EXAMPLES
       Example #1

	      runkit_method_redefine(3) example

	      <?php
	      class Example {
		  function foo() {
		      return "foo!
";
		  }
	      }

	      // create an Example object
	      $e = new Example();

	      // output Example::foo() (before redefine)
	      echo "Before: " . $e->foo();

	      // Redefine the 'foo' method
	      runkit_method_redefine(
		  'Example',
		  'foo',
		  '',
		  'return "bar!
";',
		  RUNKIT_ACC_PUBLIC
	      );

	      // output Example::foo() (after redefine)

	      The above example will output:

	      Before: foo!
