My data like this:
Array
(
[_id] => MongoId Object
(
[$id] => 51a6fca3f348aca011000000
)
[first_name] => Phan
[last_name] => Chuong
[interests] => Array
(
[0] => football
[1] => swimming
[2] => PHP
[3] => music
)
)
I want edit value PHP to PHP1 or set PHP to null. Please help me how can i do it? Thanks all!
You could use the MongoCollection::update() method like this:
// $c is your MongoCollection Object
$updatedata = array('$set' => array("interests.2" => "PHP1"));
$id = new MongoID('51a6fca3f348aca011000000')
$c->update(array("_id" => $id), $updatedata);
The update method needs two arrays, the first one will tell the DB which Object to update ( In this example where id = our id, always use the MongoID Object, always!), the second array defines what to update, note that you can get to values in nested arrays wit the dot like above. $set is an Field Update Operator, read more on them here: http://docs.mongodb.org/manual/reference/operator/update-field/
Or you could just get the entire Array, change it, and save it back.
$cursor = $c findOne("_id",4cb30f560107ae9813000000);
$cursor['interests'][2] = 'whatever';
$c->update($cursor);
