I am trying to download a video from one of my servers to another of my servers. I was using CURL because copy() did not download the audio from the video. However, CURL downloaded corrupted files (?) and do not. This is how I'm downloading the MP4 file right now:

$source = "https://link.com/video.mp4";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $source);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_SSLVERSION,3);
$data = curl_exec ($ch);
$error = curl_error($ch);
curl_close ($ch);

$destination = "video/video.mp4";
$file = fopen($destination, "wb");
fwrite($file, $data);

Is there anything special for MP4 files to download properly?

array(26) { ["url"]=> string(60) "https://link.com/video.mp4" ["content_type"]=> NULL ["http_code"]=> int(0) ["header_size"]=> int(0) ["request_size"]=> int(0) ["filetime"]=> int(-1) ["ssl_verify_result"]=> int(1) ["redirect_count"]=> int(0) ["total_time"]=> float(0.135745) ["namelookup_time"]=> float(8.4E-5) ["connect_time"]=> float(0.056009) ["pretransfer_time"]=> float(0) ["size_upload"]=> float(0) ["size_download"]=> float(0) ["speed_download"]=> float(0) ["speed_upload"]=> float(0) ["download_content_length"]=> float(-1) ["upload_content_length"]=> float(-1) ["starttransfer_time"]=> float(0) ["redirect_time"]=> float(0) ["redirect_url"]=> string(0) "" ["primary_ip"]=> string(13) "AN-IP :D" ["certinfo"]=> array(0) { } ["primary_port"]=> int(443) ["local_ip"]=> string(11) "" ["local_port"]=> int(57478) }

我正在尝试将视频从我的一台服务器下载到另一台服务器。 我使用的是CURL,因为copy()没有从视频中下载音频。 但是,CURL下载了损坏的文件(?)而没有。 这就是我现在正在下载MP4文件的方式:

  $ source =“https://link.com/video.mp4";
$ch = curl_init  (); 
curl_setopt($ ch,CURLOPT_URL,$ source); 
curl_setopt($ ch,CURLOPT_RETURNTRANSFER,1); 
curl_setopt($ ch,CURLOPT_SSLVERSION,3); 
 $ data = curl_exec($ ch); 
  $ error = curl_error($ ch); 
curl_close($ ch); 
 $ destination =“video / video.mp4”; 
 $ file = fopen($ destination,“wb”); 
fwrite($  file,$ data); 
fclose($ file); 

MP4文件有没有什么特别的下载? < p> array(26){[“url”] =&gt; string(60)“https://link.com/video.mp4”[“content_type”] =&gt; NULL [“http_code”] =&gt; int(0)[“header_size”] =&gt; int(0)[“request_size”] =&gt; int(0)[“filetime”] =&gt; int(-1)[“ssl_verify_result”] =&gt; int(1)[“redirect_count”] =&gt; int(0)[“total_time”] =&gt; float(0.135745)[“namelookup_time”] =&gt; float(8.4E-5)[“connect_time”] =&gt; float(0.056009)[“pretransfer_time”] =&gt; float(0)[“size_upload”] =&gt; float(0)[“size_download”] =&gt; float(0)[“speed_download”] =&gt; float(0)[“speed_upload”] =&gt; float(0)[“download_content_length”] =&gt; float(-1)[“upload_content_length”] =&gt; float(-1)[“starttransfer_time”] =&gt; float(0)[“redirect_time”] =&gt; float(0)[“redirect_url”] =&gt; string(0)“”[“primary_ip”] =&gt; string(13)“AN-IP:D”[“certinfo”] =&gt; array(0){} [“primary_port”] =&gt; int(443)[“local_ip”] =&gt; string(11)“”[“local_port”] =&gt; int(57478)}

    You must open the file in binary mode to ensure file is saved to disk correctly.

    $file = fopen($destination, "wb");

    Also use fwrite instead of fputs

    fwrite($file, $data);

    Check that video.mp4 downloads from the browser correctly. Maybe it is redirecting? If so the add this option.

    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);

    If is still does not work then dump out this info and post it.
