I've written this to handle :
- fields with or without enclosure;
- escape and enclosure characters using the same character (ie <<">> in Excel)

function csvToArray($fileContent,$escape = '\\', $enclosure =

{

$fields = array();
if($escape == $enclosure)

$nb = strlen($fileContent);
$field = '';
$inEnclosure = false;

for($i = 0;$i<$nb; $i++)
