试图创建一个Facebook应用程序只是为了学习，遇到了一个奇怪的现象，我不知道该怎么做。
我了解所有的 JSON 转换，但似乎我一次无法查询超过 2 个 facebook 值，而据说我应该能够......（如果这是混淆，???抱歉）。下面是我断章取义的代码。
$query="query".$i;
$idarray["$query"]="SELECT+pic,name+FROM+user+WHERE+uid=".$friend_id[$i];
当我尝试查询的不仅仅是图片和名称时，它只给了我两个。它不会让我查询诸如"图片，名称，用户名"等内容。有谁知道原因吗？如果是这样，我该如何解决这个问题以查询超过 2 个？
提前谢谢你！
这对我来说很好用，我无法确定你在做什么导致它不起作用：
select uid, name, first_name, middle_name, last_name, sex, locale, pic_small_with_logo, pic_big_with_logo, pic_square_with_logo, pic_with_logo, username from user where uid in (4,5,6,7)
返回为：
