这个链接为mp3文件，当我点击它我无法下载它只是在浏览器中播放它如果我像IDM一样设置（互联网下载管理器）它会下载

Click here to show image from idm

我尝试在帖子中传递网址或获取但不起作用

<?php
    if(isset($_POST['comment']) && !empty($_POST['comment'])){

    $file = $_POST['comment'];
    header ("Content-type: octet/stream");
    header ("Content-disposition: attachment; filename=".$file.";");
    header("Content-Length: ".filesize($file));
    readfile($file);
    exit;
    }
?>

Answer 1

这与php无关，而是需要编辑.htaccess文件。这将强制mp3文件下载而不是播放

<FilesMatch "\.(?i:mp3)$">
  ForceType application/octet-stream
  Header set Content-Disposition attachment
</FilesMatch>

还有一个想法，将其添加到.htaccess我从here

获取

AddType application/octet-stream .mp3
AddType application/octet-stream .avi
AddType application/octet-stream .mpg
AddType application/octet-stream .mov
AddType application/octet-stream .pdf

Answer 2

尝试以下代码

if(isset($_POST['comment']) && !empty($_POST['comment'])){
    $fileName = 'test.mp3';
    $file = $_POST['comment'];
    ob_start();
    header('Content-type: audio/mpeg');
    header("Content-Transfer-Encoding: Binary");
    header('Content-Disposition: attachment; filename="'.basename($fileName).'"');
    file_put_contents($fileName, $file);
    readfile($fileName);
    ob_end_flush();
}

强制从url下载文件（声音，视频）和文件使用php
