一、连接数据库(在完成对MongoDB的扩展的前提下)
连接本地的mongodb，端口默认27017，
<?php
//连接Mongodb
$manager = new MongoDB\Driver\Manager("mongodb://127.0.0.1:27017");
echo "connect success!!!";
?>
二、插入数据
<?php
//连接Mongodb
$manager = new MongoDB\Driver\Manager("mongodb://127.0.0.1:27017");
echo "connect success!!!";
//创建变量，进行插入操作
$bulk = new MongoDB\Driver\BulkWrite;
//插入的数据(插入一条或多条)
$bulk->insert(["name"=>"zhangsan","age"=>25,"class"=>"jisuanjierban"]);
$bulk->insert(["name"=>"lisi","age"=>25,"class"=>"jisuanjisiban"]);
//插入数据到useinfo数据库下的student表
$manager->executeBulkWrite("useinfo.student",$bulk);
echo "insert success!!!";
?>
三、查询数据
<?php
//连接Mongodb
$manager = new MongoDB\Driver\Manager("mongodb://127.0.0.1:27017");
echo "connect success!!!".PHP_EOL;
//过滤条件
$filter = ['age' => ['$gt' => 20]];
//可选项
$option = [
'projection' => ["_id" =>0], //不显示_id,此字段用于指定显示或不显示某些字段
'sort' => ['name' => -1], //按照某些字段排序 ,-1倒叙，1正序
'limit'=>$pageSize, //取多少条数据
'skip' => ($num-1)*$pageSize //取第几页数据
];
//查询数据
$query = new MongoDB\Driver\Query($filter, $option);
//查询结果，返回数组
$cursor = $manager->executeQuery('useinfo.student',$query);
//循环遍历
foreach ($cursor as $document){
print_r($document);
}
echo "over";
?>
四、更新数据
<?php
//连接Mongodb
$manager = new MongoDB\Driver\Manager("mongodb://127.0.0.1:27017");
echo "connect success!!!"
$bulk->new MongoDB\Driver\BulkWrite;
$bulk->update(
["name" => "zhangsan"],
["$set" => ["name" => "kenan","class" => "softeneregy"]],
["multi" => false, "upsert" => false], //multi为true，代表更新找到的所有记录，false默认更新找到的第一条
//upsert为true代表如果没有此条记录就执行插入操作，默认false不插入
);
$result = $manager->executeBulkWrite('test.sites', $bulk);
?>
五、对以上方法进行简单的封装
<?php
class MongoDBClient{
protected $manager; //连接数据库
protected $dbname; //操作的数据库
protected $collection; //操作的数据库下的表
protected $bulk; // 插入和更新操作
protected $writeConcern; //连接超时
//定义构造函数
public function __construct($config){
$this->manager = new MongoDB\Driver\Manager("mongodb://127.0.0.1:27017"); //连接数据库
$this->dbname = $config["dbname"]; //初始化数据库
$this->collection = $config["collection"]; //初始化集合
$this->bulk = $new MongoDB\Driver\BulkWrite; //插入、更新操纵
$this->writeConcern = new MongoDB\Driver\WriteConcern(MongoDB\Driver\WriteConcern::MAJORITY,100); //连接超时
}
//查询方法
public function query($filter=[],$option=[]){
//创建查询对象
$query = new MongoDB\Driver\Query($filter,$option)
//查询结果，返回数组
$cursor = $manager->executeQuery("$this->dbname.$this->collection",$uery);
//循环遍历
foreach($cursor as $document){
print_r($document);
}
}
//插入数据
public function insert($data=[]){
//插入一条或多条数据 $bulk->insert(["name"=>"zhangsan","age"=>25,"class"=>"jisuanjierban"]);
$this->bulk->insert($data);
//插入数据到指定的数据库下的表
$this->manager->executeQuery("$this->dbname.$this->collection",$this->bulk);
}
//更新数据
public function update($filter=[],$update=[],$upsert=false){
$this->bulk->update([
$filter,
["$set" => $update],
["multi" => true,"upsert"=>$upsert],
]);
$result = $this->manager-executeBulkWrite("$this->dbname.$this->collection",$this-bulk);
}
//删除数据
public function delete($filter=[],$limit=0){
$this-bulk-delete(
$filter,
['limit' => $limit]
);
$result = $this->manager->exeucuteBulkWrite("$this->dbname.$this-colletion",$this-bulk);
}
}
//获取要操作的数据库
$dbname = $_GET['dbname'];
//要操作的表(集合)
$collection = $_GET['colection'];
//创建当前类的对象
$obj1 = new MongoDBClient(["dbname"=>$dbname,"collection"=>$collection]);
//从表单获取当前操作类型（增、删、改、查）
$action = $_GET['action'];
//插入数据
if($action == "insert"){
$data = $_GET["data"];
$obj1->insert($data);
//查询数据
}else if($action == "query"){
$filter = $_GET["filter"];
$option = $_GET["option"];
$obj->query($filter,$option);
}
//更新数据
else if($action == "update"){
$filter = $_GET["filter"];
$update = $_GET["date"];
$obj1->update($filter,$update);
}
//删除数据
else if($action == "delete"){
$filter = $_GET("filter");
$obj1->delete($filter);
}
?>
