I'm looking for a way to connect to a FTPS server from PHP and I need to send a client certificate. I looked at the related questions, but they don't answer the question:
How to use a Client Certificate with ftp_ssl_connect Connecting to FTPS using PHP and certificate as auth
I now connect using ftp_ssl_connect but I don't see a way to send a certificate. Is the only possibility to rewrite the code and use something like curl? Or are there other options?
