How to enable ZTS?

[kyletaylored]

I'm trying to use the Parallel extension, which isn't part of homebrew-extensions, but the minimum requirement is to have ZTS enabled.

checking for ZTS... configure: error: parallel requires ZTS, please use PHP with ZTS enabled

Is there a way to enable thread safety when installing via homebrew, or do I need to manually compile it?

This tap does not have zts builds yet. You will have to compile it yourself. you can edit the formula file and build from source.
