How to check for an SSL certificate?

Question

PHP

Tell me, please, how to check that the site uses SSL and pull out information about the certificate?
I can’t find the API, I don’t want to parse godaddy’s answer either

Answer 1

Look here - stackoverflow.com/questions/3081042/how-to-get-ssl...

Answer 2

It is not necessary to "pull" it - the certificate is transmitted with each connection, if it is https, of course.

Answer 3

openssl s_client -connect example.org:443
