My PHP 7.2, 7.3 and 7.4 builds use OpenSSL 1.1.1, just like the official builds. I also have a special build of PHP 7.1 with OpenSSL 1.1.1.
All other builds use OpenSSL 1.0.2 (fips), while php.net used OpenSSL 0.9.8 for 5.3 & 5.4, OpenSSL 1.0.1 for 5.5 & 5.6 and OpenSSL 1.0.2 for PHP 7.0 & 7.1. Be careful with mixing my extensions with the official binaries.
