Question

这是我的方案，例如我在数据库中有4000个联系人（在json_encode之后返回271257行），我已经调用了

echo json_encode($response);

但作为JSON返回响应需要35-40秒。所以我的问题是，是否还有其他选项可以将转换过程减少到json。所以我可以快速申请我通过调用以下函数

尝试了很多

1) json_encode($response, JSON_UNESCAPED_UNICODE);

2) 
header('Content-Type: application/json')
echo json_encode($response);

3)
header('Content-Type: application/json')
echo json_encode($response); die;

这是单一联系人的样本数据

                "primary": {
                    "id": "",

它不是json_encode错误。如果你运行下面的代码，你可以看到它会在不到3秒的时间内完成。因为你向用户显示的输出大小和渲染时间。你可以分页你的输出而不是一起展示所有这些

<?php
$str = [];
for($i = 0;$i<4000;$i++){
    $str[] = "sample data";
}
$json = json_encode($str);

echo strlen($json);

Json_encode需要花费很多时间来转换为JSON作为响应
