php - csv file requires to open and save again in order to display data. -


i exporting csv file server , using php script fetch data csv , show on webpage.

now it's working good.

but problem have open exported csv file first , copy paste date csv file.

it not fetching data exported file straight away.

it's weird, said when copy data , provide same name csv file, same, works.

why that.

php function(although don't think there problem that)

    public function import(){       $fp = fopen(data_path.'/testfile.csv', 'r');      // first (header) line     $header = fgetcsv($fp);      // rest of rows     $data = array();     while ($row = fgetcsv($fp)) {       $arr = array();       foreach ($header $i => $col)         $arr[$col] = $row[$i];       $data[] = $arr;     }        $all = $data;      $soldval=array();     foreach ($all $key=>$value){         $sold = $value["total_qty_ordered"];         array_push($soldval, $sold);     }      print_r($soldval);     //echo '<br/>';     $totalseats = intval('1000');     $prodtotal = intval(array_sum($soldval));     $totalleft = $totalseats-$prodtotal;      return       'products sold '.$prodtotal;             //.' seats left '.$totalleft;  }
