class_exists():不赞成将null传递给字符串类型的参数#1($class)

Question

我有这个新安装的Yii2高级版，想知道你们中是否有人在从前端登录后遇到过这个错误？

你采取了什么解决方案来解决这个问题？

下面是我的composer.json

Answer 1

从php8.1开始，您就不能在class_exists函数中放入null值。要解决此问题，请在文件\vendor\yiisoft\yii2-debug \src\panels\UserPanel.php中替换第90/91行

if (!is_object($this->filterModel)
&& class_exists($this->filterModel)

带有

if (!is_object($this->filterModel) && $this->filterModel !== null
&& class_exists($this->filterModel)

这不是一个好的解决方案，因为我们正在编辑yii的源代码，但有效：(Yii的2.0.46版本可能会修复这个

Answer 2

它在634b9cc5e89bcc65091fe25ea2b5538b5bc5ce76中被修复，所以当新版本发布时，它将被修复，同时您可以使用"yiisoft/yii2-debug"："dev master#">
