ftp_ssl_connect
(PHP 4 >= 4.3.0, PHP 5, PHP 7)
ftp_ssl_connect — Opens a Secure SSL-FTP connection
Opis
$host
[, int $port = 21
[, int $timeout = 90
]] ) : resource
ftp_ssl_connect() opens an explicit SSL-FTP connection to the
specified host. 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.
Informacja: Why this function may not exist
Before 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.
Informacja:
ftp_ssl_connect() is not intended for use with sFTP. To use sFTP with PHP, please see ssh2_sftp().
Parametry
-
host -
The FTP server address. This parameter shouldn't have any trailing slashes and shouldn't be prefixed with ftp://.
-
port -
This parameter specifies an alternate port to connect to. If it is omitted or set to zero, then the default FTP port, 21, will be used.
-
timeout -
This parameter specifies the timeout for all subsequent network operations. If omitted, the default value is 90 seconds. The timeout can be changed and queried at any time with ftp_set_option() and ftp_get_option().
Zwracane wartości
Returns a SSL-FTP stream on success or FALSE on error.

The function was changed to return FALSE when it can't use an SSL
connection, instead of falling back to a non-SSL one as previously.
