前言
最近在做的項目需要將PHP5.6升級到PHP7.0，使用過PHP-mongo擴展的同學應該知道，PHP7.0的mongodb擴展是完全不兼容PHP5.6的mongo擴展的，php-mongodb改如何使用呢。
下面直接說明各種方法的使用:
1.mongodb連接：
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 $e){ return false; }}2.查詢find:
public function find($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 $e) { //記錄錯誤日志 } return false;}3.插入操作insert:
public function insert($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 $e) { //記錄錯誤日志 } return false;}4.刪除delete：
public function delete($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 $e) { //記錄錯誤日志 } return false;}5.執行command操作:
private function command($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 $e) { //記錄錯誤 } return false;}6.統計count:
public function count($query, $collection) { try { $cmd = array( 'count' => $collection, 'query' => $query, ); $res = $this->command($cmd); $result = $res->toArray(); return $result[0]->n; } catch (Exception $e) { //記錄錯誤 } return false;}7.聚合distinct:
public function distinct($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 $e) { //記錄錯誤 } return false;}8.aggregate操作：
public function aggregate($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) { //記錄錯誤 } return false;}總結
