A great thing about Python is that it can pass parameters to a function by name. it looks like this: 1my_foo_function (param_name = & quot; value & quot;, another_param_name = & quot; anothervalue & quot;) today I want to do the same thing in PHP5.4

When you re-specify a parameter with the default value, you can explicitly assign a value to the name of the specified parameter. When it is implicitly specified, it is inferred by the c # compiler based on the sequence of method parameters.

When you reassign a parameter that assigns a default value, you can explicitly assign a value to the specified parameter name, which is inferred by the C # compiler based on the order of the method parameters, as implicitly specified. code example:

  1. params ParamsYou can specify the parameter's method parameter when the number of parameters is variable. In the method declaration, only oneParamsKeyword, which is the last parameter. Using System; Class App{Public static void UseParams (params

Optional parameters are supported in C #4.0. Assign a constant to a parameter when declaring a method. You do not need to specify each parameter when calling this method.   Code highlighting produced by Actipro CodeHighlighter

Reflection characteristics (Attribute)Many people may not yet understand the features, so let's look at what is a feature first. Think about it. If there is a message system, it has a way to send a short message to someone:Title: Author: Author;

Advantages of using binding parameters:Why do we use binding named parameters? The existence of any one thing has its value, specific to the binding parameters for HQL query, there are the following two main advantages:①, performance optimizations
