[SOLVED] Using function variables outside a class?

[ChadNomad]

How do you use a variable outside a class? I've included a class on a page and I want to echo a string made within a function.

 

Thanks.

If by this you mean you've declared a variable that you want to use inside of a class you do the following.

 

$var = "sample";

class testClass {
public function grabGlobalVar(){
   global $var;
   echo $var; // will result in "sample"
}
}

Heres the setup. Maybe this will make more sense. I'm trying to use a variable from a function inside a class and use that in a completely different page where the class file is included.

 

login.class.php

class Login()
{
   function ProcessLogin($username, $password)
   {
       $this->MyVar = "Hello";
   }
}

$login = new Login();
$login->ProcessLogin($username, $password)

 

login.php

include("login.class.php");

echo $login->MyVar; // <- This is my problem. Doesn;t work... 

 

I've tried using "global" to no avail...

Use:

class Login()
{
var MyVar;
   function ProcessLogin($username, $password)
   {
       $this->MyVar = "Hello";
   }
}

$login = new Login();
$login->ProcessLogin($username, $password)

Then try:

 

include("login.class.php");

echo $login->MyVar;

try instantiating the Login() class on login.php

 

what version of php are you running? maybe you should declare your class properties first

 

class Login(){

var $MyVar; //php4

public $MyVar;//php5

 

...

}
