脚本宝典收集整理的这篇文章主要介绍了php操作mongodb封装类与用法实例，脚本宝典觉得挺不错的，现在分享给大家，也给大家做个参考。
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 App\Http\Controllers\Api; use App\Http\Common\ReturnApi; /* * * 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, $fields); if (!empty($result_condition['start'])) { $cursor->skip($result_condition['start']); } if (!empty($result_condition['limit'])) { $cursor->limit($result_condition['limit']); } if (!empty($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 App\Http\Controllers\Api\MongdbCommonController;
$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'));
