{
if (PHP_VERSION < 6) {
$theValue = get_magic_quotes_gpc() ? stripslashes($theValue) : $theValue;
}
$theValue = function_exists("mysql_real_escape_string") ? mysql_real_escape_string($theValue) : mysql_escape_string($theValue);
switch ($theType) {
case "text":
$theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
break;
case "long":
case "int":
$theValue = ($theValue != "") ? intval($theValue) : "NULL";
break;
case "double":
$theValue = ($theValue != "") ? doubleval($theValue) : "NULL";
break;
case "date":
$theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
break;
case "defined":
$theValue = ($theValue != "") ? $theDefinedValue : $theNotDefinedValue;

// output headers so that the file is downloaded rather than displayed
header('Content-Type: text/csv; charset=utf-8');
header('Content-Disposition: attachment; filename=BOP.csv');
// create a file pointer connected to the output stream
$output = fopen('php://output', 'w');
// output the column headings
fputcsv($output, array('ID','Common Name', 'Scientific Name', 'Breeds', 'Abundance', 'Occurrence', 'Seasonal Status','AOU_Order '));
// fetch the data
mysql_select_db($database_PaSiteGuide, $PaSiteGuide);
$rows = mysql_query('SELECT BirdsOfPa.ID, BirdsOfPa.CommonName, BirdsOfPa.SciName, BirdsOfPa.Breeding, BirdsOfPa.Abundance, BirdsOfPa.Occurrence, BirdsOfPa.SeasonalStatus, AOU_List.AOU_Order FROM BirdsOfPa, AOU_List WHERE BirdsOfPa.ID = AOU_List.SPNO ORDER BY AOU_List.AOU_Order ASC');
// loop over the rows, outputting them
while ($row = mysql_fetch_assoc($rows)) fputcsv($output, $row);
?>
?>
