php文件重命名下载代码示例

 php文件重命名下载代码示例

Bata1.0、基础代码（file_exists仅支持本地，还有下载时文件名乱码问题）

<?php
$file = 'success.jpg';

if (file_exists($file)){
    header('Content-Description: File Transfer');
    header('Content-Type: application/octet-stream');
    header('Content-Disposition: attachment; filename='.basename($file));
    header('Content-Transfer-Encoding: binary');
    header('Expires: 0');
    header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
    header('Pragma: public');
    header('Content-Length: ' . filesize($file));
    ob_clean();
    flush();
    readfile($file);
    exit;
}
?>

 

Bata2.0、解决中文名显示乱码问题（但还是仅支持服务器本地）

 

//$down_url=$server_name.$renamefile_url.'/'.$renamefile_name;        //file_exists仅支持本地
$down_url=$renamefile_url.'/'.$renamefile_name;
//$sourcefile_name = iconv("UTF-8",'GBK',$sourcefile_name);
$sourcefile_name = urlencode($sourcefile_name);
$sourcefile_name = str_replace("+", "%20", $sourcefile_name);



if(file_exists($down_url)){

    $ua = $_SERVER["HTTP_USER_AGENT"];
    header('Content-Description: File Transfer');
    header('Content-Type: application/octet-stream');

    //header('Content-Disposition: attachment; filename='.basename($sourcefile_name));

    if (preg_match("/MSIE/", $ua)) {
    header('Content-Disposition: attachment; filename="' . $sourcefile_name . '"');
    } else if (preg_match("/Firefox/", $ua)) {
    header('Content-Disposition: attachment; filename*="utf8\'\'' . $sourcefile_name . '"');
    } else {
    header('Content-Disposition: attachment; filename="' . $sourcefile_name . '"');
    }

    header('Content-Transfer-Encoding: binary');
    header('Expires: 0');
    header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
    header('Pragma: public');
    header('Content-Length: ' . filesize($down_url));
    ob_clean();
    flush();
    readfile($down_url);
    exit;
}
else{
    echo '文件目录不存在';
}
