mongodb+php实现简单的增删改查

?php
// 连接到mongodb
$mongoClient = new MongoClient();
// 选择一个数据库
$db = $mongoClient->test;

//获取集合
$collection=$db->users;

//更新文档
$condition=array();
$condition["id"]=1;
$data=array();
$data['name']="wangwu";
$data['age']="11";
$collection->update($condition,$data);

//插入文档
$data=array();
$data['id']=4;
$data['name']="哈哈";
$data['age']="11";
$collection->insert($data);

//删除文档
$condition=array();
$condition['id']=2;
$collection->remove($condition);

//查询文档
$users=$collection->find();
foreach ($users as $k => $v) {
  print_r($v);
}
?>
