我最终在Experts-exchange上得到了答案.这是有效的方法:

I did eventually get an answer over at experts-exchange; here's what worked:

function my_fputcsv($handle, $fieldsarray, $delimiter = "~", $enclosure ='"'){
   $glue = $enclosure . $delimiter . $enclosure;
   return fwrite($handle, $enclosure . implode($glue,$fieldsarray) . $enclosure.PHP_EOL);
}

用于代替标准fputcsv.

to be used in place of standard fputcsv.
