Use array helper functions to implement unlimited order filling parameters

In general, we often need to pass arguments to a function when we define a function in a class

1<?PHP2 3     classimage{4 5          Private $name;6          Private $age;7          Private $adress;8 9          functionGetInfo$name,$age,$adress){Ten  One                 $this->name =$name; A                 $this->age =$age; -                 $this->adress =$adress; -          } the  -}

In the process of using the function, we need to enter the parameters strictly in accordance with their order, and can not miss a parameter,

Although the parameter is set to a default value, it is still given a position.

In the learning of Gaulo Teacher's detail in PHP, Gao spoke about the use of arrays to implement the free-form parameter input,

The following steps are implemented:

First, when you define a function, put all the parameters in the array:

 Public function getinfo ($options = Array () ) {}

Then you need to assign the parameters in the array to the property values of the class in the function's contents.

When calling a method:

$arr Array (' name ' = ' Timor ', ' age ' =>12, ' adress ' = ' yudel ') {            }

When defining a function, assign the parameters that the function receives to the properties of the class:

That is, the argument used by the function must be a property in the class or a variable defined in the script

In the class:

1      Public functionGetInfo$options=Array() ){2 3             foreach($options  as $key=$val{//Remove parameters from the array4                 if(!In_array($key,Get_class_vars(Get_class($this))) {//Determine if the parameters and properties in the class are the same5                     Continue;6}Else{7                     $this->$Key=$val; Assigning the value of a parameter to a property in a class8                 }9             }Ten}

After that, when we need to call GetInfo (), we can write the following form:

1GetInfo$arr=Array(' name ' = ' Timor ', ' age ' = 12)){2 3 }4 5 //You can also disrupt the order of the parameters6 7GetInfo$arr=Array(' age ' = +, ' name ' = ' Timor ') )){8 9 }Ten  One //You can also miss a parameter and not write it . A  -GetInfo$arr=Array(' name ' = ' Timor ' )){ -  the}

I don't know if this is a bit of a detour ...

It seems to me that this is a good way to implement flexible calling functions, but I don't seem to be optimistic about this approach.

It calls a lot of methods, which will take up some extra memory, and as if doing so will give people a sense of confusion,

Enclosing the parameters in the array seems to complicate the definition of the parameters ...

See practicality later ...
