Re: Is this a php bug?

Hey friend, i don't agree with you.
We may always treat include/require as they include something into the
original file.
So if test1.php:
<?php
$a = 1;
?>
test2.php is:
<?php
include 'test1.php';
print $a;
?>
We may treat test2.php as:
<?php
$a = 1;
print $a;
?>

So let's look at test1/test2/test3. If we treat test3 as:
[yarco@localhost test]$ cat test3.php
<?php

class B implements C
{

}

interface C
{

}

class A extends B
{

}

?>[yarco@localhost test]$ php test3.php
[yarco@localhost test]$

It certainly could work fine. So i don't think it should give an error
when i do that.
And __autoload also does't give me any help.

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.

Read about __autoload:

<http://www.php.net/autoload>

You can disagree all you want but that isn't how it works. Try this
one:

bar.php:
<?php
function bar() {
echo 'This is bar.';
}
?>

foo.php:
<?php
bar();
include('bar.php');
?>

And it throws an error because it doesn't know what bar() is. Just
because it's /logically/ the same as dropping the code in there
doesn't mean that's how it's actually evaluated.
