Here's a word of caution for all the Mac OS X Server SA's who are running Valentina/PHP. El Capitan's "rootless" SIP security protocol removes permissions and access to the "restricted" folders & files. Updating 10.11 also removes the PHP plugins from PHP.
You can also no longer edit or save those files in the PHP ini directory under /etc because of the SIP security feature. This took all my DBs off line after the update to El Capitan.
Solution: Boot to the Recovery Drive. In terminal, issue sudo csrutil disable. Reboot. This will disable the SIP feature and return your control of the file system.
You will have to download the PHP modules for OS X and place them back in to the Extension Dir per php.ini
