For fix this issue, you need to try to update brew to latest version:

brew update 
brew upgrade

If you already update to the latest version, but you still facing this issue. There are two another way:

1. Change OpenSSL Version

brew switch openssl 1.0.2s

2. Remove and Install clean PHP

brew rm php
brew fetch -f php
brew install php

Conclusion

Somehow, there can be a bug Library not loaded when you try to do installation in homebrew. So, for fix it, make sure you do some clean installation with your package again.
