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);
