Bug #74848 [NEW]: the parameter fields does not work

From: blackpanther dot online at gmx dot de Operating system: PHP version: 7.1.6 Package: mongodb Bug Type: Bug Bug description:the parameter fields does not work Description: ------------ --- From manual page: http://www.php.net/mongocollection.find --- If you pass the second parameter fields, you should receive only the fields given, but actually you receive all. You can pass ["field_a" => true] and get all fields. The same then you pass ["field_a" => false]. So it's not working. (If you check the mongodb's find method directly on the database without php by collection.find({},{"field_a":1}) it works properly) Test script: --------------- require '../vendor/autoload.php'; $mongodb = new MongoDB\Client("mongodb://xx:xx@localhost:27017/test"); // needs an existing mongodb server $collection = $mongodb->test->phpfind; // needs an existing database // create a new record $collection->insertOne(['field_a' => 'A', 'field_b' => 'B']); // should return a entry with only _id and field_a as fields print_r($collection->findOne([], ['field_a' => true])); // should return a entry with only _id and field_b as fields print_r($collection->findOne([], ['field_a' => false])); Expected result: ---------------- MongoDB\Model\BSONDocument Object ( [storage:ArrayObject:private] => Array ( [_id] => MongoDB\BSON\ObjectID Object ( [oid] => 595a4cd3a1b69920b0003641 ) [field_a] => A ) ) MongoDB\Model\BSONDocument Object ( [storage:ArrayObject:private] => Array ( [_id] => MongoDB\BSON\ObjectID Object ( [oid] => 595a4cd3a1b69920b0003641 ) [field_b] => B ) ) Actual result: -------------- MongoDB\Model\BSONDocument Object ( [storage:ArrayObject:private] => Array ( [_id] => MongoDB\BSON\ObjectID Object ( [oid] => 595a4cd3a1b69920b0003641 ) [field_a] => A [field_b] => B ) ) MongoDB\Model\BSONDocument Object ( [storage:ArrayObject:private] => Array ( [_id] => MongoDB\BSON\ObjectID Object ( [oid] => 595a4cd3a1b69920b0003641 ) [field_a] => A [field_b] => B ) ) -- Edit bug report at https://bugs.php.net/bug.php?id=74848&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=74848&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=74848&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=74848&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=74848&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=74848&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=74848&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=74848&r=needscript Try newer version: https://bugs.php.net/fix.php?id=74848&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=74848&r=support Expected behavior: https://bugs.php.net/fix.php?id=74848&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=74848&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=74848&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=74848&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=74848&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=74848&r=dst IIS Stability: https://bugs.php.net/fix.php?id=74848&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=74848&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=74848&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=74848&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=74848&r=mysqlcfg
