Topic awaiting preservation: banging head -anyone know why this does not work? (Page 1 of 1)

$imgregexp = '/(src=")([^"]+)(")/';
$page = {... some html document...}
$shu = 'sha';
function acallback($matches)
{
global $shu;
print('a.'. $GLOBALS['shu']. '<br />');
print('b.'. $shu. '<Br />');
return 'sha';
}

preg_replace_callback($imgregexp,'acallback',$page);

ok, that's the code.
Now, it should print something like 'a.sha<Br />' and 'b.sha<br />' (many times, since the expression is quite a few times in the document).
What it does is print 'a.<Br />' and 'b.<Br />'...

so does anybode know why in the world this is happening?
(of course the above code is a purified example. the real code was to add it to a global array... but that didn't work either.)

thank you,

only problem is that I'll need the assignment outside the function,
and darn it, this should be working.

(edit: setting it inside the function does work. but then, I'm not able to access the new value outside the function. I have a sneeking suspicion...


OK: here's the solution. acallback is defined within another function. So I have to declare my variable global in that function as well. Thank you InI.

and they show, once again, that the whole concept of php having functions inside functions is flawed. (I don't even want to have this variable global. I just want to access the parents functions scope.)

Should teach me not to write functions where I can't see the function xxx at the top, because the code's longer than a page.
