Streaming local file from PHP while it’s been written to by a CURL process

Posted on 16th Feb 2014 by admin

I am creating a simple Proxy server for my website. Why I am not using mod_proxy and mod_cache is a different discussion. Here's the code:

shell_exec("nohup curl --create-dirs -o {$write_path} {$source_url} > /dev/null 2> /dev/null & echo $!");
sleep(1);

$read_speed = 65.5; # 65.5 kb/s download rate
$handle = fopen($write_path, "rb");

$content_type = select_meta_item($headers, 'Content-Type');
$file_size = select_meta_item($headers, 'Content-Length');
send_headers($content_type, $file_size);
flush();

while (!feof($handle))
{
echo fread($handle, round($read_speed * 1024));
flush();
sleep(1);
}

fclose($handle);
Streaming an MP3 doesn't work using this method. Plays in Chrome, but not in Firefox. Initially I'll be using this to stream MP3 files through Long Tail's JW Player. If it all works out, I'll also be using this to send ZIP files
