I just checked the code for PHP 7.1 and in there openssl_free_key is an alias for opnessl_pkey_free (PHP_FALIAS).
This supports Richards assumption.
I would also suggest to not use the alias,
but use the openssl_pkey_free function in new code.
This is because it is more descriptive about what its intend is and is the same structure as similar function in the openssl section.
openssl_free_key
(PHP 4 >= 4.0.4, PHP 5, PHP 7, PHP 8)
openssl_free_key — Free key resource
Avviso
This function has been DEPRECATED as of PHP 8.0.0. Relying on this function is highly discouraged.

openssl_free_key and openssl_pkey_free are probably aliases.
And the preferred one is probably openssl_pkey_free.
