MongoCollection::batchInsert — Inserts multiple documents into this collection
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 journalling is enabled, it works exactly like "j". If journalling is not enabled, it 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.
Note:
This option is deprecated. Please use the "j" option instead.
"j"
Boolean, defaults to FALSE. Forces the insert to be synced to the journal before returning success. If TRUE, an acknowledged insert is implied and will override setting w to 0.
"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.
"safe"
Deprecated. Please use the WriteConcern w option.
"timeout"
Integer, defaults to MongoCursor::$timeout. If acknowledged writes are used, this sets how long (in milliseconds) for the client to wait for a database response. If the database does not respond within the timeout period, a MongoCursorTimeoutException will be thrown.
If the w parameter is set to acknowledge the write,
returns an associative array with the status of the inserts ("ok") and any
error that may have occurred ("err"). Otherwise, returns TRUE if the
batch insert was successfully sent, FALSE otherwise.
Throws MongoException if any inserted documents are empty or if they contains zero-length keys. Attempting to insert an object with protected and private properties will cause a zero-length key error.
Throws MongoCursorException if the "w" option is set and the write fails.
Throws MongoCursorTimeoutException if the "w" option is set to a value greater than one and the operation takes longer than MongoCursor::$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.
| Version | Description |
|---|---|
| 1.2.7 | Added "continueOnError" option. |
| 1.0.9 |
Added ability to pass integers to the "safe" option, which previously only accepted booleans. Added "fsync" option. |
| 1.0.5 | Added options parameter. |
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"
