Question

I have to run a pairing algorithm for a game and when the pairing is done, I display the pairing on HTML and create a csv file as well. Right now, once I am done with pairing, I create a multidimensional array to store the specific value and then pass it to the function in same php file to generate the csv file. However, doing this outputs the entire page code i.e. html and php code to the .csv file. Here is the code:

   function performPairing()
   {
       .... 
      $count=0;
      $resultArray[][] = array();
      while ($currrow = @mysql_fetch_row($result))
      {
         $playerone = $currrow;
         $playertwo = @mysql_fetch_row($result);
         $resultArray[$count][] = $playerone[1];
         $resultArray[$count][] = $playerone[0];
         $resultArray[$count][] = $playertwo[1];
         $resultArray[$count][] = $playertwo[0];
         $count++;
         updateforeachrow($playerone, $playertwo);
      }
      generateDocument($resultArray, $count);
   }

    function generateDocument($resultArray, $count)
    {
        $output = fopen('php://temp/maxmemory'.(5*1024*1024), 'r+');
        $columns = array('Player One Col1', 'Player One Col2', 'Player Two Col1', 'Player Two Col2');
        fputcsv($output, $columns);
         for ($index=0 ; $index <=$count; $index++)
         {
            fputcsv($output, $resultArray[$index]);
         }
        rewind($output);
        $export = stream_get_contents($output);
        fclose($output);
        header('Content-type: application/octet-stream');
        header('Content-Disposition: attachment; filename = "export.csv"');
        echo $export;  
} 

However doing this outputs the entire html code to csv rather than specific rows. Can anyone please help me on this?

Answer 1

. make string
. output string to file
. send header with (is this allowed this way?)

use file_put_contents ( filename, str ), and than send it with headers.
Make code simpler 🙂
