Convert PHP mongodb findOne result to old associative array? - php

Question

I'm having issues with the new mongodb driver for php.
While iterator_to_array works ok for ->find, if I only return one document it has MongoDB\Model\BSONDocument format.
$result = $db->clients->findOne(array('_id' => $id));
$result = (array) $result;
In Mongo the document looks something like:
{
"_id" : ObjectId("3894713i4b13iu412"),
"active" : true,
"logo" : "this is logo",
"settings" : {
"email" : "days",
"testMode" : false
},
"stats" : {
"f" : {
"all" : [
{
"count" : NumberLong(15846),
"sum" : NumberLong(149479)
},
{
"count" : NumberLong(15846),
"sum" : NumberLong(148891)
},
{
"count" : NumberLong(15846),
"sum" : {
"1" : NumberLong(15522),
"2" : NumberLong(324)
}
}
]
},
"l" : {
"order" : ISODate("2016-12-05T09:10:53.855+0000"),
"feedback" : ISODate("2016-12-05T08:34:48.403+0000")
}
},
"title" : "hhh.ro",
"url" : "sdfasdf"
}
This will only turn first level elements into an array, but nested document elements still remain MongoDB\Model\BSONDocument;
iterator_to_array doesn't work because this is not something iterable.
How do I convert entire document to an associative array like the old mongo driver or a stdClass?

Answer 1

you can set how the data is returned globally in database->setCollection options, Set typeMap to array
'typeMap' =>[
'document' => 'array',
'root' => 'array'
]

Answer 2

I couldn't find the setCollection suggested by #Delcon in PHP MongoDB library so I used the below method.
typeMap option can also be set in the options array inside findOne.
$someCollection->findOne(
[],
['typeMap' => ['root' => 'array', 'document' => 'array', 'array' => 'array']]
);

edit:
You could also pass the options array to the connector to set it globally as described by this Stackoverflow post.
$options = ["typeMap" => ['root' => 'array', 'document' => 'array']];
$conn = new MongoDB\Client("mongodb://localhost:27017", [], $options);
