[A previous version of this function which I wrote] did not parse empty cells at the end of a line
correctly. Here's the fixed version. Thanks to Graham Lawrence for the
fix. <?php function
parse_csv($file,$comma=',',$quote='"',$newline="\\n")
{ $db_quote = $quote . $quote;
// Clean up file $file = trim($file); $file =
str_replace("\\r\\n",$newline,$file);
$file = str_replace($db_quote,'"',$file); // replace double quotes with
" HTML entities $file =
str_replace(',",',',,',$file); // handle
,"", empty cells
correctly 						$file =
str_replace(","\\n",",\\n",$file); // handle
,""\\n empty cells correctly at the end of lines
$file .= $comma; // Put a comma on the end, so we parse last cell
$inquotes =
false; $start_point = 0; $row = 0;
$cellNo = 0; for($i=0; $i<strlen($file);
$i++) { $char = $file[$i];
if ($char == $quote) { if ($inquotes) {
$inquotes = false; }
else { $inquotes = true;
} } if
(($char == $comma or $char == $newline) and !$inquotes) { $cell =
substr($file,$start_point,$i-$start_point); $cell =
str_replace($quote,'',$cell); // Remove delimiter quotes
$cell = str_replace('"',$quote,$cell); // Add in data
quotes if ($row>0) $data[$row][$data[0][$cellNo]] =
$cell; else $data[$row][] = $cell;
