File Upload Class: Change file name

[eluser]Lionel H[/eluser]
Hello,

I use a solution that changes the filename before the upload, but as I'm not a PHP master, I'm not sure it's the perfect solution (but it works) :

Code:

$value = $_FILES['userfile']['name'];

$value = utf8_decode($value);

$value = strtr($value, utf8_decode('ÀÁÂÃÄÅÇÈÉÊËÌÍÎÏÒÓÔÕÖÙÚÛÜÝÑñàáâãäåçèéêëìíîïðòóôõöùúûüýÿ'), 'AAAAAACEEEEIIIIOOOOOUUUUYNnaaaaaaceeeeiiiioooooouuuuyy');

$value = preg_replace('/( +)/i', '_', $value);

$value = strtolower($value);

$_FILES['userfile']['name'] = $value;
