I don't see why it was printing all those \n's.

mySQL is the ideal solution. It's much faster than flat files.

I would, but then that would happen. I might just have to use MySQL instead =\ I really wanted to use flat files, and it's not working ><

hmm, take out that \n then

And the resulting outcome: http://www.eracreations.com/sourceviewer_101.php?file=/members/necrotic/ratios.dat ... wow

EDIT: I see what it's doing. It's added a new line for every time the script is run. So if I run it ten times, there will be 10 lines between each number.

I'm sorry, that should be $dat_file.

and to fix the formatting problem, change fwrite() to:
fwrite($fp, "$shown\n")

I was looking at your code. Where'd you get $file from? It's not anywhere in your code or mine. Is it supposed to be $fp?

Your ratios file isn't that large, so you could try sucking it into an array right off the bat. Then just increment the one number, and write the whole array to the file again.

<?php
function SetRatio() {
  global $random,$filename;
  if (is_writable($filename)) {
    $dat_file = file($filename);
    
    $fp = fopen($filename, 'w');
    if (!$fp) {
      print \"Cannot open file ($filename)\";
      exit;
    }
    else {
      
      $max = (count($file)>$random) ? count($file) : $random;
      
      for ($id=1; $id<=$max; $id++) {
        if ($id<=count($file)) {
          $shown = $file[$id];
        }
        else {
          $shown = 0;
        }
        
        if ($id == $random) {
          $sid = $id;
          $shown = $shown+1;
        }
        
        if (!fwrite($fp, $shown)) {
          print \"Error writting to ($filename) on line ($id)<br>\";
          exit;
        }
      }
      
      fclose($fp);
    }
  }
  else {
    print \"The file $filename is not writable\";
  }
}
?>

Oops, sorry. I guess I missed this thread.

I'm wondering if it's having problems writting to the same file handle it's reading from. Try this:

<?php
function SetRatio() {
  global $random,$filename;
  if (is_writable($filename)) {
    $fp1 = fopen($filename, 'r+');
    $fp2 = fopen($filename, 'w+');
    if (!$fp1 || !$fp2) {
      print \"Cannot open file ($filename)\";
      exit;
    }
    else {
      
      for ($id=1; $id<=$random; $id++) {
        if ($ratios = fscanf($fp1, \"%s\n\")) {
          list($shown) = $ratios;
        }
        else {
          $shown = 0;
        }
        
        if ($id == $random) {
          $sid = $id;
          $shown = $shown+1;
          if (!fwrite($fp2, $shown)) {
            print \"Error writting to ($filename) on line ($id)<br>\";
            exit;
          }
        }
        else {
          if (!fwrite($fp2, $shown)) {
            print \"Error writting to ($filename) on line ($id)<br>\";
            exit;
          }
        }
      }
      
      // copy the rest of file 1 to file 2
      while ($ratios = fscanf($fp1, \"%s\n\")) {
        list($shown) = $ratios;
        if (!fwrite($fp2, $shown)) {
          print \"Error writting to ($filename) on line ($id)<br>\";
          exit;
        }
        $id++;
      }
      
      fclose($fp1);
      fclose($fp2);
    }
  }
  else {
    print \"The file $filename is not writable\";
  }
}
?>

Mark, as I posted above, your changes didn't work
