(PECL mongo >=0.9.0)
MongoCollection::save — Saves an object to this collection
If the object is from the database, update the existing database object, otherwise insert this object.
Array to save.
Options for the save.
"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.
If safe was set, returns an array containing the status of the save. Otherwise, returns a boolean representing if the array was not empty (an empty array will not be inserted).
Throws MongoCursorException if the "safe" option is set and the save 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.
| Version | Description |
|---|---|
| 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. |
Example #1 MongoCollection::save() example
<?php
$obj = array('x' => 1);
// insert $obj into the db
$collection->save($obj);
// add another field
$obj['foo'] = 'bar';
// $obj cannot be inserted again, causes duplicate _id error
$collection->insert($obj);
// save updates $obj with the new field
$collection->save($obj);
?>
