Question

I take the some youtube videos to my server with copy(); function but youtube give approximately 100kb/s speed with one connection ( my server has 100 mbit/s connection )

Is it possible to take more then 1 connection and reach faster speed with copy() function or sth else ?

Answer 1

Well, if you want to download / copy multiple URL from an external source concurrently,
curl_multi_exec is what you are look for.

This is a library made to synchronous curl multiple URL,
with the expenses of network bandwidth (and perhaps a little of CPU)

If you are looking to split a download,
once again, curl has the split option

RANGES

  With HTTP 1.1 byte-ranges were introduced. Using this, a client can request
  to get only one or more subparts of a specified document. Curl supports
  this with the -r flag.

  Get the first 100 bytes of a document:

        curl -r 0-99 http://www.get.this/

  Get the last 500 bytes of a document:

        curl -r -500 http://www.get.this/

  Curl also supports simple ranges for FTP files as well. Then you can only
  specify start and stop position.

  Get the first 100 bytes of a document using FTP:

        curl -r 0-99 ftp://www.get.this/README
