EXAMPLES
       Example #1

	      get_class_vars(3) example

	      <?php

	      class myclass {

		  var $var1; // this has no default value...
		  var $var2 = "xyz";
		  var $var3 = 100;
		  private $var4;

		  // constructor
		  function myclass() {
		      // change some properties
		      $this->var1 = "foo";
		      $this->var2 = "bar";
		      return true;
		  }

	      }

	      $my_class = new myclass();

	      $class_vars = get_class_vars(get_class($my_class));

	      foreach ($class_vars as $name => $value) {
		  echo "$name : $value
";
	      }

	      ?>

	      The above example will output:

	      var1 :
	      var2 : xyz
	      var3 : 100

       Example #2

	      get_class_vars(3) and scoping behaviour

	      <?php
	      function format($array)
	      {
		  return implode('|', array_keys($array)) . "
";
	      }

	      class TestCase
	      {
		  public $a    = 1;
		  protected $b = 2;
		  private $c   = 3;

		  public static function expose()
		  {
		      echo format(get_class_vars(__CLASS__));
		  }
	      }

	      TestCase::expose();
	      echo format(get_class_vars('TestCase'));
	      ?>

	      The above example will output:

	      // 5.0.0
	      a| * b| TestCase c
	      a| * b| TestCase c

	      // 5.0.1 - 5.0.2
	      a|b|c
	      a|b|c

	      // 5.0.3 +
	      a|b|c
	      a
