PHP7:Mongodb API usage

This article mainly introduces you to the use of PHP7:Mongodb API. I hope it will be helpful to friends in need!

Compile and install PHP7 Mongdb extension

#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/

Modify php.ini configuration

extension=mongodb.so

Note:

The previous version used mongo .so extension, the old php-mongodb api

is no longer supported in PHP7, at least not currently.

The latest mongodb that supports PHP7 only supports the new version of API after compilation (mongodb > 2.6.X version)

Mongodb API operation

Initialize Mongodb connection

$manager = new MongoDB\Driver\Manager("mongodb://127.0.0.1:27017"); var_dump($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 operation

$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());

Query

$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); }
