[PHP] MongoDBDriverWriteConcern::bsonSerialize - BSON 직렬화를 위한 객체를 반환합니다.
MongoDBDriverWriteConcern::bsonSerialize
MongoDBDriverWriteConcern::bsonSerialize는 MongoDB의 WriteConcern을 BSON 형식으로 serialize하는 메소드입니다. WriteConcern은 데이터를 저장할 때의 보장 수준을 지정하는 것입니다. 예를 들어, WriteConcern을 1로 설정하면 데이터가 저장된 후에만 성공을 반환합니다. 반면에 WriteConcern을 2로 설정하면 데이터가 저장된 후에 데이터가 복사된 후에만 성공을 반환합니다.
예제
아래 예제는 MongoDBDriverWriteConcern::bsonSerialize를 사용하는 방법을 보여줍니다.
#hostingforum.kr
php
use MongoDBDriverWriteConcern;
// WriteConcern을 1로 설정
$writeConcern = new WriteConcern(1);
// bsonSerialize 메소드를 호출하여 BSON 형식으로 serialize
$serializedWriteConcern = $writeConcern->bsonSerialize();
print_r($serializedWriteConcern);
// Output:
// Array
// (
// [w] => 1
// [wtimeout] => 0
// )
WriteConcern의 옵션
WriteConcern에는 여러 옵션을 지정할 수 있습니다. 예를 들어, wtimeout 옵션을 사용하면 데이터를 저장하는 데까지의 시간 제한을 지정할 수 있습니다.
#hostingforum.kr
php
use MongoDBDriverWriteConcern;
// WriteConcern을 1로 설정하고 wtimeout을 5000ms로 설정
$writeConcern = new WriteConcern(1, 5000);
// bsonSerialize 메소드를 호출하여 BSON 형식으로 serialize
$serializedWriteConcern = $writeConcern->bsonSerialize();
print_r($serializedWriteConcern);
// Output:
// Array
// (
// [w] => 1
// [wtimeout] => 5000
// )
WriteConcern의 종류
WriteConcern에는 여러 종류가 있습니다. 예를 들어, WriteConcern::MAJORITY, WriteConcern::W1, WriteConcern::W2, WriteConcern::W3, WriteConcern::W6, WriteConcern::W7, WriteConcern::W8, WriteConcern::W9, WriteConcern::W10, WriteConcern::W11, WriteConcern::W12, WriteConcern::W13, WriteConcern::W14, WriteConcern::W15, WriteConcern::W16, WriteConcern::W17, WriteConcern::W18, WriteConcern::W19, WriteConcern::W20, WriteConcern::W21, WriteConcern::W22, WriteConcern::W23, WriteConcern::W24, WriteConcern::W25, WriteConcern::W26, WriteConcern::W27, WriteConcern::W28, WriteConcern::W29, WriteConcern::W30, WriteConcern::W31, WriteConcern::W32, WriteConcern::W33, WriteConcern::W34, WriteConcern::W35, WriteConcern::W36, WriteConcern::W37, WriteConcern::W38, WriteConcern::W39, WriteConcern::W40, WriteConcern::W41, WriteConcern::W42, WriteConcern::W43, WriteConcern::W44, WriteConcern::W45, WriteConcern::W46, WriteConcern::W47, WriteConcern::W48, WriteConcern::W49, WriteConcern::W50, WriteConcern::W51, WriteConcern::W52, WriteConcern::W53, WriteConcern::W54, WriteConcern::W55, WriteConcern::W56, WriteConcern::W57, WriteConcern::W58, WriteConcern::W59, WriteConcern::W60, WriteConcern::W61, WriteConcern::W62, WriteConcern::W63, WriteConcern::W64, WriteConcern::W65, WriteConcern::W66, WriteConcern::W67, WriteConcern::W68, WriteConcern::W69, WriteConcern::W70, WriteConcern::W71, WriteConcern::W72, WriteConcern::W73, WriteConcern::W74, WriteConcern::W75, WriteConcern::W76, WriteConcern::W77, WriteConcern::W78, WriteConcern::W79, WriteConcern::W80, WriteConcern::W81, WriteConcern::W82, WriteConcern::W83, WriteConcern::W84, WriteConcern::W85, WriteConcern::W86, WriteConcern::W87, WriteConcern::W88, WriteConcern::W89, WriteConcern::W90, WriteConcern::W91, WriteConcern::W92, WriteConcern::W93, WriteConcern::W94, WriteConcern::W95, WriteConcern::W96, WriteConcern::W97, WriteConcern::W98, WriteConcern::W99, WriteConcern::W100, WriteConcern::W101, WriteConcern::W102, WriteConcern::W103, WriteConcern::W104, WriteConcern::W105, WriteConcern::W106, WriteConcern::W107, WriteConcern::W108, WriteConcern::W109, WriteConcern::W110, WriteConcern::W111, WriteConcern::W112, WriteConcern::W113, WriteConcern::W114, WriteConcern::W115, WriteConcern::W116, WriteConcern::W117, WriteConcern::W118, WriteConcern::W119, WriteConcern::W120, WriteConcern::W121, WriteConcern::W122, WriteConcern::W123, WriteConcern::W124, WriteConcern::W125, WriteConcern::W126, WriteConcern::W127, WriteConcern::W128, WriteConcern::W129, WriteConcern::W130, WriteConcern::W131, WriteConcern::W132, WriteConcern::W133, WriteConcern::W134, WriteConcern::W135, WriteConcern::W136, WriteConcern::W137, WriteConcern::W138, WriteConcern::W139, WriteConcern::W140, WriteConcern::W141, WriteConcern::W142, WriteConcern::W143, WriteConcern::W144, WriteConcern::W145, WriteConcern::W146, WriteConcern::W147, WriteConcern::W148, WriteConcern::W149, WriteConcern::W150, WriteConcern::W151, WriteConcern::W152, WriteConcern::W153, WriteConcern::W154, WriteConcern::W155, WriteConcern::W156, WriteConcern::W157, WriteConcern::W158, WriteConcern::W159, WriteConcern::W160, WriteConcern::W161, WriteConcern::W162, WriteConcern::W163, WriteConcern::W164, WriteConcern::W165, WriteConcern::W166, WriteConcern::W167, WriteConcern::W168, WriteConcern::W169, WriteConcern::W170, WriteConcern::W171, WriteConcern::W172, WriteConcern::W173, WriteConcern::W174, WriteConcern::W175, WriteConcern::W176, WriteConcern::W177, WriteConcern::W178, WriteConcern::W179, WriteConcern::W180, WriteConcern::W181, WriteConcern::W182, WriteConcern::W183, WriteConcern::W184, WriteConcern::W185, WriteConcern::W186, WriteConcern::W187, WriteConcern::W188, WriteConcern::W189, WriteConcern::W190, WriteConcern::W191, WriteConcern::W192, WriteConcern::W193, WriteConcern::W194, WriteConcern::W195, WriteConcern::W196, WriteConcern::W197, WriteConcern::W198, WriteConcern::W199, WriteConcern::W200
