Just a note: aggregate_methods doesn't aggregate those methods already defined in the class, including those methods inherited from a parent class.

Here's an example:

- If class B inherits from class A and aggregates methods from class C:

<?php

class A {
          function foo() {
                echo 'from class A';
          }
}

class B extends A {
    function B() {
         aggregate_methods($this,'C');
    }
}

class C {
          function foo() {
                echo 'from class C';
          }
}

$myclass = new B();
$myclass->foo();
// This will print 'from class A'

?>

You can use this to dynamicily add methods to a class

class foo {
  function addMethod(  $code ) {
    $cname = uniqid("class");
    eval( "class ${cname} { ${code} }" );       
    aggregate_methods( $this , $cname );
  }

  function bar() {
    $this->addMethod( "function baz() { echo 'sha'; }" );
  }
}

$bang = new foo();
$bang->bar();
$bang->baz();
