Clasi OOP e variabili

[the prince]

Buongiorno a tutti !

Ho questo problemma che mi affligge da giorni :-)

Da una serie di classi PHP incluse con "require_once " alla fine mi ritorna un json in questo modo

$twitter = new TwitterAPIExchange($Twitter_settings);
$twitter->setGetfield($getfield)
->buildOauth($TwitterUrl, $requestMethod)
->performRequest();

come posso usare la variabile $twitter adesso ?

io vorrei fare tipo

$Data_twitter = json_decode($twitter)

foreach ($Data_twitter as $tweety){
if (!empty($tweety)) {
array_push($ArrayText, $tweety->text);
array_push($ArrayCreated, $tweety->created);
array_push($ArrayScreen_name, $tweety->user->screen_name);
array_push($Arrayprofile_image_url, $tweety->user->profile_image_url);
array_push($ArraySocialType, "Tweet");
}
}

ma non funziona .... l'una cosa che risco a fare è un bel "echo" :-((

help me please !!!!

già provato a fare var_dump($twitter) ... non vien fuori niente di buono solo


object(TwitterAPIExchange)#1 (8) { ["oauth_access_token":"TwitterAPIExchange"rivate]=> string(49) "15503213-s3rs2rA52P3qyP4khrSdNIHczWbFWMulc3z1mQ" ["oauth_access_token_secret":"TwitterAPIExchang e"rivate]=> string(40) "MVNkXnujqnu5CeKmLcJGT7SAfwc" ["consumer_key":"TwitterAPIExchange"rivate]=> string(22) "xxxxxxxx" ["consumer_secret":"TwitterAPIExchange"rivate]=> string(43) "xxxxxxxxx" ["postfields":"TwitterAPIExchange"rivate]=> NULL ["getfield":"TwitterAPIExchange"rivate]=> string(29) "?screen_name=ebarolo&count=10" ["oauth"rotected]=> array(9) { ["oauth_consumer_key"]=> string(22) "T4fcC4xz8OtmSntUlLPprw" ["oauth_nonce"]=> int(1372689706) ["oauth_signature_method"]=> string(9) "HMAC-SHA1" ["oauth_token"]=> string(49) "15503213-s38s2rA51tP3qyP4khrSHoNIHczWbFWMulc3z1mQ" ["oauth_timestamp"]=> int(1372689706) ["oauth_version"]=> string(3) "1.0" ["screen_name"]=> string(7) "xxx" ["count"]=> string(2) "10" ["oauth_signature"]=> string(28) "wHZdUpUW7H2Gdtfa/u9xceR3KNs=" } ["url"]=> string(47) "https://api.twitter.com/1.1/favorites/list.json" }

l' unico modo per far venire fuori in modo corretto il json è


echo $twitter->setGetfield($getfield) ->buildOauth($TwitterUrl, $requestMethod) ->performRequest();

ma a questo punto non riesco ad utilizzare la varibile :-))
