ftp_ssl_connect

ftp_ssl_connect

(PHP 4 >= 4.3.0, PHP 5)

ftp_ssl_connectOpens an Secure SSL-FTP connection

说明

resource ftp_ssl_connect ( string $host [, int $port = 21 [, int $timeout = 90 ]] )

ftp_ssl_connect() opens an explicit SSL-FTP connection to the specified host.

Note: Why this function may not exist

ftp_ssl_connect() is only available if both the ftp module and the OpenSSL support is built statically into php, this means that on Windows this function will be undefined in the official PHP builds. To make this function available on Windows you must compile your own PHP binaries.

Note:

ftp_ssl_connect() is not intended for use with sFTP. To use sFTP with PHP, please see ssh2_sftp().

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.

范例
