Description:
------------
---
From manual page: http://www.php.net/mongocollection.batchinsert
---

Now, we can use following option:
"PHP-233: Added the continueOnError flag to batch_insert()."

It insterts all documents, except one's that were excluded.

Test script:
---------------
$object = $db->selectCollection('c');
$object->drop();

$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'),
'id' => 3,
'desc' => "THREE",
);
$doc4 = array(
'_id' => new MongoId('4cb4ab6d7addf98506010004'),
'id' => 4,
'desc' => "FOUR",
);

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

Actual result:
--------------
array(3) {
["_id"]=>
object(MongoId)#%d (1) {
["$id"]=>
string(24) "4cb4ab6d7addf98506010001"
}
["id"]=>
int(1)
["desc"]=>
string(3) "ONE"
}
array(3) {
["_id"]=>
object(MongoId)#%d (1) {
["$id"]=>
string(24) "4cb4ab6d7addf98506010002"
}
["id"]=>
int(2)
["desc"]=>
string(3) "TWO"
}
array(3) {
["_id"]=>
object(MongoId)#%d (1) {
["$id"]=>
string(24) "4cb4ab6d7addf98506010004"
}
["id"]=>
int(4)
["desc"]=>
string(4) "FOUR"
}
