Re: Is this a php bug?

And when i use function declaration replace with interface and class,
it works fine. See below:

[yarco@localhost test]$ cat test1.php
<?php

function test1()
{
test2();
}

?>
[yarco@localhost test]$ cat test2.php
<?php
function test2()
{
}
?>
[yarco@localhost test]$ cat test3.php
<?php
require_once dirname(__FILE__).'/test1.php';
require_once dirname(__FILE__).'/test2.php';
?>
[yarco@localhost test]$ php test3.php
[yarco@localhost test]$

If it works as you said, this can not happen.

Think about what's happening here. You include test2.php first. That
declares class B which implements interface C. But interface C is
defined in test1.php which hasn't been included yet, so the interface
is undefined.
