Description:
------------
I've tried to use this plugin on PHP7 (compiling from trunk / master).

It compiles and installs.  I can connect fine.

However it seems the file_exists function no longer reports true when using an ssh2_sftp resource handle.



Test script:
---------------
<?php
if (!function_exists("ssh2_connect")) die("function ssh2_connect doesn't exist");
// log in at server1.example.com on port 22
if(!($con = ssh2_connect("wherever", 22))){
    echo "fail: unable to establish connection\n";
} else {
    // try to authenticate with username root, password secretpassword
    if(!ssh2_auth_pubkey_file($con, "someuser", "/path/to/.ssh/id_rsa.pub", "/path/to/.ssh/id_rsa")) {
        echo "fail: unable to authenticate\n";
    } else {
        // allright, we're in!
        echo "okay: logged in...\n";

        // execute a command
        if (!($stream = ssh2_exec($con, "ls -al" ))) {
            echo "fail: unable to execute command\n";
        } else {
            echo "what came back from command:\n";
            // collect returning data from command
            stream_set_blocking($stream, true);
            $data = "";
            while ($buf = fread($stream,4096)) {
                $data .= $buf;
            }
            fclose($stream);
            echo $data;
            $sftp = ssh2_sftp($con);
            echo "\n";
            $result = file_exists("ssh2.sftp://$sftp/path/to/somefile");
            echo "\n";
            echo "\n";
            echo "\n";
            echo "file_exists: " . ($result ? "yes" : "no ");
            echo "\n";
        }
    }
}

Expected result:
----------------
....

file_exists: yes

Actual result:
--------------
....

file_exists: no

ssh2_* functions requires SSH2 extension.

For PHP 7, you need PECL SSH2 v1.0.0 or greather.

It was not exist at 2015-12-07 but now is available.

I've found this issue because of I've used PECL extension until today. For PHP 7.0.12 worked fine, but in 7.0.13 is broken. And I've has the same problem.

Solution: Compile latest versions where the bug with newest version is fixed: https://github.com/php/pecl-networking-ssh2/commit/17680cf039f0cfac53b5a2531fdb715b95e9cc42

This might well be fixed with this commit:

https://github.com/php/pecl-networking-ssh2/commit/17680cf039f0cfac53b5a2531fdb715b95e9cc42

Could you try current master and see if the problem is solved?
