这篇文章主要为大家详细介绍了php中强制下载文件(解决了IE下中文文件名乱码问题)的简单示例,具有一定的参考价值,可以用来参考一下。
感兴趣的小伙伴,下面一起跟随四海网的小编小韵来看看吧!
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。代码如下:
<?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']);
?>
代码如下:
$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 . '"');
}
代码如下:
<?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']);
?>
