[ad_1] First of all, you should redesign your data structure. You aggregate the values in strings in $values and then it’s difficult to extract and use the individual components. $values = array(); for($i=1;$i<=$arrayCount;$i++){ $date = trim($allDataInSheet[$i][“A”]); $dir = trim($allDataInSheet[$i][“B”]); $sinvalue= sin(deg2rad($dir)); $cosvalue= cos(deg2rad($dir)); $values[] = array( ‘date’ => $date, ‘sin’ => $sinvalue, ‘cos’ => $cosvalue, … Read more
