Given that openssl 1.1.0 only shipped late last year, I fail to see how this has been an failure in PHP for many years for not using a recent feature in openssl. Looking at the sources for ab.c, it appears to do things like PHP. The protocol level is hard coded to one value (SSL_METHOD *SSLv23_method(void);) There is a command line override (-Z protocol) that allows the protocol selection to be changed to TLS1, TLS1.1, TLS1.2, or TLS1+TLS1.1+TLS1.2. Lists, could you please clarify what PHP should learn from how ab does TLS?
