Convert MongoDB object from updateOne into PHP array

Question

My output in PHP from a var_dump() shows the result of a updateOne MongoDB command to a collection:

object(MongoDB\UpdateResult)#136 (2) {  
    ["writeResult":"MongoDB\UpdateResult":private] => object(MongoDB\Driver\WriteResult)#135 (9) { 
        ["nInserted"]=> int(0) 
        ["nMatched"]=> int(0) 
        ["nModified"]=> int(0) 
        "nRemoved"]=> int(0) 
        ["nUpserted"]=> int(0) 
        ["upsertedIds"]=> array(0) { } 
        ["writeErrors"]=> array(0) { } 
        ["writeConcernError"]=> NULL 
        ["writeConcern"]=> array(4) { 
            ["w"]=> NULL 
            ["wmajority"]=> bool(false) 
            ["wtimeout"]=> int(0) 
            ["journal"]=> NULL 
        } 
    } 
    ["isAcknowledged":"MongoDB\UpdateResult":private]=> bool(true) 
}

My question is, how do I convert this into PHP and access the value for "nMatched" and "nInserted"?

According to mongodb.github.io/mongo-php-library/api/… there's a method called getMatchedCount to get the nMatched value, however there does not seem to be an equivalent one for nInserted, which probably makes sense since this is an UpdateResult and would only have modified values. — apokryfos

You can use the returned object directly. For accessing matched you can do:

$result->getMatchedCount();

adn for the inserted:

$result->getUpsertedCount();

This is the right and easiest way. You can use this as a reference http://mongodb.github.io/mongo-php-library/api/class-MongoDB.UpdateResult.html
