Question

我有以下问题，我将symfony放在服务器上，将它在app_dev.php debug中更改为false，在app.php中为true，现在我应该在信息php bin /控制台中获取有关我拥有的信息产品的固定版本，为什么开发人员总是向我展示？当然，调试栏将不会出现，进入URL app_dev.php / _profiler下后，我会得到一个错误

Error: Can not redeclare class Symfony\Component\Debug\ErrorHandler

但是，输入example.com/_profiler后，我得到了错误：

No route found for "GET /_profiler"

关于结果的php bin /控制台，当我将dev更改为false时，prod更改为true

如果要在生产服务器或类似服务器中调试代码，我想说至少有一个黄金法则：不要修改app_dev.php或app.php。您可以像平常一样保持prod env，同时，可以在相应的环境（即'dev'，您已经有'prod'）和端口下运行webserver捆绑软件。如您所知，代码中的任何更改都是在dev中即时编译的，在prod中，您必须清除缓存（甚至赋予适当的Web服务器权限）。据我了解，您不希望与此有所不同，因此我建议将更改还原到app * .php脚本并相应地运行webserver捆绑软件。
