PHP7 mongoDB扩展使用的方法分享

前言

最近在做的项目需要将php5.6升级到php7.0，使用过php-mongo扩展的同学应该知道，php7.0的mongodb扩展是完全不兼容php5.6的mongo扩展的，php-mongodb改如何使用呢。

下面直接说明各种方法的使用:

1.mongodb连接：

private function connect($confarr) {
 try{
  $connstr = "mongodb://" . $confarr['host'] . ":" . $confarr['port'] . "/" . $confarr['db_name'];
  $options = array(
   'username' => $confarr['username'],
   'password' => $confarr['password'],
   'readpreference' => $confarr['read_preference'],
   'connecttimeoutms' => intval($confarr['connect_timeout_ms']),
   'sockettimeoutms' => intval($confarr['socket_timeout_ms']),
  );
  $mc = new mongodb\driver\manager($connstr, $options);
  return $mc;
 }
 catch(exception $e){
  return false;
 }
}

2.查询find:

public function find($query = array(), $fields = array(), $collection, $sort = array(), $limit = 0, $skip = 0) {
 $conn = $this->connect();
 if (empty($conn)) {
  return false;
 }
 try {
  $data = array();
  $options = array();
  if (!empty($query)) {
   $options['projection'] = array_fill_keys($fields, 1);
  }
  if (!empty($sort)) {
   $options['sort'] = $sort;
  }
  if (!empty($limit)) {
   $options['skip'] = $skip;
   $options['limit'] = $limit;
  }
  $mongoquery = new mongodb\driver\query($query, $options);
  $readpreference = new mongodb\driver\readpreference(mongodb\driver\readpreference::rp_secondary);
  $cursor = $conn->executequery($collection, $mongoquery, $readpreference);
  foreach($cursor as $value) {
   $data[] = (array)$value;
  }
  return $data;
 } catch (exception $e) {
  //记录错误日志
 }
 return false;
}

3.插入操作insert:

public function insert($addarr, $collection) {
 if (empty($addarr) || !is_array($addarr)) {
  return false;
 }
 $conn = $this->connect();
 if (empty($conn)) {
  return false;
 }
 try {
  $bulk = new mongodb\driver\bulkwrite();
  $bulk->insert($addarr);
  $writeconcern = new mongodb\driver\writeconcern(mongodb\driver\writeconcern::majority, 6000);
  $result = $conn->executebulkwrite($collection, $bulk, $writeconcern);
  if ($result->getinsertedcount()) {
   return true;
  }
 } catch (exception $e) {
  //记录错误日志
 }
 return false;
}

4.删除delete：

public function delete($wherearr, $options = array(), $collection) {
 if (empty($wherearr)) {
  return false;
 }
 if (!isset($options['justone'])) {
  $options = array(
   'justone' => false,
  );
 }
 $conn = $this->connect();
 if (empty($conn)) {
  return false;
 }
 try {
  $bulk = new mongodb\driver\bulkwrite();
  $bulk->delete($wherearr, $options);
  $writeconcern = new mongodb\driver\writeconcern(mongodb\driver\writeconcern::majority, 30000);
  $result = $conn->executebulkwrite($collection, $bulk, $writeconcern);
  return true;
 } catch (exception $e) {
  //记录错误日志
 }
 return false;
}

5.执行command操作:

private function command($params, $dbname) {
 $conn = $this->connect();
 if (empty($conn)) {
  return false;
 }
 try {
  $cmd = new mongodb\driver\command($params);
  $result = $conn->executecommand($dbname, $cmd);
  return $result;
 } catch (exception $e) {
  //记录错误
 }
 return false;
}

6.统计count:

public function count($query, $collection) {
 try {
  $cmd = array(
   'count' => $collection,
   'query' => $query,
  );
  $res = $this->command($cmd);
  $result = $res->toarray();
  return $result[0]->n;
 } catch (exception $e) {
  //记录错误
 }
 return false;
}

7.聚合distinct:

public function distinct($key, $where, $collection) {
 try {
  $cmd = array(
   'distinct' => $collection,
   'key' => $key,
   'query' => $where,
  );
  $res = $this->command($cmd);
  $result = $res->toarray();
  return $result[0]->values;
 } catch (exception $e) {
  //记录错误
 }
 return false;
}

8.aggregate操作：

public function aggregate($where, $group, $collection) {
 try {
  $cmd = array(
   'aggregate' => $collection,
   'pipeline' => array(
    array(
     '$match' => $where,
    ),
    array(
     '$group' => $group,
    ),
   ),
   'explain' => false,
  );
  $res = $this->command($cmd);
  if (!$res) {
   return false;
  }
  $result = $res->toarray();
  return $result[0]->total;
 } catch (exception $e) {
  //记录错误
 }
 return false;
}
