[MongoDB] mongodb与php - 陶士涵

windows上安装mongodb的php扩展

下载地址https://s3.amazonaws.com/drivers.mongodb.org/php/index.html

找到对应的php版本的dll文件，下载php_mongo.dll，放到php安装目录下的ext目录中，修改php.ini，添加一项extension=php_mongo.dll，没有找到支持php7的dll

 

 

 

获取MongoClient对象，new出来

获取数据库对象db，通过MongoClient对象的数据库属性，$MongoClient->数据库名

获取集合collection，通过db对象的集合属性，$db->集合名

创建集合，调用db对象的createCollection()方法，

调用collection对象的find()方法，查询数据，$collection->find()

调用collection对象的update ()方法，更新数据，$collection->update($condition,$data);

调用collection对象的insert ()方法，插入数据，$collection->insert($data);
