PHP7:Mongodb API使用

编译安装PHP7 Mongdb扩展

#先安装一个依赖库 yum -y install openldap-devel wget https://pecl.php.net/get/mongodb-1.1.1.tgz /home/server/php7/bin/phpize   #根据自己编译的PHP环境而定 ./configure --with-php-config=/home/server/php7/bin/php-config  make && make install #如果成功，生成一个mongodb.so扩展在lib/php/extensions/no-debug-non-zts-20151012/

修改php.ini配置

extension=mongodb.so

注：

以前版本用的是mongo.so扩展，老的php-mongodb api

在PHP7已经不支持了，至少目前不支持。

最新支持PHP7的mongodb 编译后 仅支持新版API(mongodb > 2.6.X版本)

Mongodb API 操作

初始化Mongodb连接

$manager =  new MongoDB\Driver\Manager("mongodb://127.0.0.1:27017");  var_dump($manager);   object(MongoDB\Driver\Manager)#1 (3) {   ["request_id"]=>   int(1714636915)   ["uri"]=>   string(25) "mongodb://localhost:27017"   ["cluster"]=>   array(13) {     ["mode"]=>     string(6) "direct"     ["state"]=>     string(4) "born"     ["request_id"]=>     int(0)     ["sockettimeoutms"]=>     int(300000)     ["last_reconnect"]=>     int(0)     ["uri"]=>     string(25) "mongodb://localhost:27017"     ["requires_auth"]=>     int(0)     ["nodes"]=>     array(...)     ["max_bson_size"]=>     int(16777216)     ["max_msg_size"]=>     int(50331648)     ["sec_latency_ms"]=>     int(15)     ["peers"]=>     array(0) {     }     ["replSet"]=>     NULL   } }

CURL操作

$bulk = new MongoDB\Driver\BulkWrite(['ordered' => true]); $bulk->delete([]); $bulk->insert(['_id' => 1]); $bulk->insert(['_id' => 2]); $bulk->insert(['_id' => 3, 'hello' => 'world']); $bulk->update(['_id' => 3], ['$set' => ['hello' => 'earth']]); $bulk->insert(['_id' => 4, 'hello' => 'pluto']); $bulk->update(['_id' => 4], ['$set' => ['hello' => 'moon']]); $bulk->insert(['_id' => 3]); $bulk->insert(['_id' => 4]); $bulk->insert(['_id' => 5]); $manager = new MongoDB\Driver\Manager('mongodb://localhost:27017'); $writeConcern = new MongoDB\Driver\WriteConcern(MongoDB\Driver\WriteConcern::MAJORITY, 1000); try {     $result = $manager->executeBulkWrite('db.collection', $bulk, $writeConcern); } catch (MongoDB\Driver\Exception\BulkWriteException $e) {     $result = $e->getWriteResult();     // Check if the write concern could not be fulfilled     if ($writeConcernError = $result->getWriteConcernError()) {         printf("%s (%d): %s\n",             $writeConcernError->getMessage(),             $writeConcernError->getCode(),             var_export($writeConcernError->getInfo(), true)         );     }     // Check if any write operations did not complete at all     foreach ($result->getWriteErrors() as $writeError) {         printf("Operation#%d: %s (%d)\n",             $writeError->getIndex(),             $writeError->getMessage(),             $writeError->getCode()         );     } } catch (MongoDB\Driver\Exception\Exception $e) {     printf("Other error: %s\n", $e->getMessage());     exit; } printf("Inserted %d document(s)\n", $result->getInsertedCount()); printf("Updated  %d document(s)\n", $result->getModifiedCount());

查询

$filter = array(); $options = array(     /* Only return the following fields in the matching documents */     "projection" => array(         "title" => 1,         "article" => 1,     ),     "sort" => array(         "views" => -1,     ),     "modifiers" => array(         '$comment'   => "This is a query comment",         '$maxTimeMS' => 100,     ), ); $query = new MongoDB\Driver\Query($filter, $options); $manager = new MongoDB\Driver\Manager("mongodb://localhost:27017"); $readPreference = new MongoDB\Driver\ReadPreference(MongoDB\Driver\ReadPreference::RP_PRIMARY); $cursor = $manager->executeQuery("databaseName.collectionName", $query, $readPreference); foreach($cursor as $document) {     var_dump($document); }
