[RESOLVED] multidimensional csv linking - no idea?!

[LingoOutsider]

I have a spreadsheet that I can view with the power of PHP!...

<?PHP
 
   $file_handle = fopen("library.csv", "r");
   
  while (!feof($file_handle) ) {
 
   $text = fgetcsv($file_handle, 1024);
 
   print $text[1] . " . " . $text[2] . "<BR>";
  }
 
   fclose($file_handle);
 
?>

But what i really what to do is sort the information dependant on what the user selects.

My first column has "authers" (most repeated) If one auther is selected i want column two to only show books by that auther.

So can I create a link (mousedown varable) with a slice of information from a csv file?

And can I switch on/off rows in a csv file?

Thank for any help or direction!
