PHP Accessing one array from class - php

Question

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();
}
// Get Buffer Shares
if(array_key_exists('buffer', $options)){
$this->getBufferShares();
}
}elseif(is_string($options) && $options != ''){
$this->shareUrl = $options;
// Get all Social Network share counts if they are not set individually in the options
$this->getFacebookShares();
$this->getFacebookLikes();
$this->getTwitterShares();
$this->getPinterestShares();
$this->getLinkedInShares();
$this->getGooglePlusOnes();
$this->getBufferShares();

Answer 1

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

Answer 2

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.
