homebrew–brewinstallphp56intl装上了，但php并没有加载

系统 os x 10.11
用的是 brew 下的php56
brew 下的 nginx

下了一个项目，在安装过程中提示缺少，intl 和 apc扩展，就用下面的语句下载了，也装上了，但php还是没有加载，这怎么弄？
另外问下，apc 扩展怎么装，用 brew search php56 并没有 apc 扩展

不太清楚你具体的环境配置是怎么样的。不过需要注意的有如下：
php的ISAPI有好几个，cli模式，apache模式等等，可能每个模式都对应一个php.ini，是不是在正确的ini文件中添加extension=/path/path/intl.so了？
apc如果brew没有提供，那就只能手动编译安装了，一般步骤是这样的：
到apc源码根目录，phpize-》configure-》make-》make install，到ini文件中添加extension=/path/apc.so
