homebrew - brew install php56-intl 裝上了，但php並沒有載入

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

下了一個項目，在安裝過程中提示缺少，intl 和 apc擴充，就用下面的語句下載了，也裝上了，但php還是沒有載入，這怎麼弄？
另外問下，apc 擴充怎麼裝，用 brew search php56 並沒有 apc 擴充

不太清楚你具體的環境配置是怎麼樣的。不過需要注意的有如下：
php的ISAPI有好幾個，cli模式，apache模式等等，可能每個模式都對應一個php.ini，是不是在正確的ini檔案中添加extension=/path/path/intl.so了？
apc如果brew沒有提供，那就只能手動編譯安裝了，一般步驟是這樣的：
到apc源碼根目錄，phpize-》configure-》make-》make install，到ini檔案中添加extension=/path/apc.so
