I recommend you use numpy arrays for this, that will be the easiest way. Either convert your tuples to arrays or just store them as arrays. If you subtract numpy arrays, they will be subtracted elementwise. The same statement is true for squaring (which, btw, in Python is not ^2 but **2). You will then … Read more
string[] iniArray = { “M Facci”, “D Thornton”, “B Luke”, “S Tofani”, “T Luke” }; var sortedArray = iniArray.OrderBy(r => r.Split(‘ ‘).Last()).ToArray(); or (courtesy @killercam) var sortedArray = iniArray.OrderBy(r => r.Split().Last()).ToArray(); Assuming there is only First Name and Last Name in a string, also, there exists a Last Name.

In your loop, create a new array occurance each iteration. Then use json_encode() to turn that array into a valid JSON string. $json = []; for ($i = 0; $i < (count($getnodays)); $i++) { $json[] = [‘Category’ => $getctgry[$i], ‘Priority’ => $getpriotity[$i], ‘NoOfDays’ => $getnodays[$i], ‘StDate’ => $date1[$i], ‘EdDate’ => $date2[$i], ]; } echo json_encode($json); … Read more
