This function worked fine as long as I didn't use any ssh2_sftp* stuff. As soon as I did, the connection (from my webserver to my browser) was closed without any warning/error in any of the logfiles. So, this won't work



<?php

// ssh2_connect and ssh2_auth etc...

$sftp = ssh2_sftp($connection);

ssh2_disconnect(); // Causes the connection to be reset

?>



while this works



<?php

// ssh2_connect and ssh2_auth etc...

$sftp = ssh2_sftp($connection);

$connection = null; unset($connection);

?>

ssh2_disconnect(...) requires at least PHP 7 (as it requires PECL ssh2 >= 1.0, which the PECL documentation on https://pecl.php.net/package/ssh2 states: "ssh2 1.0 and above is PHP 7 only").



For PHP 5.x similar functionality, try setting the ssh2_connect session variable to null, or unsetting it completely - this should allow PHP's garbage collection close the connection.



Example:



$session=ssh2_connect(...); // open connection

// code here to use connection

$session = null; unset($session); // close connection
