PHP處理大檔案下載____PHP

思路：PHP一邊讀取檔案，一邊將讀取到的內容輸出到瀏覽器中

<?php/** * Created by PhpStorm. * User: Kung * Date: 15-10-21 * Time: 下午8:00 */set_time_limit(0);  //大檔案在讀取內容未結束時會被逾時處理，導致下載檔案不全。$fpath = 'the_file_path';$file_pathinfo = pathinfo($fpath);$file_name = $file_pathinfo['basename'];$file_extension = $file_pathinfo['extension'];$handle = fopen($fpath,"rb");if (FALSE === $handle)    exit("Failed to open the file");$filesize = filesize($fpath);header("Content-type:video/mpeg4");//更具不同的檔案類型設定header輸出類型header("Accept-Ranges:bytes");header("Accept-Length:".$filesize);header("Content-Disposition: attachment; filename=".$file_name);$contents = '';while (!feof($handle)) {    $contents = fread($handle, 8192);    echo $contents;    @ob_flush();  //把資料從PHP的緩衝中釋放出來    flush();      //把被釋放出來的資料發送到瀏覽器}fclose($handle);exit;
