PHP7之Mongodb API使用详解

编译安装PHP7 Mongdb扩展

#先安装一个依赖库yum -y install openldap-develwget 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=https://www.jb51.net/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);}
