Answer 1

This is an instance of class xyz which contains fields : foo and foo1.

<?php
 class xyz
  {
     var $foo=10;
     protected   $foo1=array("b"=>5,"b1"=>6);
     public function getB1() { return $this->foo1["b1"];}
  }

  $a=new xyz();
  print_r($a);

// print $a->foo1["b1"]; // can't be accessible due to protection
  print $a->getB1();
?>
