My PHP 7.2, 7.3, 7.4 and 8.0 builds use OpenSSL 1.1.1, just like the official builds. I also have a special build of PHP 7.1 with OpenSSL Beware: the TS versions of PHP 7.0 and PHP 7.1 are "broken", in the words of the PHP 7.1 release manager.
PHP is a general-purpose scripting language geared towards web development. It was originally created by Danish-Canadian programmer Rasmus Lerdorf in 1994. The PHP reference implementation is now produced by The PHP Group.
