how to use server certificate to encrypt data, then use private cert/signature to decrypt?

[Notgiven]

A book (Pro PHP Security) I read has some details about it but it is not
very clear and I need to learn more.

What I gleaned is possible in this book is that the php code can encrypt
data using the server's public key certificate before sending it to the
database. Then the user, who has a private key created from that servers's
public key, is the only one who can decrypt the data.

This is similar to the way Lotus Notes works with PKI and X.509 certs.

Any links or how-tos where I can learn more is MUCH appreciated!

This is exactly the same as how Lotus Notes works with PKI and x509 certs.

OMG, is Google down?

Try the SSL certificates Howto, and the SSL functions in the PHP manual.
