    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

    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);
    ?>

    If you derive an sftp connection from an ssh connection you must close the sftp connection before closing the ssh connection if you use ssh2_dissconnect. In other words:

    <?php
    $ssh_con    =ssh2_connect($sftp_server);
    ssh2_auth_password($ssh_con, $sftp_user, $sftp_pass);
    $scp_con=ssh2_sftp($ssh_con);

    # do stuff with $scp_con

    ssh2_disconnect($scp_con);
    ssh2_disconnect($ssh_con);
    ?>
