Example #1 锟斤拷一锟斤拷锟筋动锟斤拷锟斤拷锟叫达拷锟街斤拷锟斤拷

<?php
$session = ssh2_connect('example.com', 22);
ssh2_auth_pubkey_file($session, 'username', '/home/username/.ssh/id_rsa.pub',
                                            '/home/username/.ssh/id_rsa', 'secret');
$stream = fopen("ssh2.tunnel://$session/remote.example.com:1234", 'r');
?>

Example #2 This $session variable must be kept available!

In order to use the ssh2.*://$session wrappers you must keep the $session resouce variable. The code below will not have the desired effect:

<?php
$session = ssh2_connect('example.com', 22);
ssh2_auth_pubkey_file($session, 'username', '/home/username/.ssh/id_rsa.pub',
                                            '/home/username/.ssh/id_rsa', 'secret');
$connection_string = "ssh2.sftp://$session/";
unset($session);
$stream = fopen($connection_string . "path/to/file", 'r');
?>

unset() closes the session, because $connection_string does not hold a reference to the $session variable, just a string cast derived from it. This also happens when the unset() is implicit because of leaving scope (like in a function).
