In Laravel, performance comparison of request['name'] and request->get('name')

Question

In Laravel, what is the relationship between request['name'] and request->get('name')?

Answer 1

It doesn’t matter...if anything, they have one thing in common: they can all take parameter values.
Difference:

• get() 是 Symfony Request 实现的，可以获取到 $request 的 attributes, query, request 里的值，并可以指定一个默认值。本意主要是提供给第三方框架取值或重写使用的。一般情况都是取到了 query 里的值，基本等同与 isset($_REQUEST['name']) ? $_REQUEST['name'] : $default .

• The array method is the method provided by Laravel to obtain the query parameter value. It is of course a little bit different for $request->all() 进行 data_get()，支持 name 里的“点”分割获取数组的值，比如 $request['foo.bar'], 性能上比直接 get(), but it is very "Laravel way".

• get() 方法在 Laravel 中对应的方法是 input() 和 file().

• In addition to array methods, Laravel also provides many convenient methods to manipulate parameter values, such as exists has all only except intersect etc...

• In Laravel, it works for $request 直接属性访问也可以取参数值，比如 $request->name, but it is not recommended to use this method when it is unclear whether the name parameter exists
