    <p>I'm using PHP and MongoDB to sore and to get the nearest points to my position. But I have a problem.</p> <p>When I use the mongo console, it returns values but when I'm doing by PHP code, it returns a null object.</p> <p>PHP Code:</p> <pre><code>$connection = new MongoClient( "mongodb://localhost" ); $db = $connection-&gt;collection; $collection = $db-&gt;user_location; // There are many differnt queries (by token, by email...) if (isset($_GET['email'])) { $query = array( //'email' =&gt; array( '$neq' =&gt; $_GET['email']), 'loc' =&gt; array( '$near' =&gt; array( 'lon' =&gt; floatval($_GET['longitude']), 'lat' =&gt; floatval($_GET['latitude']), '$maxDistance' =&gt; intval($_GET['distance'])))); } $maxDistance = $_GET["distance"]; $lon = $_GET['longitude']; $lat = $_GET['latitude']; $cursor = $collection-&gt;find($query); if ($cursor) { echo json_encode($cursor); } else { echo "{ 'status' : 'false' }"; } </code></pre> <p>This is an example of mongo console use: db.user_location.ensureIndex({ loc : "2d"} )</p> <blockquote> <p>db.user_location.find() { "_id" : ObjectId("51dbe817617c6df061000000"), "email" : "zgz", "loc" : { "lon" : -0.88588498, "lat" : 41.68035677 }, "date" : "Tue, 09 Jul 2013 06:38:15" } db.user_location.find({"loc": {"$near": {"lon":-0.88588498,"lat":41.68035677}, "$maxDistance":99}}) { "_id" : ObjectId("51dbe817617c6df061000000"), "email" : "zgz", "loc" : { "lon" : -0.88588498, "lat" : 41.68035677 }, "date" : "Tue, 09 Jul 2013 06:38:15" }</p> </blockquote> <p>If I use the same values in my PHP code, it returns a null cursor. Why? Thanks!</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
