我想製作一個PHP腳本來下載一個AVI文件。該文件在我的服務器上,我想將其發送給用戶。我做了下面的腳本,但是當我運行它時,我只會得到一個0 KB的大AVI文件。PHP頭附加AVI文件
誰能告訴我我做錯了什麼?
$file_path = "downloads/test.avi";
// Get filename
$filename = explode("/", $file_path);
$filename = $filename[count($filename)-1];
if(file_exists($file_path)) {
$file_extension = strtolower(substr(strrchr($file_path, "."), 1));
// This will set the Content-Type to the appropriate setting for the file
switch($file_extension) {
case "pdf":
$ctype = "application/pdf";
break;
case "exe":
$ctype = "application/octet-stream";
break;
case "zip":
$ctype = "application/zip";
break;
case "doc":
$ctype = "application/msword";
break;
case "xls":
$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":
$ctype = "image/jpg";
break;
case "jpg":
$ctype = "image/jpg";
break;
case "mp3":
$ctype = "audio/mpeg";
break;
case "wav":
$ctype = "audio/x-wav";
break;
case "mpeg":
$ctype = "video/mpeg";
break;
case "mpg":
$ctype = "video/mpeg";
break;
case "mpe":
$ctype = "video/mpeg";
break;
case "mov":
$ctype = "video/quicktime";
break;
case "avi":
$ctype = "video/x-msvideo";
break;
case "src":
$ctype = "plain/text";
break;
default:
$ctype = "application/force-download";
}
$filesize = filesize($file_path);
// Set content type
header("Content-type: " . $ctype);
// Download file
header("Content-Disposition: attachment; filename=\"" . $filename . "\"");
// Set size of file
header("Content-Length: " . $filesize);
readfile($file_path);
這是我在Firefox從的LiveHTTPHeaders得到(出於某種原因Content-Length
爲零):

請注意:使用帶鍵的數組作爲文件擴展名和值作爲它們的MIME類型。將減少你的代碼,並且可能更容易編輯 – hakre
readfile()返回讀取的字節數,你能檢查它是否真的讀取文件嗎?可能是權限問題。 – sanmai
