Inserts multiple documents into this collection

说明

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

参数

a

An array of arrays.

options

Options for the inserts.

"safe"

Can be a boolean or integer, defaults to FALSE. If FALSE, the program continues executing without waiting for a database response. If TRUE, the program will wait for the database response and throw a MongoCursorException if the insert did not succeed.

If safe is an integer, will replicate the insert to that many machines before returning success (or throw an exception if the replication times out, see wtimeout). This overrides the w variable set on the collection.
"fsync"

Boolean, defaults to FALSE. Forces the insert to be synced to disk before returning success. If TRUE, a safe insert is implied and will override setting safe to FALSE.

返回值

If "safe" is set, 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.

错误/异常

Throws MongoCursorException if the "safe" option is set and the insert fails.

Throws MongoCursorTimeoutException if the "safe" option is set to a value greater than one and the database cannot replicate the operation in MongoCollection::$wtimeout milliseconds.

更新日志

版本	说明
1.0.5	Added "options" parameter.
1.0.9	Added ability to pass integers to "safe" options (only accepted booleans before) and added "fsync" option.

范例

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 Mongo();
$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']);
}

?>

以上例程的输出类似于：

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