When PHP calls method A of the parent class in subclass Method B, the name of Method B can still be obtained without passing parameters.

In PHP

 
ClassA {

FunctionName (){}

}

ClassBExtendsA {

FunctionChildname (){$ This-> Name ();}

}
 

 

When subclass B calls childname (), how does one obtain the method name childname in the name method of parent class A without passing parameters?

 

 Class A {
 Function _ Call ( $ N , $ ){ If ( $ N = '_ Call _'){ $ N = $ [0]; $ This -> ___ Name = $ N ; $ This -> $ N ();}}
 Function Name (){
 Echo   $ This -> ___ Name; //  /Childname  
 }
}

Class B Extends A {
 Function Childname (){
 $ This -> Name ();
}
}

 
Use an index. php as the entry file
 

 
<? PHP
Require("B. Class. php ")
B-> _ call _($ _ Get['A']);
 

   of course, replace B with $ _ Get ['M'], which is the default entry of a framework.
