PHP UTF-8

<?php
public function singleRepresentation($str)
{
// dynamically requiring file of phputf8 library,
// as it is only required if this function is
// called
require_once 'utf8/utils/ascii.php';
return utf8_decode(utf8_accents_to_ascii($str));
}
?>
Problem is!

utf8/utils/ascii.php contains global variables
$UTF8_LOWER_ACCENTS & $UTF8_UPPER_ACCENTS which
when required by a function become local to that
function!

Resulting in problems for utf8_accents_to_ascii()
that can no longer locate the variables it needs.

The solution is to change:
<?php
$UTF8_LOWER_ACCENTS = array(...);
?>
to
<?php
$GLOBALS['UTF8_LOWER_ACCENTS'] = array(...);
?>
