查找数据
$connectString = 'mongodb://127.0.0.1:27017/aka';
$manager = new MongoDB\Driver\Manager($connectString);
$filter = [hid=>1];
$options = array(
"projection" => array(
"hid" => 1,
"total" => 1,
),
"sort" => array(
"total" => -1,
),
"modifiers" => array(
'$comment' => "This is a query comment",
'$maxTimeMS' => 100,
),
"skip" => 2,
"limit" => 1,
);
$query = new MongoDB\Driver\Query($filter,$options);
$cursor = $manager->executeQuery("aka.test", $query);
var_dump($cursor->toArray());exit;
count统计
$connectString = 'mongodb://127.0.0.1:27017/aka';
$manager = new MongoDB\Driver\Manager($connectString);
$commands = [
'count' => "test",
'query' => [
//'hid'=>['$eq'=>1]
'hid'=>['$lt'=>3]
],
];
$command = new MongoDB\Driver\Command($commands);
$cursor = $manager->executeCommand("aka", $command);
var_dump($cursor->toArray());exit;
聚合查询
$connectString = 'mongodb://127.0.0.1:27017/aka';
$manager = new MongoDB\Driver\Manager($connectString);
$date = '2016-01-11';
$startime = $date. ' 00:00:00';
$endtime = $date. ' 23:59:59';
$commands = [
'aggregate' => "test",
'pipeline' =>[
['$match'=>['createtime'=>['$gte'=>$startime, '$lte' => $endtime]]],
['$group'=>['_id'=>'$hid','total'=>['$sum'=>'$total']]],
]
];
$command = new MongoDB\Driver\Command($commands);
try{
$cursor = $manager->executeCommand("aka", $command);
}catch(Exception $e){
//无法连接数据库 异常处理
echo "MongoDB Connection Error";exit;
}
$response = $cursor->toArray()[0]->result;
foreach($response as $v) {
echo $v->_id.':'.$v->total."\n";
}
数据插入|修改|删除
- 插入数据
$connectString = 'mongodb://127.0.0.1:27017/aka';
$manager = new MongoDB\Driver\Manager($connectString);
$bulk = new MongoDB\Driver\BulkWrite(['ordered' => true]);//顺序or并行发送到服务器执行
$bulk->insert(
['id' => 3, 'total'=> 5]
);
$bulk->insert(
['id' => 4, 'total'=> 8]
);
$writeConcern = new MongoDB\Driver\WriteConcern(MongoDB\Driver\WriteConcern::MAJORITY, 1000);
$result = $manager->executeBulkWrite('aka.test', $bulk, $writeConcern);
var_dump($result);
- 修改数据
$connectString = 'mongodb://127.0.0.1:27017/aka';
$manager = new MongoDB\Driver\Manager($connectString);
$bulk = new MongoDB\Driver\BulkWrite(['ordered' => true]);//顺序or并行发送到服务器执行
$bulk->update(
['hid' => 3],
['$set' => ['total' => 1000]],
['multi' => true, 'upsert' => true] //multi多个结果修改,upsert如果不存在就插入
);
$writeConcern = new MongoDB\Driver\WriteConcern(MongoDB\Driver\WriteConcern::MAJORITY, 1000);
$result = $manager->executeBulkWrite('aka.test', $bulk, $writeConcern);
var_dump($result);
- 删除数据
$connectString = 'mongodb://127.0.0.1:27017/aka';
$manager = new MongoDB\Driver\Manager($connectString);
$bulk = new MongoDB\Driver\BulkWrite(['ordered' => true]);//顺序or并行发送到服务器执行
$bulk->delete(['hid'=>1]);
$writeConcern = new MongoDB\Driver\WriteConcern(MongoDB\Driver\WriteConcern::MAJORITY, 1000);
$result = $manager->executeBulkWrite('aka.test', $bulk, $writeConcern);
var_dump($result);
增删改查可以放在一起
$connectString = 'mongodb://127.0.0.1:27017/aka';
$manager = new MongoDB\Driver\Manager($connectString);
$bulk = new MongoDB\Driver\BulkWrite(['ordered' => true]);//true顺序 false 并行发送到服务器执行
$bulk->insert(
['hid' => 3, 'total'=> 5]
);
$bulk->insert(
['hid' => 4, 'total'=> 8]
);
$bulk->update(
['hid' => 3],
['$set' => ['total' => 1000]],
['multi' => true, 'upsert' => true] //multi多个结果修改,upsert如果不存在就插入
);
$bulk->delete(['hid'=>1]);
$writeConcern = new MongoDB\Driver\WriteConcern(MongoDB\Driver\WriteConcern::MAJORITY, 1000);
$result = $manager->executeBulkWrite('aka.test', $bulk, $writeConcern);
var_dump($result);
