# ssh2_fetch_stream

(PECL)

ssh2_fetch_stream -- Fetch an extended data stream

## Description

resource ssh2_fetch_stream ( resource channel, int streamid )

Fetches an alternate substream associated with an SSH2 channel stream identified by streamid. The SSH2 protocol currently defines only one substream, STDERR, which has a substream ID of `SSH2_STREAM_STDERR` (defined as 1).

Example 1. Opening a shell and retrieving the stderr stream associated with it.
`<?php $connection = ssh2_connect('shell.example.com', 22); ssh2_auth_password($connection, 'username', 'password'); $stdio_stream = ssh2_shell($connection); $stderr_stream = ssh2_fetch_stream($stdio_stream, SSH2_STREAM_STDERR); ?>`
