You can create slugs easily with:
<?php
function slugify($string) {
$string = transliterator_transliterate("Any-Latin; NFD; [:Nonspacing Mark:] Remove; NFC; [:Punctuation:] Remove; Lower();", $string);
$string = preg_replace('/[-\s]+/', '-', $string);
return trim($string, '-');
}
echo slugify("Я люблю PHP!");
?>

In the procedural version, either a Transliterator or a string from which a Transliterator can be built.
-
subject -
The string to be transformed.
-
start -
The start index (in UTF-16 code units) from which the string will start to be transformed, inclusive. Indexing starts at 0. The text before will be left as is.
-
end -
The end index (in UTF-16 code units) until which the string will be transformed, exclusive. Indexing starts at 0. The text after will be left as is.
Valori restituiti
The transfomed string on success, o FALSE in caso di fallimento.
Esempi
Example #1 Converting escaped UTF-16 code units
<?php
$s = "\u304A\u65E9\u3046\u3054\u3056\u3044\u307E\u3059";
echo transliterator_transliterate("Hex-Any/Java", $s), "\n";
//now the reverse operation with a supplementary character
$supplChar = html_entity_decode('𝄞');
echo mb_strlen($supplChar, "UTF-8"), "\n";
$encSupplChar = transliterator_transliterate("Any-Hex/Java", $supplChar);
//echoes two encoded UTF-16 code units
echo $encSupplChar, "\n";
//and back
echo transliterator_transliterate("Hex-Any/Java", $encSupplChar), "\n";
?>

I pretty much like the idea of hdogan, but there's at least one group of characters he's missing: ligature characters.
They're at least used in Norwegian and I read something about French, too ... Some are just used for styling (f.e. fi)
Here's an example that supports all characters (should at least, according to the documentation):
<?php
var_dump(transliterator_transliterate('Any-Latin; Latin-ASCII; Lower()', "A æ Übérmensch på høyeste nivå! И я люблю PHP! fi"));
// string(41) "a ae ubermensch pa hoyeste niva! i a lublu php! fi"
?>
In this example any character will firstly be converted to a latin character. If that's finished, replace all latin characters by their ASCII replacement.
OOP version :
<?php
$str = 'àáâãäçèéêëìíîïñòóôõöùúûüýÿ
ÀÁÂÃÄÇÈÉÊËÌÍÎÏÑÒÓÔÕÖÙÚÛÜÝ';
$rule = 'NFD; [:Nonspacing Mark:] Remove; NFC';
$myTrans = Transliterator::create($rule);
echo $myTrans->transliterate($str);
//aaaaaceeeeiiiinooooouuuuyy
//AAAAACEEEEIIIINOOOOOUUUUY
?>
