让PHP更快的提供文件下载
原文链接： http://www.laruence.com/2012/05/02/2613.html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");
