これをどのように使用すれば、配列からツイートを選択できるようになりますか。$tweets[2];json_decode を試しましたが、うまくいきません。

JSON 出力を文字列に保存しようとすると、単一引用符がエスケープされていないために失敗します。

たとえば、JSON 出力に次のテキストがあります。

"text": "\"I fear we'll get ourselves involved in another endless conflict\" 
            //------^

そのため、JSON を文字列に割り当てようとすると、単一引用符が含まれているために失敗し、解析エラーが発生します。JSON には二重引用符が含まれているため、それも使用できません。

引用符を無視して文字列として解釈するように PHP に指示するには、次のようにヒアドキュメント構文を使用できます。

$string = <<<JSON
... json ...
JSON;

$json = json_decode($string);
echo $json[0]->text."\n"; 
echo $json[1]->text."\n";

json_decode()注: 代わりに連想配列を取得する場合は、 asの 2 番目のパラメーターを渡すことができますTRUE。

動作デモ！
