PHP 想要往 MongoDB 里增删查改数据，需要先安装 mongodb 扩展模块：

cd /usr/local/src/wget https://pecl.php.net/get/mongodb-1.3.0.tgz tar zxvf mongodb-1.3.0.tgzcd mongodb-1.3.0/usr/local/php/bin/phpize./configure --with-php-config=/usr/local/php/bin/php-configmake && make installecho ‘extension = "mongodb.so"‘ >> /usr/local/php/etc/php.ini/usr/local/php/bin/php -m | grep mongo/etc/init.d/php-fpm restart
