Description:
------------
'php_ssh2-1.0-7.1-nts-vc14-x64' is erratic compared with 'php_ssh2-1.0-7.0-nts-vc14-x64'.

At least this is working wrong in case of the PHP 7.1 release:

is_dir('ssh2.sftp://' . ssh2_sftp(ssh2_connect($host, $port)) . '$absolute_path_to_remote_directory')

Resolution:

In case of a valid folder with appropriate permissions:

php_ssh2-1.0-7.0-nts-vc14-x64 returns 'true' while
php_ssh2-1.0-7.1-nts-vc14-x64 returns' false'

This has been found while using PHPLOY (https://github.com/banago/PHPloy) on my Windows 10 x64 Pro system using PHP 7.0 (NTS) x64 and PHP 7.1 (NTS) x64 - both VS14 compliations.

Test script:
---------------
is_dir('ssh2.sftp://' . ssh2_sftp(ssh2_connect($host, $port)) . '$absolute_path_to_remote_directory');

Exakt same Issue with PHP 7.1.2 (SSH-2.0-libssh2_1.4.2)

Worked fine with php 5.6.23 (SSH-2.0-libssh2_1.4.2)

System is a Debian 7

my workaround is:

$streamCheck = ssh2_exec($this->getSshConnection(), 'test -d '.escapeshellarg($folder).' && echo 1 || echo 0');
stream_set_blocking($streamCheck, true);
$streamCheck_out = ssh2_fetch_stream($streamCheck, SSH2_STREAM_STDIO);

before it was: is_dir('ssh2.sftp://'.$this->getSftpConnection().$folder) -> this returns now always false

You must use intval on the result from ssh2_sftp now, per http://php.net/manual/en/function.ssh2-sftp.php

So instead, use this:
$ssh2 = ssh2_connect($host, $port);
$sftp = ssh2_sftp($ssh2);
is_dir('ssh2.sftp://' . intval($sftp) . $absolute_path_to_remote_directory)

This is supposed to be fixed as of ssh2 1.1.
