Процедурный стиль

transliterator_transliterate ( mixed $transliterator , string $subject [, int $start [, int $end ]] )

Transforms a string or part thereof using an ICU transliterator.

Список параметров


In the procedural version, either a Transliterator or a string from which a Transliterator can be built.


The string to be transformed.


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.


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.

Возвращаемые значения

The transfomed string on success, или FALSE в случае возникновения ошибки.


Пример #1 Converting escaped UTF-16 code units

transliterator_transliterate("Hex-Any/Java"$s), "\n";

//now the reverse operation with a supplementary character
$supplChar html_entity_decode('&#x1D11E;');
mb_strlen($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";

You can create slugs easily with:

function slugify($string) {
$string transliterator_transliterate("Any-Latin; NFD; [:Nonspacing Mark:] Remove; NFC; [:Punctuation:] Remove; Lower();"$string);
$string preg_replace('/[-\s]+/''-'$string);

slugify("Я люблю PHP!");

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):
(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.

Sorry, for posting it again, but I found a bug in my code:

If you have a character, like the cyrillic ь (a soft-sign - no sound), the "Any-Latin" would translate it to a prime-character, and the "Latin-ASCII" doesn't touch prime-characters. Therefore I added an option to remove all characters, that are higher than \u0100.

Here's my new code, including an example:

var_dump(transliterator_transliterate('Any-Latin; Latin-ASCII; [\u0100-\u7fff] remove',
    "A æ Übérmensch på høyeste nivå! И я люблю PHP! есть. fi"));
// string(50) "A ae Ubermensch pa hoyeste niva! I a lublu PHP! est. fi"

Another approach, I found quite helpful (if you by no way want to remove characters ...), try to use iconv() in addition. This surely will just return ASCII characters.


Also an example here:

var_dump(iconv("UTF-8", "ASCII//TRANSLIT//IGNORE", transliterator_transliterate('Any-Latin; Latin-ASCII',
    "A æ Übérmensch på høyeste nivå! И я люблю PHP! есть. fi"));
// string(50) "A ae Ubermensch pa hoyeste niva! I a lublu PHP! est'. fi"

There are some possibly undesirable conversions with ASCII//TRANSLIT//IGNORE or your users may require some custom stuff.

You might want to run a substitution up front for certain things, such as when you want 3 letter ISO codes to replace currency symbols. £ transliterates to "lb", for example, which is incorrect since it's a currency symbol, not a weight symbol (#). 

ASCII//TRANSLIT//IGNORE does a great job within the realm of possibility :-)

When it doesn't do something you want it to, you can set up a CSV with one replacement per line and run a function like:

    function stripByMap($inputString, $mapFile)
        $csv = file($mapFile);
        foreach($csv as $line)
            $arrLine = explode(',', trim($line));
            $inputString = str_replace($arrLine[0],$arrLine[1],$inputString);
        return $inputString;

or you can write some regexes. Transliterating using ASCII//TRANSLIT//IGNORE  works so well that your map probably won't be very long...
