequence: The post-increment has highest precedence, so it’s evaluated first. However, its return value (which is processed by further operators) is the value of iter before the increment. Dereference is evaluated next, returning pointer to which the non-incremented value of iter … Read more
