In php the function
is deprecated and not includde in php 8. Can somebody give an alternative for it?
This function is now deprecated as it doesn't have an effect anymore.
PHP 8 deprecates openssl_free_key (actually openssl_pkey_free which it aliases) and automatically destroys the key instance when it goes out of scope.
So really you replace it with nothing, as the resource is now cleaned up properly the same as anything else.
If you want to feel like you're going that extra mile you can call
unset() on it, but that's not a thing I would consider necessary.
