PHP7之Mongodb API使用詳解

編譯安裝PHP7

編譯安裝PHP7 Mongdb擴展

#先安裝一個依賴庫yum -y install openldap-develwget https://pecl.php.net/get/mongodb-1.1.1.tgz /home/server/php7/bin/phpize #根據自己編譯的PHP環境而定./configure --with-php-config=/home/server/php7/bin/php-config make && make install#如果成功，生成一個mongodb.so擴展在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擴展，老的php-mongodb api
在PHP7已經不支持了，至少目前不支持。
最新支持PHP7的mongodb 編譯后僅支持新版API(mongodb > 2.6.X版本)

Mongodb API 操作

初始化Mongodb連接

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

查詢

$filter = array();$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);}
