If your happy enough having just a multi-dimensional array, this should work fine. I had wanted to use the one provided by keananda but it was choking on pr($lines).

<?php
function f_parse_csv($file, $longest, $delimiter) {
  $mdarray = array();
  $file    = fopen($file, "r");
  while ($line = fgetcsv($file, $longest, $delimiter)) {
    array_push($mdarray, $line);
    }
  fclose($file);
  return $mdarray;
  }
?>

$longest is a number that represents the longest line in the csv file as required by fgetcsv().  The page for fgetcsv() said that the longest line could be set to 0 or left out, but I couldn't get it to work without. I just made it extra large when I had to use it.
