php中强制下载文件的代码(解决了IE下中文文件名乱码问题)
浏览器提交excel格式的数据和文件名到服务器上,将请求转化为可下载的excel文件,并要求浏览器弹出文件下载提示窗口
中间遇到一个问题是提交的中文文件名直接放到header里在IE下会变成乱码,解决方法是将文件名先urlencode一下再放入header,如下。
-
<?php
-
$file_name = urlencode($_REQUEST['filename']);
-
header("Pragma: public"); header("Expires: 0");
-
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
-
header("Content-Type: application/force-download");
-
header('Content-Type: application/vnd.ms-excel; charset=utf-8');
-
header("Content-Transfer-Encoding: binary");
-
header('Content-Disposition: attachment; filename='.$file_name);
-
echo stripslashes($_REQUEST['content']);
-
?>
解决PHP Header下载文件在IE文件名中文乱码有两种常见的,一种是是把页面编码改成utf8,另一种是对中文url进入urlencode编码就可以解决了。
解决方案一(我的页面是utf-8编码):
-
$filename = "中文.txt";
-
$ua = $_SERVER["HTTP_USER_AGENT"];
-
$encoded_filename = urlencode($filename);
-
$encoded_filename = str_replace("+", "%20", $encoded_filename);
-
header('Content-Type: application/octet-stream');
-
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 . '"');
-
}
解决方法二
将文件名先urlencode一下再放入header,如下。
-
<?php
-
$file_name = urlencode($_REQUEST['filename']);
-
header("Pragma: public"); header("Expires: 0");
-
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
-
header("Content-Type: application/force-download");
-
header('Content-Type: application/vnd.ms-excel; charset=utf-8');
-
header("Content-Transfer-Encoding: binary");
-
header('Content-Disposition: attachment; filename='.$file_name);
-
echo stripslashes($_REQUEST['content']);
-
?>
