Crap, I didn't mean to send that. This is the actual code:


<?php
error_reporting(-1);
ini_set('display_errors',true);
ini_set('display_startup_errors',true);

class TestClass {
  var $a=20;
  var $b=10;
  function TestClass($a= null, $b=null) {
    if (!is_null($a))
      {
	$this->a = $a;
      }
    if(!is_null($b))
      {
	$this->b=$b;
      }
  }

  function printAB() {
    echo $this->a." ".$this->b."\n";
  }
}

$inst1 = new TestClass(3,50);
$inst2 = new TestClass();
$inst1->printAB();
$inst2->printAB();
?>
