transliterator_transliterate

(PHP 5 >= 5.4.0, PHP 7, 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 string Transliterator::transliterate ( string $subject [, int $start [, int $end ]] )

手続き型

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

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。

subject

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。

返り値

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...
