我这里有一个Json字符串。 https://graph.facebook.com/402341223174008_403132789761518?access_token=AAACEdEose0cBAKvST4yvRNg0ViRuvwLdKlCSk13x2NWAobGfq0QOASS3yBdsm1e4aZA57ZAfCjSCD0ta2HWjo3ZClgoYlR6CFFdu4q7180h8D1P7A87。现在这包含来自facebook组的帖子的评论。我想得到所有评论过这篇文章的人的名字。
我希望所有的名字和名字都不应该重复（因为许多人不止一次评论过）。
我们可以通过
获得名字$a = file_get_contents ('https://graph.facebook.com/402341223174008_403132789761518?access_token=AAACEdEose0cBAKvST4yvRNg0ViRuvwLdKlCSk13x2NWAobGfq0QOASS3yBdsm1e4aZA57ZAfCjSCD0ta2HWjo3ZClgoYlR6CFFdu4q7180h8D1P7A87');
$json_decoded = json_decode($a);
echo $json_decoded->comments->data[1]->from->name;
以下是完整的JSON字符串。请帮帮我。
