Modify vBulletin php source code

[idisforum]

I have some multi-byte character problems with php5

e.g) first multi-byte character is disappeared when uploading file. -> this is php5 basename() problem

so I go to /core/includes/class_upload.php

and write

function getbasename($path)
{
code for correct basename with multi-byte
..
..
}

and change

$this->upload['filename'] = basename($upload);
to
$this->upload['filename'] = getbasename($upload);

but when I watching packet, there is no change..

so I test
$this->upload['filename'] = basename('/var/www/test.txt');

but result is equal to original source code. ($this->upload['filename'] = basename($upload))

I have to do something for working vbulletin with modified source code
or
uploading attachment source is not in the /core/includes/class_upload.php?

p.s
I want to also modify download attachment source.
this source is in the /core/includes/functions_file.php?

You need to set the locale first before calling basename(). Try this PHP fiddle:

I use Japanese characters as sample.
