PHP 5.6.40 Windows, FTPS connection failed (SSL/TLS handshake failed) - php

Question

I'm trying to connect to a FTPS Server with PHP 5.6.40 on Windows.
I know that I need to recompile PHP to include OpenSSL and FTP in the PHP bundle and that's what I did.
The ftp_ssl_connect function is here now but I get a SSL/TLS handshake error.
When I try to connect to a public FTPS Server, I encounter the following error:
Warning: ftp_login(): SSL/TLS handshake failed in D:\home\site\wwwroot\index.php on line 13
PHP Warning: ftp_login(): SSL/TLS handshake failed in D:\home\site\wwwroot\index.php on line 13 PHP Warning: ftp_login(): AUTH command ok. Expecting TLS Negotiation. in D:\home\site\wwwroot\index.php on line 13
Warning: ftp_login(): AUTH command ok. Expecting TLS Negotiation. in D:\home\site\wwwroot\index.php on line 13
This script runs great on PHP 5.6.40/Linux.
I tried too, to have the same result with cURL commands, It's great on Windows and Linux, but I would really like to use PHP's FTP commands.
Any idea ?
<?php
$ftpserver = "test.rebex.net";
$user = "demo";
$mdp = "password";
$connectionId = ftp_ssl_connect($ftpserver);
$login_result = ftp_login($connectionId, $user, $mdp);
ftp_pasv($connectionId, true);
$pasv_result = ftp_pasv($connectionId, true);
if ($pasv_result)
echo "ok";
else
echo "nok";
print_r( ftp_nlist($connectionId,'.'));
