Non blocking up/downloads using ssh2_sftp

Question

How can I use non-blocking up/downloads with ssh2_sftp_ (like with ftp_nb_put/ftp_nb_get)?

Answer 1

The PHP SSH2 functions do not support non-blocking operation. Neither phpseclib does.

But you can move your download code to a separate thread using the Thread PECL class.

For an example see:

Or you can upload the file in chunks.
