Idea: While PHP reads the file, it outputs the read content to the browser
<?php /** * Created by PhpStorm. * User: Kung * Date: 15-10-21 * Time: 下午8:00 */ set_time_limit(0); //大文件在读取内容未结束时会被超时处理,导致下载文件不全。 $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");//更具不同的文件类型设置header输出类型 header("Accept-Ranges:bytes"); header("Accept-Length:".$filesize); header("Content-Disposition: attachment; filename=".$file_name); $contents = ''; while (!feof($handle)) { $contents = fread($handle, 8192); echo $contents; @ob_flush(); //把数据从PHP的缓冲中释放出来 flush(); //把被释放出来的数据发送到浏览器 } fclose($handle); exit;
The above introduces PHP's processing of large file downloads, including the content of reading files. I hope it will be helpful to friends who are interested in PHP tutorials.
