目前我正在使用下面的php代碼來下載文件。Php文件下載問題?
PHP代碼:
<?php
timeout();
//require_once("config.php");
if(!isset($_SESSION['front_username']) && isset($_SESSION['front_username']) == "" &&
!isset($_SESSION['front_password']) && isset($_SESSION['front_password']) == "" &&
!isset($_SESSION['user_id']) && isset($_SESSION['user_id']) == "") {
header("Location:login.php");
exit();
}
$file_get = $_GET['filename'];
$tmp = explode(".",$file_get);
$file_name1 = substr($file_get, 33);
switch ($tmp[count($tmp)-1]) {
case "pdf": $ctype="application/pdf"; break;
case "exe": $ctype="application/octet-stream"; break;
case "zip": $ctype="application/zip"; break;
case "docx":
case "doc": $ctype="application/msword"; break;
case "csv":
case "xls":
case "xlsx": $ctype="application/vnd.ms-excel"; break;
case "ppt": $ctype="application/vnd.ms-powerpoint"; break;
case "gif": $ctype="image/gif"; break;
case "png": $ctype="image/png"; break;
case "jpeg":
case "jpg": $ctype="image/jpg"; break;
case "tif":
case "tiff": $ctype="image/tiff"; break;
case "psd": $ctype="image/psd"; break;
case "bmp": $ctype="image/bmp"; break;
case "ico": $ctype="image/vnd.microsoft.icon"; break;
default: $ctype="application/force-download";
}
header("Pragma: public"); // required
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Cache-Control: private",false); // required for certain browsers
header("Content-Type: $ctype");
header("Content-Disposition: attachment; filename=\"".$file_name1."\";");
header("Content-Transfer-Encoding: binary");
header("Content-Length: ".filesize("upload_doc/$file_get"));
ob_clean();
flush();
readfile("upload_doc/$file_get");
?>
它的下載正確,如果上傳的文件名是字母。但是,如果上傳的文件名具有該文本,例如my doC#2.doc
或dev & developer.doc
,則它正在下載但未顯示。在我下載的文件夾中,我看到my doc
。
我不明白我的代碼有什麼問題,有人可以告訴我嗎?
我看到的第一個問題是在這一行** $ file_name1 = subs tr($ file_get,33); **您將從文件名中截斷前32個字符。爲什麼這樣? – Diptendu 2014-12-07 10:57:41
@Diptendu例如:原始上傳的文件名重命名爲:'35dbde7e8eab023248adf616747caf6e-bind candidate#2.doc',當我下載它時,我只想顯示用戶上傳的名稱。 – creativeartbd 2014-12-07 11:02:25
好的。所以你想刪除MD5部分。得到它了。謝謝!! – Diptendu 2014-12-07 11:04:07
