How can I sort an array of UTF-8 strings in PHP?

Question

need help with sorting words by utf-8. For example, we have 5 cities from Belgium.

$array = array(\'Borgloon\',\'Thuin\',\'Lennik\',\'Éghezée\',\'Aubel\');

As for strcoll I guess it was a nice idea, but doesn't seem to work:

A while back I wrote a UTF-8 to ASCII tool that would convert "älph#bla" to "aelph-bla". You could use this to "normalize" your input to make it sortable. It's basically a replacement similar to what @Nick said.

You should use a separate array for sorting, as calling urlify() in a usort() callback would be wasting a lot of resources. try

 $v) {
    // "normalize" utf8 to ascii
    $_array[$k] = urlify($v);
}
// sort the ASCII stuff (while preserving indexes)
asort($_array);
foreach ($_array as $key => &$v) {
    // copy the original value of the ASCIIfied element
    $v = $array[$k];
}
var_dump($_array);

If you have PHP5.3 or the intl PECL compiled, try @Thai's solution, seems sweet!
