来自数组的回声数据[关闭]

Question

I am currently calling Twitter's "Trending" API with PHP and I want to return the top 10 trending topics. Currently it appears to be echoed into an array but I can't work out how to get an individual piece of data on it's one.

I want to just return the name attribute for each one. How can I do this?

My existing code is:

<?

$search=file_get_contents("https://api.twitter.com/1/trends/1.json");
print_r(json_decode($search));

?>

Decoded array:

Array
(
    [0] => stdClass Object
        (
            [trends] => Array
                (
                    [0] => stdClass Object
                        (
                            [name] => #EuroclubSoloEnEuropaFM
                            [url] => http://twitter.com/search?q=%23EuroclubSoloEnEuropaFM
                            [promoted_content] => 
                            [query] => %23EuroclubSoloEnEuropaFM
                            [events] => 
                        )

                    [1] => stdClass Object
                        (
                            [name] => #NBABands
                            [url] => http://twitter.com/search?q=%23NBABands
                            [promoted_content] => 
                            [query] => %23NBABands
                            [events] => 
                        )
                       //...

I would assume that json_decode returns an associative array. You could get the value of the name by doing this:

<?

$search=file_get_contents("https://api.twitter.com/1/trends/1.json");
$trends = json_decode($search);
foreach ($trends[0]->trends as $trend){
    echo $trend->name . "<br/>";
}
?>
