卷曲以获得依恋并改变其内容

Question

我试图用curl获取m3u文件。该文件作为服务器响应的附件，如下所示：Content-Disposition: attachment; filename="myfile.m3u"。

在我的php页面中使用curl，我需要获取该m3u文件，更改其内容并将更改的内容作为新的m3u文件返回。

<?php
ini_set('display_errors', 1);
//add these to make your php file a downloadable m3u. 
//Without this VLC won't know how to process it.
//header('Content-Type: audio/x-mpegurl');
//header("Content-Transfer-Encoding: Binary"); 


function file_get_contents_curl($url) {
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    //curl_setopt($ch, CURLOPT_HEADER, 1);
    //curl_setopt($ch, CURLOPT_AUTOREFERER, TRUE);
    //curl_setopt($ch, CURLINFO_CONTENT_TYPE, "application/octet-stream");


    //curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
    curl_setopt($ch, CURLOPT_BINARYTRANSFER, TRUE);

    //curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);  



    $info = curl_getinfo($ch);
    $data = curl_exec($ch);
    curl_close($ch);


    return $data;
}


$url = 'myurltogetfile';

$fileContent = file_get_contents_curl($url);

echo $fileContent;
?>

有什么想法吗？

谢谢你！
