용법

새 연결 설정

 use ArangoDB  Connection  Connection ;

// Set a new Connection
$ connection = new Connection ([
    ' endpoint ' => ' http://yourarangohost:8529 ' ,
    ' username ' => ' YourUserName ' ,
    ' password ' => ' YourSecretPasswd ' ,
    ' database ' => ' YourDatabase ' ,
]);

// Alternatively, you can set a host and a port to connect
$ connection = new Connection ([
    ' host ' => ' http://yourarangohost ' ,
    ' port ' => 8529 ,
    ' username ' => ' YourUserName ' ,
    ' password ' => ' YourSecretPasswd ' ,
    ' database ' => ' YourDatabase ' ,
]);

// Or set more custom options like 'connection' type and timeout
$ connection = new Connection ([
    ' host ' => ' http://yourarangohost ' ,
    ' port ' => 8529 ,
    ' username ' => ' YourUserName ' ,
    ' password ' => ' YourSecretPasswd ' ,
    ' database ' => ' YourDatabase ' ,
    ' connection ' => ' Keep-Alive ' ,
    ' timeout ' => 30
]);

데이터베이스 관리

연결하면 이미 데이터베이스가 설정되어 있습니다. 데이터베이스 인스턴스를 얻을 수 있습니다.

 use ArangoDB  Database  Database ;
use ArangoDB  Collection  Collection ;
use ArangoDB  Connection  Connection ;

// Set up a connection
$ connection = new Connection ([
    ' host ' => ' http://yourarangohost ' ,
    ' port ' => 8529 ,
    ' username ' => ' YourUserName ' ,
    ' password ' => ' YourSecretPasswd ' ,
    ' database ' => ' YourDatabase ' ,
]);

$ database = $ connection -> getDatabase ();

// With a database object, we can retrieve information about it.
$ infoAboutCurrentDatabase = $ database -> getInfo ();

// Check if the database has a collection
if ( $ database -> hasCollection ( ' my_collection_name ' )){
    echo " Collection exists! " ;
} else {
    echo " Collection doesn't exist " ; 
}

// We can also create collections in the database
$ collection = $ database -> createCollection ( ' my_new_colletion ' );

// Or retrieve existing collections
$ collection = $ database -> getCollection ( ' my_existing_collection ' );

// With the Database class we can create and drop databases

// Lists the databases on the server
$ dbList = Database:: list ( $ connection );

// You can create a new database using the existing connection
$ result = Database:: create ( $ connection , ' my_database_name ' );

// And drop databases
$ result = Database:: drop ( $ connection , ' db_to_drop ' );

컬렉션

컬렉션 개체로 직접 작업할 수도 있습니다.

 use ArangoDB  Collection  Collection ;
use ArangoDB  Connection  Connection ;

$ connection = new Connection ([
    ' host ' => ' http://yourarangohost ' ,
    ' port ' => 8529 ,
    ' username ' => ' YourUserName ' ,
    ' password ' => ' YourSecretPasswd ' ,
    ' database ' => ' YourDatabase ' ,
    ' connection ' => ' Keep-Alive ' ,
    ' timeout ' => 30
]);

$ database = $ connection -> getDatabase ();

// If a collection exists on a database, the object will represent it.
$ collection = new Collection ( ' my_collection_name ' , $ database );

// If the collection does not exist, you can create it with the method 'save'
$ collection -> save ();

// Get all documents from the collection
foreach ( $ collection -> all () as $ document ){
    // Do something.
}

서류

 use ArangoDB  Document  Document ;
use ArangoDB  Connection  Connection ;

// Set up a connection
$ connection = new Connection ([
    ' host ' => ' http://yourarangohost ' ,
    ' port ' => 8529 ,
    ' username ' => ' YourUserName ' ,
    ' password ' => ' YourSecretPasswd ' ,
    ' database ' => ' YourDatabase ' ,
]);

// Check if the database has a collection called 'awesome_bands'. If not, create it.
$ db = $ connection -> getDatabase ();
if (! $ db -> hasCollection ( ' awesome_bands ' )) {
    $ db -> createCollection ( ' awesome_bands ' );
}

// Get the collection object
$ collection = $ db -> getCollection ( ' awesome_bands ' );

$ documentAttributes = [
    ' band ' => ' Quiet Riot ' ,
    ' members ' => [
        ' Kevin DuBrow ' ,
        ' Rudy Sarzo ' ,
        ' Carlos Cavazo ' ,
        ' Frankie Banali '
    ],
    ' active_since ' => 1975 ,
    ' city ' => ' Los Angeles ' ,
    ' country ' => ' USA '
];

// Create the document object
$ document = new Document ( $ documentAttributes , $ collection );

// Save the document on collection.
$ document -> save ();

// Add or change document attributes to update the document
$ document -> status = ' active ' ;
$ document -> save (); // Will update your document on server;

// Delete the document from the collection.
$ document -> delete ();

업무

JavaScript 코드를 보내는 ArangoDB 서버에서 트랜잭션을 수행할 수 있습니다.

 use ArangoDB  Exceptions  TransactionException ;
use ArangoDB  Transaction  JavascriptTransaction ;

// Define collections to perform write and read operations.
$ options = [
    ' collections ' => [
        ' read ' => [
            ' fighter_jets '
        ],
        ' write ' => [
            ' fighter_jets '
        ]
    ]
];

// Your JS action to execute.
$ action = " function(){ var db = require('@arangodb').db; db.fighter_jets.save({});  return db.fighter_jets.count(); } " ;

try {
    $ transaction = new JavascriptTransaction ( $ this -> getConnectionObject (), $ action , $ options );
    $ result = $ transaction -> execute (); // Will return 1.
} catch ( TransactionException $ transactionException ) {
    // Throws a TransactionException in case of error.
    return $ transactionException -> getMessage ();
}

PHP에서 직접 트랜잭션을 수행할 수도 있습니다.

 use ArangoDB  Document  Document ;
use ArangoDB  Connection  Connection ;
use ArangoDB  Transaction  StreamTransaction as Transaction ;

$ connection = new Connection ([
    ' host ' => ' http://yourarangohost ' ,
    ' port ' => 8529 ,
    ' username ' => ' YourUserName ' ,
    ' password ' => ' YourSecretPasswd ' ,
    ' database ' => ' YourDatabase ' ,
]);

$ db = $ connection -> getDatabase ();
if (! $ db -> hasCollection ( ' fighter_jets ' )) {
    $ db -> createCollection ( ' fighter_jets ' );
}

// Define collections to perform write and read operations.
$ options = [
    ' collections ' => [
        ' write ' => [
            ' fighter_jets '
        ]
    ]
];

// Declare a new transaction.
$ transaction = new Transaction ( $ connection , $ options );

try {
    // Start transaction.
    $ transaction -> begin ();

    // Do something
    $ collection = $ db -> getCollection ( ' fighter_jets ' );
    $ viper = new Document ([ ' model ' => ' F-16 Viper ' , ' status ' => ' In service ' , ' origin ' => ' USA ' ], $ collection );
    $ gripen = new Document ([ ' model ' => ' JAS 39 Gripen ' , ' status ' => ' In service ' , ' origin ' => ' Sweden ' ], $ collection );

    $ viper -> save ();
    $ gripen -> save ();

    // Commit the operations.
    $ transaction -> commit ();
} catch (  Exception $ exception ) {
    // Some error occurred. Abort transaction.
    $ transaction -> abort ();
}
