MongoCollection::batchInsert

(PECL mongo >=0.9.0)

MongoCollection::batchInsertInserts multiple documents into this collection

Opis

public mixed MongoCollection::batchInsert ( array $a [, array $options = array() ] )

Parametry

a

An array of arrays.

options

Options for the inserts.

  • "w"

    See WriteConcerns. The default value for MongoClient is 1.

  • "fsync"

    Boolean, defaults to FALSE. Forces the insert to be synced to disk before returning success. If TRUE, an acknowledged insert is implied and will override setting w to 0.

  • "timeout"

    Integer, defaults to MongoCursor::$timeout. If "safe" is set, this sets how long (in milliseconds) for the client to wait for a database response. If the database does not respond within the timeout period, a MongoCursorTimeoutException will be thrown.

  • "continueOnError"

    Boolean, defaults to FALSE. If set, the database will not stop processing a bulk insert if one fails (eg due to duplicate IDs). This makes bulk insert behave similarly to a series of single inserts, except that calling MongoDB::lastError() will have an error set if any insert fails, not just the last one. If multiple errors occur, only the most recent will be reported by MongoDB::lastError().

  • "safe"

    Deprecated. Please use the WriteConcern w option.

Zwracane wartości

If the w parameter is set to acknowledge the write, returns an associative array with the status of the inserts ("ok") and any error that may have occured ("err"). Otherwise, returns TRUE if the batch insert was successfully sent, FALSE otherwise.

Błędy/Wyjątki

Throws MongoCursorException if the "w" option is set and the write fails.

Throws MongoCursorTimeoutException if the "w" option is set to a value greater than one and the operation takes longer than MongoCursor::$timeout milliseconds to complete. This does not kill the operation on the server, it is a client-side timeout. The operation in MongoCollection::$wtimeout is milliseconds.

Przykład #1 MongoCollection::batchInsert() example

Batch insertion is a quick way to add many elements to the database at once

<?php

$users 
= array();
for (
$i 0$i<100$i++) {
  
$users[] = array('username' => 'user'.$i'i' => $i);
}

$mongo = new MongoClient();
$collection $mongo->my_db->users;
$collection->drop();

$collection->batchInsert($users);

foreach (
$users as $user) {
  echo 
$user['_id']."\n"// populated with instanceof MongoId
}

$users $collection->find()->sort(array('i' => 1));
foreach (
$users as $user) {
    
var_dump($user['username']);
}

?>

...
string(5) "user1"

Przykład #2 MongoCollection::batchInsert() example with ignoring errors

<?php

$con 
= new Mongo;
$db $con->demo;

$doc1 = array(
        
'_id' => new MongoId('4cb4ab6d7addf98506010001'),
        
'id' => 1,
        
'desc' => "ONE",
);
$doc2 = array(
        
'_id' => new MongoId('4cb4ab6d7addf98506010002'),
        
'id' => 2,
        
'desc' => "TWO",
);
$doc3 = array(
        
'_id' => new MongoId('4cb4ab6d7addf98506010002'), // same _id as above
        
'id' => 3,
        
'desc' => "THREE",
);
$doc4 = array(
        
'_id' => new MongoId('4cb4ab6d7addf98506010004'),
        
'id' => 4,
        
'desc' => "FOUR",
);

$c $db->selectCollection('c');
$c->batchInsert(
    array(
$doc1$doc2$doc3$doc4),
    array(
'continueOnError' => true)
);

$docs $c->find();
foreach (
$docs as $doc) {
    
var_dump($doc['desc']);
}
?>

string(4) "FOUR"
