这篇文章主要介绍了php操作mongodb封装类与用法,结合具体实例形式分析了php定义的MongoDB操作封装类与相关的类实例化、查询、更新等使用技巧,需要的朋友可以参考下。 本文实例讲述了php操作mongodb封装类与用法，分享给大家供大家参考，具体如下： 近来学习了mongodb，刚好是做php开发的,随便写了php操作mongodb的封装类. <?php /** * Created by PhpStorm. * User: lee * Date: 2016/10/24 * Time: 13:49 */ namespace AppHttpControllersApi; use AppHttpCommonReturnApi; /* * * mongdb常规操作 */ class MongdbCommonController { private static $conn; private static $mon; private static $error; private function __construct(){ //self::$conn = new MongoClient("mongodb://".env('MONGDB_USER').":".env('MONGDB_PASS')."@".env('MONGDB_HOST').":".env('MONGDB_PORT')."/".env('MONGDB_DB')); self::$conn = new MongoClient("mongodb://".env('MONGDB_USER').":".env('MONGDB_PASS')."@".env('MONGDB_HOST').":".env('MONGDB_PORT')); //self::$conn = new MongoClient("mongodb://".env('MONGDB_HOST').":".env('MONGDB_PORT')); $db = env('MONGDB_DB'); self::$mon = self::$conn->$db; } public static function getInstance(){ if(!(self::$conn instanceof self)){ self::$conn = new self(); } //return self::$conn->mydb; return self::$conn; } private function __clone(){ trigger_error('Clone is not allowed'); }//禁止克隆 //创建索引 public function ensureIndex($table, $index, $index_param=array()) { $index_param['safe'] = 1; try { self::$mon->$table->ensureIndex($index, $index_param); return true; } catch (MongoCursorException $e) { self::$error = $e->getMessage(); return false; } } //添加 public function insert($table,$arr){ try { self::$mon->$table->insert($arr, array('w'=>true)); return true; } catch (MongoCursorException $e) { self::$error = $e->getMessage(); return false; } } //更新 public function update($table, $condition, $new_arr, $options=array()) { $options['w'] = 1; if (!isset($options['multiple'])) { $options['multiple'] = 0; } try { self::$mon->$table->update($condition, $new_arr, $options); return true; } catch (MongoCursorException $e) { self::$error = $e->getMessage(); return false; } } //删除 public function remove($table, $condition, $options=array()) { $options['w'] = 1; try { self::$mon->$table->remove($condition, $options); return true; } catch (MongoCursorException $e) { self::$error = $e->getMessage(); return false; } } //查找 public function find($table, $query_condition, $result_condition=array(), $fields=array()) { $cursor = self::$mon->$table->find($query_condition, $fields); if (!emptyempty($result_condition['start'])) { $cursor->skip($result_condition['start']); } if (!emptyempty($result_condition['limit'])) { $cursor->limit($result_condition['limit']); } if (!emptyempty($result_condition['sort'])) { $cursor->sort($result_condition['sort']); } $result = array(); try { while ($cursor->hasNext()) { $result[] = $cursor->getNext(); } } catch (MongoCursorTimeoutException $e) { self::$error = $e->getMessage(); return false; } return $result; } //查找一条记录 public function findOne($table, $condition, $fields=array()) { return self::$mon->$table->findOne($condition, $fields); } //返回表的记录数 public function count($table) { return self::$mon->$table->count(); } //返回错误信息 public function getError() { return self::$error; } } 操作实例： use AppHttpControllersApiMongdbCommonController; $db = MongdbCommonController::getInstance(); $collection = 'tab'; $data = array('tt' =>'sdsd', 'pp' => 'ssdsdf'); //返回记录数 echo $db->count($collection); //插入记录 $db->insert($collection, array("id"=>2, "title"=>"asdqw")); //更新 $db->update($collection, array("id"=>2),array('tt'=>'dfdfd',"gg"=>"bbb",'hh'=>'dfsdsd')); //查找记录 echo '<pre>'; print_r( $db->find($collection, array("tt"=>'dfdfd'), array("start"=>1,"limit"=>4))); //删除 $db->remove($collection, array('tt' =>'sdsd'));  （编辑：菏泽站长网） 【声明】本站内容均来自网络，其相关言论仅代表作者个人观点，不代表本站立场。若无意侵犯到您的权利，请及时与联系站长删除相关内容! |
