  • php导出数据为CSV文件DEMO

    代码示例:

        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();
        }

    当然还有用fputcsv的,但我试了一下效果不太好。
