<?php header('content-type:application/json;charset=utf8'); $arr = array( 'status' => true, 'errMsg' => '', 'member' =>array( array( 'name' => '李', 'gender' => '男' ), array( 'name' => '赵', 'gender' => '女' ) ) ); echo json_encode($arr); ?>

输出:
{"status":true,"errMsg":"","member":[{"name":"\u674e","gender":"\u7537"},{"name":"\u8d75","gender":"\u5973"}]}

输出:
