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

<classname>MongoCursorException</classname> if the insert did not
|
|
succeed.

<para>

If <literal>safe</literal> 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.

<para>

Boolean, defaults to &false;. Forces the insert to be synced to

disk before returning success. If &true;, a safe insert is implied

|

<para>
|
|
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 <function>MongoDB::lastError</function>
|
|
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
|
|
<function>MongoDB::lastError</function>.

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
