MongoCollection::batchInsert

(PECL mongo >=0.9.0)

MongoCollection::batchInsertInserts multiple documents into this collection

Description

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

Parameters

a

An array of arrays or objects. If any objects are used, they may not have protected or private properties.

Note:

If the documents to insert do not have an _id key or property, a new MongoId instance will be created and assigned to it. See MongoCollection::insert() for additional information on this behavior.

options

Options for the inserts.

  • "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().

    Note:

    Please note that continueOnError affects errors on the database side only. If you try to insert a document that has errors (for example it contains a key with an empty name), then the document is not even transferred to the database as the driver detects this error and bails out. continueOnError has no effect on errors detected in the documents by the driver.

  • "fsync"

    Boolean, defaults to FALSE. If journaling is enabled, it works exactly like "j". If journaling is not enabled, the write operation blocks until it is synced to database files on disk. If TRUE, an acknowledged insert is implied and this option will override setting "w" to 0.

    Note: If journaling is enabled, users are strongly encouraged to use the "j" option instead of "fsync". Do not use "fsync" and "j" simultaneously, as that will result in an error.

  • "j"

    Boolean, defaults to FALSE. Forces the write operation to block until it is synced to the journal on disk. If TRUE, an acknowledged write is implied and this option will override setting "w" to 0.

    Note: If this option is used and journaling is disabled, MongoDB 2.6+ will raise an error and the write will fail; older server versions will simply ignore the option.

  • Integer, defaults to MongoCursor::$timeout. If acknowledged writes are used, 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.

    "socketTimeoutMS"

  • "w"

    See WriteConcerns. The default value for MongoClient is 1.

  • "wtimeout"

    How long to wait for WriteConcern acknowledgement. The default value for MongoClient is 10000 milliseconds.

    Warning

    Deprecated in favour of the "wTimeoutMS" option

  • "wTimeoutMS"

    How long to wait for WriteConcern acknowledgement. The default value for MongoClient is 10000 milliseconds.

  • "safe"

    Deprecated. Please use the WriteConcern w option.

  • "timeout"

    Integer, defaults to MongoCursor::$timeout. If acknowledged writes are used, 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.

    Warning

    Deprecated in favour of the "socketTimeoutMS" option

Return Values

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 occurred ("err"). Otherwise, returns TRUE if the batch insert was successfully sent, FALSE otherwise.

Errors/Exceptions

Throws MongoException if any inserted documents are empty or if they contains zero-length keys. Attempting to insert an object with protected and private properties will cause a zero-length key error.

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.

Changelog

Examples

Example #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']);
}

?>

The above example will output something similar to:

4bf43ac68ead0e1971000000
4bf43ac68ead0e1971010000
4bf43ac68ead0e1971020000
...
string(5) "user1"
string(5) "user2"
string(5) "user3"
...

Example #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']);
}
?>

The above example will output something similar to:

string(3) "ONE"
string(3) "TWO"
string(4) "FOUR"
