openssl_free_key and openssl_pkey_free are probably aliases.
And the preferred one is probably openssl_pkey_free.
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.
PHP 8.0 Deprecated: Function openssl_free_key() is deprecated
