所有Mp3文件僅以3kb下載並損壞

此代碼強制在Chrome和Mozilla上爲我下載。但問題是所有文件大小都是3kb。爲什麼？大小是不同的像3MB，4MB，3.5MB和下載文件只是一個腐敗的3kb ...請幫助。所有Mp3文件僅以3kb下載並損壞

注意：如果使用標題重定向，它可以在Chrome中正常下載或在其他瀏覽器中打開並在不下載的情況下開始播放。

使用完整的本地路徑'/路徑//mp3'的，而不是''中的文件路徑$ = SITE_URL SITE_URL'。「音樂/".$ file' –

這並沒有解決問題。我已經嘗試過101％的確定。 'SITE_URL。「music /」.$ file'和'/ path/to/my/mp3'仍然是相同的輸出 –

在代碼編輯器中打開mp3文件。錯誤信息應該在你的3kb mp3文件中。 – vishva8kumara

當您執行讀取文件時，您已經寫入了包含文件和一些HTML到輸出緩衝區。這將導致媒體文件損壞。您可能希望在發送任何HTML內容之前先放入readfile並退出（或die（））。

而SITE_URL不適用於$ filePath。您可能需要通過預先

...dirname(dirname(__file__))...

謝謝** Vishva8kumara **。我已經刪除了所有輸出，並且它的大小爲零字節。以下是新代碼 –

現在將塊頭註釋爲頭部分，以便您更願意在瀏覽器中看到mp3文件內容。這將更容易調試代碼，因此您可以取消註釋頭。 – vishva8kumara

然後，代替readfile，回顯$ filePath並查看是否獲得了正確的文件路徑。 – vishva8kumara

感謝Vishva8kumara找到正確的文件路徑。我已經刪除了所有的輸出，並且它的大小爲零字節，並且文件已損壞。下面是新的代碼

      $checkFile = "SELECT * FROM files WHERE f_song = '$file' AND f_del='0'"; 
      $checkFileRun = mysqli_query($con, $checkFile); 
      $fileName = mysqli_fetch_assoc($checkFileRun); 
      //$song = $fileName['f_song'];

       $filePath = "http://localhost/du/music/".$file; 
       $fileSize = filesize($filePath);
