当我尝试向数据库提交发布请求时遇到问题。有趣的是，该错误仅在我使用 PHP 7.4.2 版本时发生。在 PHP 7.3.9 版本中一切正常。我正在使用 Laravel 6.17。

Laravel 什么时候解决这个问题？

这是我的堆栈跟踪，当错误出现时。

Laravel 存储库中已经列出了类似的问题

根据PHP-Doc，这是一个向后不兼容的变化PHP 7.4

非数组的数组式访问

bool, int, floator resourceas an array(例如$null["key"]) 现在将生成通知。

composer update为我的案例工作：

我有一个Laravel 5.6应用程序，带有Php 7.1.

此外，我必须更改laracasts/generators为fromcomposer.json才能开始，例如：^1.0dev-mastercomposer update

"laracasts/generators": "^1.0"

开始在一些旧项目上解决此问题，问题发生php artisan migrate在composer install.

这是关于PHP版本的。在 php 7.4rc 中，通过键访问数组，有时会导致错误。这个错误很少发生在 php 7.2 上。检查数组是否有成员只需使用empty($array)函数

您可能正在尝试访问非数组类型（可能是对象类型）。

我也遇到过同样的情况，但它的不同之处在于一个片段访问一个对象，而另一个片段访问一个有效的数组类型。

下面的代码产生错误Trying to access array offset of value of type int

$mymodel = MyModel::where(array(
            'someid' => $somevar
        ))->get();
foreach($mymodel as $data){
     //etc
}

我尝试将其更新为：

$mymodel = MyModel::where(array(
            'someid' => $somevar
        ))->get()->toArray();
foreach($mymodel as $data){
     //etc
}

但是，您发布代码会非常有帮助，以便我们进一步检查。

如果您使用 php 7.4 并且使用过的软件包已开发为 php <7.4，则会显示此错误。

将您的 php 版本更改为旧版本（例如，php 7.4 到 7.3）。

我使用了 php 7.4 FPM，但 mPDF 的固定版本适用于 php 7.3 及以下版本。在我将 php 版本更改为 7.3 并且它工作后，我发现了这个错误。

我也用过宅基地。查看我的 php 配置：

sites:
    - map: myapp.test
      to: /home/vagrant/code/myapp/public
      php: "7.3"

vagrant reload --provision在 CLI 中运行。此命令应用新配置。
