Question

I’m getting a json result back from an api request to the freebase database.
This is part of the object returned called $json. A var dump of $json:

stdClass Object
(
[name] => Abomey
[/location/statistical_region/population_growth_rate] => 
[/common/topic/article] => Array
    (
        [0] => stdClass Object
            (
                [id] => /m/0jk2c
            )
    )

How can I subtract the /m/0jk2c part?

$json->/common/topic/article[0]->id (obviously) doesn’t work.

Answer 1

This should do it:

$json->{"/common/topic/article"}[0]->id
