ssh2.tunnel://user:pass@example.com:22/192.168.0.1:14
ssh2.sftp://user:pass@example.com:22/path/to/filename
This wrapper is not enabled by default:
In order to use the ssh2.*:// wrappers you must install
the SSH2 extension
available from PECL .
In addition to accepting traditional URI login details, the ssh2 wrappers
will also reuse open connections by passing the connection resource in the
host portion of the URL.
Example M-3. Opening a stream from an active connection
<?php = ssh2_connect ( 'example.com' , 22 ); ssh2_auth_pubkey_file ( $session , 'username' , '/home/username/.ssh/id_rsa.pub' , '/home/username/.ssh/id_rsa' , 'secret' ); $stream = fopen ( "ssh2.tunnel://$session/remote.example.com:1234" , 'r' ); ?>
