Expected "writeConcern" option to have type "MongoDB\Driver\WriteConcern" but found "array" about mongo-php-driver HOT 13 CLOSED

Can you paste your example code?

It looks like you might be doing $collection->insertOne($document, $options); where $options["writeConcern"] is not an instance of MongoDB\Driver\WriteConcern

from mongo-php-driver.

oh, sorry.

/** @var MongoDB\Collection $collection */
$collection->insertOne([
    'foo' => 'bar',
]);

from mongo-php-driver.

I've created MongoDB\Collection with $writeConcern = null.
Below I see $this->writeConcern = $writeConcern ?: $this->manager->getWriteConcern();
var_dump($this->manager->getWriteConcern()) in vendor/mongodb/mongodb/src/Collection.php:69 shows

array(4) { ["wmajority"]=> bool(false) ["wtimeout"]=> int(0) ["fsync"]=> NULL ["journal"]=> NULL }

from mongo-php-driver.

My mongodb.so was built from PHP7 branch of this repo, because I'm using php7

from mongo-php-driver.

The var_dump will call the debug handler on the object, which is why you see it as array.
If you do

$wc = $this->manager->getWriteConcern();
var_dump(get_class($wc), $wc);

it should print out MongoDB\Driver\WriteConcern

from mongo-php-driver.

I got 'Warning: get_class() expects parameter 1 to be object, array given'

from mongo-php-driver.

heh. uhm.. OK.... thats weird!

from mongo-php-driver.

Can you try this for me:

$ php -r '$manager = new MongoDB\Driver\Manager("mongodb://localhost:27017");  $wc = $manager->getWriteConcern(); var_dump($wc);'

I get the following:

object(MongoDB\Driver\WriteConcern)#2 (4) {
  ["w"]=>
  NULL
  ["wmajority"]=>
  bool(false)
  ["wtimeout"]=>
  int(0)
  ["journal"]=>
  NULL
}

from mongo-php-driver.

 php -v && php -r '$manager = new MongoDB\Driver\Manager("mongodb://localhost:27017");  $wc = $manager->getWriteConcern(); var_dump($wc);'

Ahhh. Found it.
You are using the PHP7 branch. It is no longer the most-up-2-date. @jmikola has a PR that is the latest version -- not entirely sure why its not merged into the branch or the branch deleted..

Using his PR it works for me (tm).

See: #136

from mongo-php-driver.

I've said it earlier: #153 (comment) :-)
Ok, thx, I'll be watch for progress.

from mongo-php-driver.

Yeah, sorry. I mistakenly read it as if you were using @jmikola PHP7 branch, as thats what I was using hehe. Sorry :)

from mongo-php-driver.

#175 (PHP 7 support) has been merged to master, so I think this can be closed. We should have a release with those changes out in a day or two. Feel free to re-open if that's not the case.
