The variable in the Laravel template does not define a direct crash, but the variable is not defined in the thinkphp template to perform normally

Although the debug debug output inside the thinkphp is wrong, it does not affect it at all.

Laravel directly collapse, what is the best way? I don't want to define mistakes or isset.

That's probably what you want, right?

@yield('title','默认标题')

Go to the view to see if there is a try catch in Render, find the corresponding exception, and see if it can be replaced at initialization time. Isset is the straight path.
