ftp_ssl_connect
(PHP 4 >= 4.3.0, PHP 5)
ftp_ssl_connect — Opens an Secure SSL-FTP connection
说明
ftp_ssl_connect() opens a SSL-FTP connection to the specified host .
Note: Why this function may not exist ftp_ssl_connect() is only available if OpenSSL support is enabled into your version of PHP. If it's undefined and you've compiled FTP support then this is why. For Windows you must compile your own PHP binaries to support this function.
参数
- 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().
返回值
Returns a SSL-FTP stream on success or FALSE on error.
更新日志
| 版本 | 说明 |
|---|---|
| 5.2.2 | The function was changed to return FALSE when it can't use an SSL connection, instead of fallbacking to a non-SSL one as previously. |
