$fp = fopen('php://output', 'a');// 输出Excel列名信息
$head = array("电子邮件");
foreach ($head as $i => $v) {// CSV的Excel支持GBK编码，一定要转换，否则乱码$head[$i] = iconv('utf-8', 'gbk', $v);
}// 将数据通过fputcsv写到文件句柄
fputcsv($fp, $head);// 计数器
$cnt = 0;
// 每隔$limit行，刷新一下输出buffer，不要太大，也不要太小
$limit = 100000;// 逐行取出数据，不浪费内存
$count = count($email);for($t=0;$t<$count;$t++) {$cnt ++;if ($limit == $cnt) { //刷新一下输出buffer，防止由于数据过多造成问题ob_flush();flush();$cnt = 0;}$row[] = $email[$t];foreach ($row as $i => $v) {$row[$i] = iconv('utf-8', 'gbk', $v);}fputcsv($fp, $row);unset($row);

这种方案对待简单的excel是可行的，但是需要制作复杂的excel就无能为力
