问题 I'm getting the following error when using MongoDB's aggregate() function in a PHP code. This code perfectly works on my local setup which is running MongoDB 2.2.3 PHP Fatal error: Call to undefined method MongoCollection::aggregate() in /app/www/page.php on line 52, referer: http://referrer.url Code foreach($cats as $key=>$val){ $cats2[$val['lable']] = $myCollection->aggregate( array( array('$match' => array('user_id' => $user_id )), array('$unwind' =>"\$data"), array('$match' => array('data

问题 Here is my PHP code, it's getting a listing of collections from mongodb $list = $db->dbname->listCollections(); $result = array(); $i=0; foreach ($list as $thiscollection) { $result[$i++] = $thiscollection->getName(); } echo json_encode( $result ); I do console.log in the callback and this is what I see.

问题 I am developing a PHP web application using a MongoDB replicaset to store my data. I occasionally receive the following error: Fatal error: Uncaught exception 'MongoConnectionException' with message 'No candidate servers found' I have a 3 member Mongo replica set with 1 arbiter rs0:PRIMARY> rs.status() { "set" : "rs0", "date" : ISODate("2013-01-30T01:04:04Z"), "myState" : 1, "members" : [ { "_id" : 0, "name" : "JenEricsMacPro.local:27017", "health" : 1, "state" : 1, "stateStr" : "PRIMARY",

问题 I'm developing a PHP application in which we need to retrieve results within a certain boundary, but ordered by the create date of the results, not the distance. I figured MongoDB's geoNear command would be great for this, since it takes care of calculating the distance for each result. However, I was wondering if there was a way to specify sorting by the create_date attribute, rather than distance. Ideally I would create a compound key index of coordinates and create date, and then quickly

问题 I might be a bit in over my head on this as I'm still learning the ins and outs of MongoDB, but here goes. Right now I'm working on a tool to search/filter through a dataset, sort it by an arbitrary datapoint (eg. popularity) and then group it by an id. The only way I see I can do this is through Mongo's MapReduce functionality. I can't use .group() because I'm working with more than 10,000 keys and I also need to be able to sort the dataset. My MapReduce code is working just fine, except for

问题 After many comes and goes I managed to install the MongoDB Driver for PHP 5.6 and made it work on OSX El Capitan.

Between theese packages I required mongodb/mongodb which is the recomended mongo php library to use by the php Manual on line and in the driver github page. The problem I found is that Eclipse is resolving the
