negative.code: 
  PHP extensions are easily enabled by setting the `PHP_EXTENSIONS` or `ZEND_EXTENSIONS` option in `.bp-config/options.json`. Use these options to install bundled PHP extensions.
  
  If an extension is already present and enabled in the compiled php, for example `intl`, you do not need to explicitly enable it through `PHP_EXTENSIONS` or `ZEND_EXTENSIONS` in `.bp-config/options.json` to use that extension.
