用php下載數字下載鏈接

Question

我用這個功能下載數字下載鏈接。 test.zip發送我的瀏覽器，但文件大小未知，當我下載它並打開顯示此錯誤：「存檔是未知格式或損壞」 test.zip文件夾內和download.php內部根目錄。

downloadFile('file/','test.zip',900,false); 

?> 

Answer 1

我讀了這個功能的代碼，我解決了這個問題：

1-

$fileLocation = $fileLocation . $fileName; 

$ fileLocation用來讀取文件，但它僅包含文件夾的名字！

2-

$range = str_replace($range, "-", $range); 

str_replace函數替換爲 「 - 」 字符，但不更新$範圍VAR

3-

set_magic_quotes_runtime 

已過時，我調用函數前加檢查！

你可以從我github下載新的代碼;）

Answer 2

擺脫文件末尾的?>。

如果這不起作用，可以在zip文件的某個地方看到它。
