php操作mongodb基础语法

一、插入数据

<?php
    
    //连接Mongodb
    $manager = new MongoDBDriverManager("mongodb://127.0.0.1:27017");
    
    echo "connect success!!!";
    
    //创建变量，进行插入操作
    $bulk = new MongoDBDriverBulkWrite;
    
    //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!!!";
?>

二、查询数据

<?php
 
    //连接Mongodb
    $manager = new MongoDBDriverManager("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
    $query = new MongoDBDriverQuery($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";
    
?>

三、更新数据

//更新数据
<?php 
    //连接Mongodb
    $manager = new MongoDBDriverManager("mongodb://127.0.0.1:27017");
    
    echo "connect success!!!"
    
    $bulk->new MongoDBDriverBulkWrite;
    $bulk->update(
        ["name" => "zhangsan"],   //过滤条件
        ["$set" => ["name" => "kenan","class" => "softeneregy"]], //更新数据
        ["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
    );
    //执行更新操作
    $result = $manager->executeBulkWrite('test.sites', $bulk);
?>
