Sending variables between 2 functions

That is some bad example code

If you have methods (functions) in a class you can do

Code:

class Someclass
{
   var $foo;

   function a()
   {
      $this->foo = 1
      $this->b();
   }

   function b()
   {
      if(is_numeric($this->foo))
      {
          return $this->foo + 1;
      }
      else
      {
          return 10;
      }
   }
}

if it are separate functions you can only pass values by using parameters. You could use a global but that is bad practice.
