升级 laravel 和 php 版本后出现问题
problem after upgrading laravel and php version
我在 laravel 5.2.45 和 PHP 7.1 上工作没有任何问题，然后我决定升级到 laravel 7 和 php 7.4
我从事的项目正在运行，但我在某些页面上遇到问题，尤其是 laravel 中的属于关系，我收到此错误

我有2个tables，一个是给超级管理员的，另一个是给经理的，我想得到订阅的用户和他们所属的经理，一些用户属于在经理 table 中找不到超级管理员，因此 table 中他们的所有者将为 0，
所以当我试图获取所有者详细信息时，我得到
Trying to access array offset on the value of type null
在这一行
$data['data'][$sl]['owner'] = $val->owners['full_name'] == "" ? "Admin" : $val->owners['full_name'];
问题是相同的代码在 laravel 的旧版本上运行良好，但在这个新版本中却不行。我认为问题出在模型中的关系上，但我不知道如何解决。
问题是 $val->owners 是 null。
在 PHP 的旧版本中，每当您尝试在 [=12= 上使用 [] 运算符时，此 error/notice 都会通过返回 null ]变量。
您可以通过 运行 下面的代码先使用 PHP 7.3 然后 PHP 7.4 来测试它：
<?php
$a = null;
var_dump($a['a']);
PHP 7.3 将打印 NULL，而 PHP 7.4 将抛出您提到的错误。
在升级您的 PHP 版本时，出现这些错误是正常的，因为过去该语言过于宽松。
LE：条件 $val->owners['full_name'] == "" 之前有效，因为 null == "" 的计算结果为 true，您可以将其替换为 !isset($val->owners['full_name'])

我有2个tables，一个是给超级管理员的，另一个是给经理的，我想得到订阅的用户和他们所属的经理，一些用户属于在经理 table 中找不到超级管理员，因此 table 中他们的所有者将为 0， 所以当我试图获取所有者详细信息时，我得到
Trying to access array offset on the value of type null
在这一行
$data['data'][$sl]['owner'] = $val->owners['full_name'] == "" ? "Admin" : $val->owners['full_name'];
问题是相同的代码在 laravel 的旧版本上运行良好，但在这个新版本中却不行。我认为问题出在模型中的关系上，但我不知道如何解决。
问题是 $val->owners 是 null。
在 PHP 的旧版本中，每当您尝试在 [=12= 上使用 [] 运算符时，此 error/notice 都会通过返回 null ]变量。
您可以通过 运行 下面的代码先使用 PHP 7.3 然后 PHP 7.4 来测试它：
<?php
$a = null;
var_dump($a['a']);
PHP 7.3 将打印 NULL，而 PHP 7.4 将抛出您提到的错误。
在升级您的 PHP 版本时，出现这些错误是正常的，因为过去该语言过于宽松。
LE：条件 $val->owners['full_name'] == "" 之前有效，因为 null == "" 的计算结果为 true，您可以将其替换为 !isset($val->owners['full_name'])
