    Transliterator::transliterate

    transliterator_transliterate

    (PHP 5 >= 5.4.0, PHP 7, PHP 8, PECL intl >= 2.0.0)

    Transliterator::transliterate -- transliterator_transliterate — 文字列を音訳する

    説明

    オブジェクト指向型

    public Transliterator::transliterate(string $string, int $start = 0, int $end = -1): string|false

    手続き型

    transliterator_transliterate(
        Transliterator|string $transliterator,
        string $string,
        int $start = 0,
        int $end = -1
    ): string|false

    文字列あるいはその一部をICU の音訳器を使って変換します。

    パラメータ

    transliterator

    手続き型の場合に、Transliterator あるいは Transliterator を作成できる文字列を指定します。

    string

    変換する文字列。

    start

    文字列の変換の開始位置を表すインデックス (UTF-16 コード単位) を指定します。指定した位置も、変換範囲に含まれます。 インデックスは 0 から始まります。この位置より前にあるテキストは、そのまま残ります。

    end

    文字列の変換の終了位置を表すインデックス (UTF-16 コード単位) を指定します。指定した位置は、変換範囲に含まれません。 インデックスは 0 から始まります。この位置も含めてそれ以降にあるテキストは、そのまま残ります。

    戻り値

    成功した場合に変換後の文字列を返します。 失敗した場合に false を返します。

    例

    例1 エスケープされた UTF-16 コード単位の変換

    <?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
    $supplChar = html_entity_decode('&#x1D11E;');
    echo     mb_strlen($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";
    ?>

    上の例の出力は、 たとえば以下のようになります。

    お早うございます

    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.

    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.

    See: http://stackoverflow.com/a/3542748/517914

    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"

    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!");
    ?>

    OOP version :

    <?php
    $str     = 'àáâãäçèéêëìíîïñòóôõöùúûüýÿ
    ÀÁÂÃÄÇÈÉÊËÌÍÎÏÑÒÓÔÕÖÙÚÛÜÝ'    ;
    $rule = 'NFD; [:Nonspacing Mark:] Remove; NFC';

    $myTrans = Transliterator::create($rule);
    echo     $myTrans->transliterate($str);

    //aaaaaceeeeiiiinooooouuuuyy
    //AAAAACEEEEIIIINOOOOOUUUUY
    ?>

    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...
