我正在尝试将我的JSON数据转换为数组＆amp;然后显示来自tje JSON数据的记录计数。
我已经解码了JSON数据，但我无法计算记录。数据：

您可以使用count函数获取任何数组的计数。
您可以使用它的数组键访问任何子数组。
$records = $array['http://apps.facebook.com/moviecornpopcorn/index.php/ratemovie/comments?movieid=513']['data'];
$count = count($records);
答案 1 :(得分：0)
你有非常讨厌的数组键:)所以获取当前元素（使用url作为数组键）值并计算它的值
<?php $data = current($yourarray); $dataCount = count($data); ?>
