让PHP更快的提供文件下载

我们可以使用Apache的module mod_xsendfile, 让Apache直接发送这个文件给用户:
<?php $file = "/tmp/中文名.tar.gz"; $filename = basename($file); header("Content-type: application/octet-stream"); //处理中文文件名 $ua = $_SERVER["HTTP_USER_AGENT"]; $encoded_filename = rawurlencode($filename); if (preg_match("/MSIE/", $ua)) { header('Content-Disposition: attachment; filename="' . $encoded_filename . '"'); } else if (preg_match("/Firefox/", $ua)) { header("Content-Disposition: attachment; filename*=\"utf8''" . $filename . '"'); } else { header('Content-Disposition: attachment; filename="' . $filename . '"'); } //让Xsendfile发送文件 header("X-Sendfile: $file");
