Description:
------------
PHP versions:
5.3.2-1ubuntu4.2
5.2.6-1+lenny9

There isn't mentioned a difference between 5.2 and 5.3 in interface behavior. 

In 5.2, if defined class/method has default values, interface MUST have default values.
In 5.3, interface DOES NOT NEED TO have default values.

Test script:
---------------
<?php
error_reporting(E_ALL | E_STRICT);

interface DefaultsInterface {
	public function foobar($a = false, $b = false, $c = false);
}
interface ParamsInterface {
	public function fubar($a, $b, $c);
}

class WorksFine implements DefaultsInterface {
	public function foobar($a = true, $b = false, $c = true) {}
}

class DiesOnFiveTwo implements ParamsInterface {
	public function fubar($a = true, $b = false, $c = true) {}
}

$a = new WorksFine();
$b = new DiesOnFiveTwo();
var_dump($a, $b);

Expected result:
----------------
I expect the documentation to mention the difference.

Actual result:
--------------
5.3 result:

object(WorksFine)[1]

object(DiesOnFiveTwo)[2]

5.2 result:

Fatal error: Declaration of DiesOnFiveTwo::fubar() must be compatible with that of ParamsInterface::fubar() in /var/www/dev.piklio.com/httpdocs/faces.php on line 17
