使用PHP CURL下载MP4文件

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, $data);
fclose($file);

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) "192.168.0.9" ["local_port"]=> 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.

var_dump(curl_getinfo($ch));
