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(   'urname' => $confarr['urname'],   '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 fal; }}

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 fal; } 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_condary);  $cursor = $conn->executequery($collection, $m山大威海分校ongoquery, $readpreference);  foreach($cursor as $value) {   $data[] = (array)$value;  }  return $data; } catch (exception $e) {  //记录错误日志 } return fal;}

3.插入操作inrt:

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

4.删除delete：

public function delete($wherearr, $options = array(), $collection) { if (empty($wherearr)) {  return fal; } if (!ist($options['justone'])) {  $options = array(   'justone' => fal,  ); } $conn = $this->connect(); if (empty($conn)) {  return fal; } 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 fal;}

5.执行command操作:

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

6.统计count:

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

7.聚合distinct:

public function distinct($key, $where, $collection) { try {  $cmd =湖南农业大学专业 array(   'distinct' => $collection,   'key' => $key,   'query' => $where,  );  $res = $this->command($cmd);  $result = $水的熔点res->toarray();  return $result[0]->values; } catch (exception $e) {  //记录错误 } return fal;}

8.aggregate操作：

public function aggregate($where, $group, $collection) { try {  $cmd = array(   'aggregate' => $collection,   'pipeline' => array(    array(     '$match' => $where,    ),    array(     '$group' => $group,    ),   ),   'explain' => fal,  );  $res = $this->command($cmd);  if (!$res作文我和神笔马良的一天) {   return fal;  }  $result = $res->toarray();  return $result[0]->total; } catch (exception $e) {  //记录错误 } return fal;}
