如何使用PHP对用户数组进行JSON编码？

Question

Im working with a JSON file that checks, if a user is typing.

Is there any reason why this would not work?

  // Array of WP_User objects. foreach ( $user_query as $user ) { $result['whotyping'] = $user_info->whotyping; $result['typingto'] = $user_info->typingto; $result['typing'] = $user_info->typing; } echo json_encode($result); 

I thought this would work, but it returns nothing by an error.

How do I solve this problem?

  // Array of WP_User objects. foreach ( $user_query as $user ) { $result['whotyping'] = $user_info->whotyping; $result['typingto'] = $user_info->typingto; $result['typing'] = $user_info->typing; echo json_encode($result); }

You should make an array of results.

  // Array of WP_User objects. $results = array(); foreach ( $user_query as $user ) { $result = array(); $result['whotyping'] = $user_info->whotyping; $result['typingto'] = $user_info->typingto; $result['typing'] = $user_info->typing; $results[] = $result; } echo json_encode($results);
