mongodb+php實(shí)現(xiàn)簡單的增刪改查

windows上安裝mongodb的php擴(kuò)展

下載地址https://s3.amazonaws.com/drivers.mongodb.org/php/index.html

找到對(duì)應(yīng)的php版本的dll文件，下載php_mongo.dll，放到php安裝目錄下的ext目錄中，修改php.ini，添加一項(xiàng)extension=php_mongo.dll，沒有找到支持php7的dll

1. 獲取MongoClient對(duì)象，new出來
2. 獲取數(shù)據(jù)庫對(duì)象db，通過MongoClient對(duì)象的數(shù)據(jù)庫屬性，$MongoClient->數(shù)據(jù)庫名
3. 獲取集合collection，通過db對(duì)象的集合屬性，$db->集合名
4. 創(chuàng)建集合，調(diào)用db對(duì)象的createCollection()方法，
5. 調(diào)用collection對(duì)象的find()方法，查詢數(shù)據(jù)，$collection->find()
6. 調(diào)用collection對(duì)象的update ()方法，更新數(shù)據(jù)，$collection->update($condition,$data);
7. 調(diào)用collection對(duì)象的insert ()方法，插入數(shù)據(jù)，$collection->insert($data);

?php
// 連接到mongodb
$mongoClient = new MongoClient();
// 選擇一個(gè)數(shù)據(jù)庫
$db = $mongoClient->test;

//獲取集合
$collection=$db->users;

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

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

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

//查詢文檔
$users=$collection->find();
foreach ($users as $k => $v) {
  print_r($v);
}
