$collection->find(); bson error, new Query() fails about mongo-php-library

[bjori]

What do you mean "silently fails"?
Does PHP just stop execution and nothing happen? That'd indicate it segfaults..

Code example:

<?php
    ini_set("display_errors",1);
    require_once 'vendor/autoload.php'; // include Composer goodies
    $manager = new MongoDB\Driver\Manager("mongodb://localhost:27017");
    $collection = new MongoDB\Collection($manager, "my_db.my_table");
    //$result = $collection->insertOne( [ 'name' => 'Hinterland', 'brewery' => 'BrewDog' ] );
    $cursor = $collection->find([ 'name' => 'Hinterland']); 
        echo "Searching for citizen => Iceland, verify Hayley is now Icelandic\n";
        foreach($cursor as $document) {
            var_dump($document);
        }
?>

Can you run the example in debug mode?
For example, say the PHP code above is in the filename example.php you'd run:

php -dmongodb.debug=stderr example.php

This would print out a lot of debug information.
If you could save it all to a file and upload/paste it here, it would help a lot, thanks!

As I see $options is invalid, $query = new Query($filter, $options),
because when I do $query = new Query($filter) it works.

Output from $options:

Array
(
    [allowPartialResults] =>
    [batchSize] => 101
    [comment] =>
    [cursorType] => 0
    [limit] => 0
    [maxTimeMS] => 0
    [modifiers] => Array
        (
        )

    [noCursorTimeout] =>
    [oplogReplay] =>
    [projection] => Array
        (
        )

    [skip] => 0
    [sort] => Array
        (
        )

    [cursorFlags] => 0
)

I'm having the exact same problem with 0.2.0 of the library.

    "mongodb/mongodb": "^0.2.0"

mongodb

mongodb support => enabled
mongodb version => 1.0.1
mongodb stability => stable
libmongoc version => 1.2.0
libbson version => 1.2.0

Directive => Local Value => Master Value
mongodb.debug => no value => no value

I tried commenting out all of the variables returned by getFindOptions() method one by one, and re-running my Find(), but it still failed. As the OP said, if you modify _buildQuery to remove passing in the $options array, things succeed.

If I upgraded to v1.0.0-beta1, the problem went away.

Using > db.version() 3.0.7

Sorry for the lack of updates here.

I'm pretty sure this is fixed in the latest pecl/mongodb release, 1.1.0.

Could you confirm?

1.1.1 is also being released any moment now with PHP7 support, if you'd like to wait and try that out -- it has rewritten lot of this code path to simplify certain things.

Closing this out due to inactivity. Please follow-up if the issue still persists in the more recent releases of the library and driver (1.1.1 is the latest and includes PHP 7 support, and we should have a 1.1.2 release out soon).
