php导出数据为CSV文件DEMO

private function _download_send_headers($filename) {
// disable caching
$now = gmdate("D, d M Y H:i:s");
header("Expires: Tue, 03 Jul 2001 06:00:00 GMT");
header("Cache-Control: max-age=0, no-cache, must-revalidate, proxy-revalidate");
header("Last-Modified: {$now} GMT");

// force download
header("Content-Type: application/force-download");
header("Content-Type: application/octet-stream");
header("Content-Type: application/download");

// disposition / encoding on response body
header("Content-Disposition: attachment;filename={$filename}");
header("Content-Transfer-Encoding: binary");
}

private function _array2csv($array) {
if (count($array) == 0) {
return null;
}
$keys = array_keys(reset($array));
echo implode(',', $keys) . PHP_EOL;
for ($i = 0, $j = count($array); $i < $j; $i++) {
echo implode(',', $array[$i]) . PHP_EOL;
}
}

public function saveAsCsv() {
$this -> _download_send_headers("data_export_" . date("Y-m-d") . ".csv");
$ret = array(
array(
'id' => 1,
'name' => 'hello'
),
array(
'id' => 2,
'name' => 'world'
),
array(
'id' => 3,
'name' => 'good'
),
);
$this -> _array2csv($ret);
die();
}

fputcsv的，但我试了一下效果不太好。
