导出数据按一定要求的格式写入CSV文件

例如：需要输出来的格式为下
"goods_id","price","shipfee"这是字段
导出来的数据
"1","10","15"
"2","12","5"
"3","13","4"

$filename = "2.csv";

$handle = fopen($filename, "w");

$field = array("goods_id", "price", "shipfee");
$data = array(
    array("1","10","15"),
    array("2","12","5"),
    array("3","13","4")
);

//写入字段
fputcsv($handle, $field);
//写入数据
foreach($data as $k=>$v)
{
    fputcsv($handle, $v);
}
fclose($handle);
?>
