【问题描述】：

在我的控制器中，当我执行 $request->all() 以从表单中获取所有输入时，它不会输出所有输入。即使它应该有 146 个 key->value 对，它总是限制为 56 个。

```
  array:56 [▼
  "_token" => "ZgjRs0eg0WN9fgqylFd348kUcJErej0VBaSEcDf1"
  "current_user" => "default@default.com"
  "Devices" => ""

    ]
```

而且它只发生在我的 ubuntu 服务器上。我的本地主机工作正常。是什么导致了这个问题？

【问题讨论】：

是的，但限制并不特定于 laravel。检查 Max input vars 和 Max post size 的设置。
你使用 var_dump 吗？因为 var_dump 限制了输出。您可以使用 file_put_contents 将输出写入文件以查看实际结果。
max_input_vars = 100000 和 post_max_size = 8M。我正在使用 dd() 来输出它
@bishop 我需要改变什么？
PHP 设置一切正常。我会首先检查您浏览器的网络选项卡以查看原始请求是什么：确保它实际上发送了您认为的所有数据。

标签： php laravel apache

【解决方案1】：

修复它。我正在编辑/etc/php/7.1/cli/php.ini 而不是/etc/php/7.1/apache2/php.ini。现在更改max_input_vars = 20000 后，它可以工作了。
