【问题描述】：
我刚刚通过 Brew 在 Mac OSX 10.10.1 上执行了全新的 php 5.5(.19) 安装，并将 Brew 安装中的 libphp5.so 符号链接到 /usr/libexec/apache2/libphp5.so。
通过 Apache 使用 phpinfo() 启动脚本告诉我加载的 php.ini 文件位于 /usr/local/etc/php/5.5/php.ini。
我已将此添加到php.ini 的底部：
extension=memcache.so
extension=memcached.so
extension=imagick.so
extension=mongo.so
extension=mcrypt.so
我应该提到这些模块也随 Brew 一起安装。当使用 PHP 作为 Apache 模块时，它们可以毫无问题地加载。但是，当从终端使用 php 时，我收到以下输出：
PHP Warning: PHP Startup: Unable to load dynamic library '/usr/local/Cellar/php55/5.5.19/lib/php/extensions/no-debug-non-zts-20121212/memcache.so' - dlopen(/usr/local/Cellar/php55/5.5.19/lib/php/extensions/no-debug-non-zts-20121212/memcache.so, 9): image not found in Unknown on line 0

运行时：
php --ini
我收到输出：
Configuration File (php.ini) Path: /usr/local/etc/php/5.5
Loaded Configuration File: /usr/local/etc/php/5.5/php.ini
Scan for additional .ini files in: /usr/local/etc/php/5.5/conf.d
Additional .ini files parsed: /usr/local/etc/php/5.5/conf.d/ext-memcache.ini,
/usr/local/etc/php/5.5/conf.d/ext-memcached.ini,
/usr/local/etc/php/5.5/conf.d/ext-xdebug.ini
所以我可以看到，加载的配置文件与作为 Apache 模块运行时使用的配置文件相同。
跑步：
php -v
给我：
PHP 5.5.19 (cli) (built: Nov 25 2014 11:47:10)
Copyright (c) 1997-2014 The PHP Group
Zend Engine v2.5.0, Copyright (c) 1998-2014 Zend Technologies
with Xdebug v2.2.6, Copyright (c) 2002-2014, by Derick Rethans
所以我知道它使用了正确的安装（Yosemite 默认的 PHP 版本是 5.5.14）。
我似乎无法找出为什么在使用 Apache 时扩展加载没有问题，但在使用 CLI 时却没有。如何消除此警告？
