Hello

First of all i am very weak about OOP and classes in php. I am learning now but i stuck with very silly problem.

My codes are below.

<?php
   class myTestClass
   {
       function __construct()
       {
         $this->OldName("This is Old Name");
       }
       
       function OldName($VeryOld)
       {
           if($VeryOld == "This is Old Name")
               $this->NewName();
            else
               $VeryOld = "Something Wrong";
            return $VeryOld;
       }
       
       function NewName()
       {
           echo "This is Brand New Name";
       }
   }
   
   $i = new myTestClass();
?>

 

if i send value to  OldName "This is Old Name" then codes works fine.

But if i send "This is Old Nameeee" then does not appear anything.

 

what i want to do is print "Something Wrong" text if i enter different value. I have no idea what return do and how it do? How to retrieve/print "Something Wrong"?

i can do that with echo but i want to transfer result of return to another function.

 

Really appreciate for any help/idea.

Firstly, your logic itself doesn't really make sense. It says, (calling OldName()) if the username provided is the same as the current name, call a function that displays 'this is a brand new name'

 

Can you see any sense it that logic?

First of all, i am very very very beginner of class.

All i want to do is autorun class when it created. Then Skip to OldName and parse same variable.

Check that variable, if it is true then go to NewName else return error message.

 

Like i said i am new about OOP. I can do what i want with functions but i want to learn class.

The logic you have described has nothing to do with whether or not its done inside a class or not, besides, this really is a bad example of how classes work.

 

Generally, a class wouldn't automtically execute its functionality when instantiated.
