$firstPassComplete = (isset($firstPassComplete)) ? true:false;
foreach ($row as $k => $v) {
if (!$firstPassComplete){
//get keys only on the first pass through array since it is repeated for every row
$keys[] = is_string($k) ? '"' . str_replace('"', '""', $k) . '"' : $k;
}
$values[] = is_string($v) ? '"' . str_replace('"', '""', $v) . '"' : $v;
}
if (count($keys) > 0) echo implode($delimiter, $keys) . $linebreak;
if (count($values) > 0) echo implode($delimiter, $values) . $linebreak;
}
}, 200, array_merge(array(
