PHP Accessing one array from class – Twitter-api

I’m trying to access a single value of an array, I can’t seem to get it right. This is the code:

    $socialCounts = new socialNetworkShareCount(array(
    'url' => 'http://facebook.com/',
    'facebook' => true,
    'buffer' => true,
    'pinterest' => true,
    'linkedin' => true,
    'google' => true
));

 print_r($socialCounts->getShareCounts());

Which Returns the following:

{"facebookshares":52132062,"facebooklikes":0,"pinterestshares":243942,"linkedinshares":4708,"googleplusones":0,"buffershares":207477,"total":52588189}

How can I access the vaule of each individual Item? For example, if I’d like to echo the facebook shares value.

And this is the full class if you need:

class socialNetworkShareCount{

    public $shareUrl;
    public $socialCounts = array();
    public $facebookShareCount = 0;
    public $facebookLikeCount = 0;
    public $twitterShareCount = 0;
    public $bufferShareCount = 0;
    public $pinterestShareCount = 0;
    public $linkedInShareCount = 0;
    public $googlePlusOnesCount = 0;


    public function __construct($options){

        if(is_array($options)){
            if(array_key_exists('url', $options) && $options['url'] != ''){
                $this->shareUrl = $options['url'];
            }else{
                die('URL must be set in constructor parameter array!');
            }

            // Get Facebook Shares and Likes
            if(array_key_exists('facebook', $options)){
                $this->getFacebookShares();
                $this->getFacebookLikes();
            }

            // Get Twitter Shares
            if(array_key_exists('twitter', $options)){
                $this->getTwitterShares();
            }

            // Get Twitter Shares
            if(array_key_exists('pinterest', $options)){
                $this->getPinterestShares();
            }

            // Get Twitter Shares
            if(array_key_exists('linkedin', $options)){
                $this->getLinkedInShares();
            }

            // Get Twitter Shares
            if(array_key_exists('google', $options)){
                $this->getGooglePlusOnes();
            }

            $this->getLinkedInShares();

    According to the class definition, you don’t need to invoke getShareCounts(). It looks like that method is perhaps used to provide some lower end API functionality. I don’t think it’s meant for your use case.

    All of the below public variables are accessible and filled in once the constructor has run.

    public $facebookShareCount = 0;
public $facebookLikeCount = 0;
public $twitterShareCount = 0;
public $bufferShareCount = 0;
public $pinterestShareCount = 0;
public $linkedInShareCount = 0;
public $googlePlusOnesCount = 0;

    So you can access them like so:

    $socialCounts = new socialNetworkShareCount(array(
    'url' => 'http://facebook.com/',
    'facebook' => true,
    'buffer' => true,
    'pinterest' => true,
    'linkedin' => true,
    'google' => true
));

print_r($socialCounts->facebookShareCount); // facebook shares
print_r($socialCounts->facebookLikeCount); // facebook likes

    mixed json_decode ( string $json [, bool $assoc = false [, int $depth
    = 512 [, int $options = 0 ]]] )

    Source.

    Since your json is an object, json_decode($yourparam) will return an stdClass by default, which will have public members. Since you would like to use an associated array instead, you need to call something like json_decode($yourparam, true), which will return an associated array, since the second parameter is a boolean value determined by your intention whether you want an associated array as result, default value being false.
