How to use a Client Certificate with ftp_ssl_connect

I'm looking for the best method to work with an FTP server over an SSL connection. (Generally, pushing a file up as well as getting a list of files on the server). One requirement for this project is that I must use a client side X.509 certificate as part of the authentication process.

Can I use a cl开发者_开发百科ient certificate using the php function ftp_ssl_connect. If so, how? The only other option I've been able to identify would be using curl to work via FTPS.

Any suggestions or thoughts would be greatly appreciated!

You could use PHP's stream context functions which allow setting SSL client certificates. Use the created context with standard functions like fopen.
