Beispiele

Beispiel #1 MongoDB\Driver\Manager::executeUpdate() example

<?php
$criteria 
= array(
    
"tag" => "mongodb",
);
$document = array(
    
'$set' => array(
        
"rating" => 5,
    ),
);
$updateOptions = array(
    
"multi" => true,
);
$writeConcern = new MongoDB\Driver\WriteConcern(MongoDB\Driver\WriteConcern::MAJORITY100);

$manager = new MongoDB\Driver\Manager("mongodb://localhost:27017");
$result $manager->executeUpdate("mydb.collection"$criteria$document$updateOptions$writeConcern);

printf("Updated %d document(s)\n"$result->getModifiedCount());
printf("Matched %d document(s)\n"$result->getMatchedCount());
printf("Upserted documents: %d\n"$result->getUpsertedCount());
foreach (
$result->getUpsertedIds() as $index => $id) {
    
printf("upsertedId[%d]: "$index);
    
var_dump($id);
}

/* If the WriteConcern could not be fulfilled */
if ($writeConcernError $result->getWriteConcernError()) {
    
printf("%s (%d): %s\n"$error->getMessage(), $error->getCode(), var_export($error->getInfo(), true));
}

/* If the write could not happen at all */
foreach ($result->getWriteErrors() as $writeError) {
    
printf("%s (%d)\n"$error->getMessage(), $error->getCode());
}
?>

Das oben gezeigte Beispiel erzeugt eine ähnliche Ausgabe wie:

Updated 0 document(s)
Matched 0 document(s)
Upserted documents: 0

Beispiel #2 MongoDB\Driver\Manager::executeUpdate() with upsert

<?php
$criteria 
= array(
    
"tag" => "mongodb",
);
$document = array(
    
'$set' => array(
        
"rating" => 5,
    ),
);
$updateOptions = array(
    
"multi" => false,
    
"upsert" => true,
);
$writeConcern = new MongoDB\Driver\WriteConcern(MongoDB\Driver\WriteConcern::MAJORITY100);

$manager = new MongoDB\Driver\Manager("mongodb://localhost:27017");
$result $manager->executeUpdate("mydb.collection"$criteria$document$updateOptions$writeConcern);

printf("Updated %d document(s)\n"$result->getModifiedCount());
printf("Matched %d document(s)\n"$result->getMatchedCount());
printf("Upserted documents: %d\n"$result->getUpsertedCount());
foreach (
$result->getUpsertedIds() as $index => $id) {
    
printf("upsertedId[%d]: "$index);
    
var_dump($id);
}

/* If the WriteConcern could not be fulfilled */
if ($writeConcernError $result->getWriteConcernError()) {
    
printf("%s (%d): %s\n"$writeConcernError->getMessage(), $writeConcernError->getCode(), var_export($writeConcernError->getInfo(), true));
}

/* If the write could not happen at all */
foreach ($result->getWriteErrors() as $writeError) {
    
printf("%s (%d)\n"$writeError->getMessage(), $writeError->getCode());
}
?>

Das oben gezeigte Beispiel erzeugt eine ähnliche Ausgabe wie:

Updated 0 document(s)
Matched 0 document(s)
Upserted documents: 1
upsertedId[0]: object(BSON\ObjectID)#3 (1) {
  ["oid"]=>
  string(24) "54d2c0d14c245fbe70d32ccf"
}

Anmerkungen

Hinweis:

On write failure, MongoDB\Driver\WriteResult::getWriteErrors() will only ever have one MongoDB\Driver\WriteError in the array, and MongoDB\Driver\WriteError::getIndex() will always be 0 (the index of this operation in the batch).

Hinweis:

MongoDB\Driver\WriteResult::getUpsertedIds() will only ever have one BSON\ObjectID in the array, and the index always be 0 (the index of this operation in the batch).
