在 Laravel 6 中,任务队列一直运行中的排查分析(由于函数重复定义,PHP 会 发出致命错误(fatal error))

1、参考:在 Linux 、Laravel 6 中,任务队列一直运行中的排查分析(已经设置超时时间):https://www.shuijingwanwq.com/2022/11/10/7139/ 。之前的原因是由于在执行 Artisan::call 时,命令行未返回 1 进而导致判断失效。

2、但是在解决之后,再一次出现了任务队列一直运行中的情况。报错:PHP Fatal error: Cannot redeclare settingUrl() (previously declared in E:\wwwroot\object\Modules\ThemeStoreDB\Resources\setting_migrations\v2.0.23\migrate_settings_data.php:31) in E:\wwwroot\object\Modules\ThemeStoreDB\Resources\setting_migrations\v2.0.23\migrate_cart.php on line 40。如图1

3、PHP Fatal error 的原因在于:在 include 所包含的文件中,由于函数重复定义,PHP 会 发出致命错误(fatal error)。

4、最终决定临时的解决方案是将所包含的文件中,重名的函数给修改为不一样的名称,以规避掉此问题。
