For Laravel 5 + php7, you should be using the null coalesce operator as explained in this Laravel News article, like so:
对于 Laravel 5 + php7,您应该使用 null 合并运算符,如这篇 Laravel 新闻文章中所述,如下所示:
{{ $value ?? "Fallback" }}
Before the null coalescing operator, Blade handled the same problem with the “or” operator, which allows a default value when the first value isn't set, separated by an “or”.
在空合并运算符之前,Blade 处理了与“or”运算符相同的问题,它允许在第一个值未设置时使用默认值,用“or”分隔。
