Passing variables from function-function in class

[ChadNomad]

Hi,

 

I'm still pretty new to OOP and have just started writting my first registration class. Everything is going well except I can't seem to pass a variable from one function to another. For example if in function a() $test = "hello" it won't work if I use it in function b().

 

How do I make them "global"? I don't quite understand the what global vars actually are but apparently it's bad practice and I haven't had much luck in my tests with them. I also only want it to be "global" in the class I've created.

 

Hope that wasn't too confusing!

 

Would $this-> work? <- only just thought of that after posting.

 

Thanks

You would use the $this keyword, yes.

 

<?php

Class A{

  var $foo;

 

  function bar(){

      $this->foo = 'Hi';

  }

 

  function myFunc(){

      $this->foo = 'Hello';

  }

 

?>

She's too quick for me.

 

<?php
class a
{
      private $test;

      function a() {
             $this->test = "hello";
      }

      function b() {
              echo $this->test;
      }

}

?>

You can also (if you have 2 classes) have the class you want to grab the variables, and inherit the first class.

Thanks. Function to function is fine now. Still... I'm now trying to use a variable outside of both the function and class.

 

echo $registration->errorString;

 

The above does nothing. I've included the class in an external file. At the bottom of the class file I have:

 

$registration = new Registration();

 

Am I doing something wrong??
