ftp_ssl_connect
ftp_ssl_connect opens an explicit SSL-FTP connection to the specified hostname. That implies that ftp_ssl_connect will succeed even if the server is not configured for SSL-FTP, or its certificate is invalid. Only when ftp_login is called, the client will send the appropriate AUTH FTP command, so ftp_login will fail in the mentioned cases.
Note:
Why this function may not existBefore PHP 7.0.0, ftp_ssl_connect was only available if both the ftp module and the OpenSSL support have been built statically into php; this means that on Windows this function had been undefined in the official PHP builds. To have this function available on Windows, it had been necessary to compile own PHP binaries.
Note:
ftp_ssl_connect is not intended for use with sFTP. To use sFTP with PHP, please see ssh2_sftp.
