When trying to install APCu via brew I get the error
PHP Warning: PHP Startup: Unable to load dynamic library '/usr/local/opt/php56-apcu/apcu.so' - dlopen(/usr/local/opt/php56-apcu/apcu.so, 9): Symbol not found: _zend_signal_globals Referenced from: /usr/local/opt/php56-apcu/apcu.so Expected in: flat namespace in /usr/local/opt/php56-apcu/apcu.so in Unknown on line 0
This occurs no matter how I install APCu
brew install php56-apcu
brew install --build-from-source php56-apcu
brew install php56-apcu --enable-apc-bc
APC fails to appear in phpinfo
too.
Opcache is install fine, as is php-intl
