MongoDB PHP驱动程序不工作

我使用的是Mac OSX 10+，我的系统中使用的是Xampp。我需要安装PHP Mongodb驱动程序，将其连接到我的应用程序的Mongodb，但它不起作用，我尝试了以下步骤：

1. 使用安装的Mongodb驱动程序sudo /Applications/XAMPP/xamppfiles/bin/pecl install mongo
2. 添加extension="mongo.so" to php.ini /Applications/XAMPP/xamppfiles/etc

但在那之后，它不会让Apache Server启动；如果我从php.ini中删除extension="mongo.so"，那么它就可以重新启动

方法2:

1. 使用安装的Mongodb驱动程序sudo /Applications/XAMPP/xamppfiles/bin/pecl install mongodb
2. 将extension="mongodb.so"添加到php.ini /Applications/XAMPP/xamppfiles/etc

但在那之后，它不会让Apache Server启动；如果我从php.ini中删除extension="mongodb.so"，那么它就可以重新启动

我能够在/Applications/XAMPP/xamppfiles/lib/php/extensions/no-debug-non-zts-20131226 位置看到mongo.so和mongodb.so文件

我在Xampp的日志文件中得到的错误如下所示：
