    public $timestamps = false;

    /*public function profile()

                                                </a>
                                                 |
                                                <a href='$editUrl' data-method='delete'
                                                data-confirm='Are you sure?  User will be delete.'>
                                                <i class='icon-trash text-danger'></i>
                                                </a>";
            } else {
                $data['data'][$sl]['action'] = "<a href='$editUrl' data-method='delete'
                                                    data-confirm='Are you sure? Do you want to restore this User?'>
                                                <i class='icon-reload text-danger'></i>
                                                </a>";
            }

            $sl++;
        }

        echo json_encode($data);
        die();
    }

这是经理模型

class AclManager extends Model
{

    protected $table = 'reign_acl_managers';
    public $timestamps = false;

    public function parent()
    {
        return $this->hasOne('App\Model\AclManager', 'id', 'parent_id');
    }

    public function manager()
    {
        return $this->hasOne('App\Model\AclGroup', 'id', 'group_id');
    }

}

我有两张表，一张是超级管理员，另一张是经理，我正在尝试获取订阅用户和他们所属的经理，有些用户属于超级管理员，但在manager 表，所以它们在表中的所有者将为 0， 所以当我试图获取所有者详细信息时，我得到了

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旧版本的 laravel 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。

【问题讨论】：

  • 您是否停下来阅读 PHP 和 Laravel 的升级说明。您跳过了这两个版本的几个版本，因此您希望在进行跳转之前至少必须检查升级说明
  • 您尝试过什么调试问题？如果那是您自己的代码行抛出这样的错误或警告，为什么不修复您的代码？
  • 我想修复代码，但我不知道该怎么做，因为我说这种关系与旧版本很好，所以我不知道问题出在哪里跨度>
  • 这是错误 [2021-02-13 15:40:25] local.ERROR: Trying to access array offset on value of type null {"exception":"[object] (ErrorException(代码：0）：尝试在 /var/www/html/easy/app/Http/Controllers/CrmController.php:281 处访问 null 类型值的数组偏移量）[stacktrace]
  • 我应该改变关系吗？经理必须属于父母或者他们必须是他们自己的父母，当我试图获取属于超级管理员的订阅者时，我收到此错误，因为他们的所有者ID将为0，并且在经理表中找不到此ID

【解决方案1】：

问题是$val-&gt;owners 是null。

在旧版本的 PHP 中，每当您尝试对 null 变量使用 [] 运算符时，都会通过返回 null 静默处理此错误/通知。

您可以通过先使用 PHP 7.3 然后使用 PHP 7.4 运行以下代码来测试：

<?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，出现这些错误是很正常的，因为过去使用的语言有点过于宽松。

LE：条件$val-&gt;owners['full_name'] == "" 之前已经有效，因为null == "" 的计算结果为true，您可以将其替换为!isset($val-&gt;owners['full_name'])
