 Using [PHPBrew](https://github.com/phpbrew/phpbrew) to build/manage multiple versions of PHP is helpful.

+## Knowning OpenSSL related issue (Unix only)
+
+* With php5.5 and openssl-3.0.2, signing functions will not work
+* When your php loads a different version of openssl than your system openssl version, awscrt may fail to load.
+
+The easiest workaround to those issue is to build from source and get aws-lc as libscrypto for awscrt to depend on instead of your local openssl. Same instructions as [here](#building-from-github-source), but use `USE_OPENSSL=OFF make` instead of `make`
