aggregate_info - Gets aggregation information for a given object

SYNOPSIS

       array aggregate_info (object  $object)

DESCRIPTION

	Gets the aggregation information for the given $object.

PARAMETERS

	      o $object
		-

RETURN VALUES

	Returns the aggregation information as an associative array of arrays of methods and properties. The key for the main array is the name of
       the aggregated class.

EXAMPLES

       Example #1

	      Using aggregate_info(3)

	      <?php

	      class Slicer {
		  var $vegetable;

		  function Slicer($vegetable)
		  {
		      $this->vegetable = $vegetable;
		  }

		  function slice_it($num_cuts)
		  {
		      echo "Doing some simple slicing
";
		      for ($i=0; $i < $num_cuts; $i++) {
			  // do some slicing
		      }
		  }
	      }

	      class Dicer {
		  var $vegetable;
		  var $rotation_angle = 90;   // degrees

		  function Dicer($vegetable)
		  {
		      $this->vegetable = $vegetable;
		  }

		  function dice_it($num_cuts)
		  {
		      echo "Cutting in one direction
";
		      for ($i=0; $i < $num_cuts; $i++) {
			  // do some cutting
		      }
		      $this->rotate($this->rotation_angle);
		      echo "Cutting in a second direction
";
		      for ($i=0; $i < $num_cuts; $i++) {
			  // do some more cutting
		      }
		  }

		  function rotate($deg)
		  {
		      echo "Now rotating {$this->vegetable} {$deg} degrees
";
		  }

		  function _secret_super_dicing($num_cuts)
		  {
		      // so secret we cannot show you ;-)
		  }
	      }

	      $obj = new Slicer('onion');
	      aggregate($obj, 'Dicer');
	      print_r(aggregate_info($obj));
	      ?>

	      The above example will output:

	      Array
	      (
		  [dicer] => Array
		      (
			  [methods] => Array
			      (
				  [0] => dice_it
				  [1] => rotate
			      )

			  [properties] => Array
			      (
				  [0] => rotation_angle
			      )

		      )

	      )
	As you can see, all properties and methods of the Dicer class have been aggregated into our new object, with the exception  of	the  class
       constructor and the method _secret_super_dicing

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)
	      {

	      }

	      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
