EXAMPLES

       Example #1

	      Using get_class(3)

	      <?php

	      class foo {
		  function name()
		  {
		      echo "My name is " , get_class($this) , "
";
		  }
	      }

	      // create an object
	      $bar = new foo();

	      // external call
	      echo "Its name is " , get_class($bar) , "
";

	      // internal call
	      $bar->name();

	      ?>

	      The above example will output:

	      Its name is foo
	      My name is foo

       Example #2

	      Using get_class(3) in superclass

	      <?php

	      abstract class bar {
		  public function __construct()
		  {
		      var_dump(get_class($this));
		      var_dump(get_class());
		  }
	      }

	      class foo extends bar {
	      }

	      new foo;

	      ?>

	      The above example will output:

	      string(3) "foo"
	      string(3) "bar"
