参数
-
transliterator -
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.
返回值
The transfomed string on success, 或者在失败时返回 FALSE .
范例
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" ;
?> 以上例程的输出类似于：
お早うございます 1 \uD834\uDD1E ?

Sorry, for posting it again, but I found a bug in my code:
If you have a character, like the cyrillic ?? (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 ? ?b??rmensch p? h?yeste niv?! ?? ?? ?????? PHP! ?????. ?"));
// 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 ? ?b??rmensch p? h?yeste niv?! ?? ?? ?????? PHP! ?????. ?"));
// string(50) "A ae Ubermensch pa hoyeste niva! I a lublu PHP! est'. fi"

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. ?)
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 ? ?b??rmensch p? h?yeste niv?! ?? ?? ?????? PHP! ?"));
// 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.

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("?? ?????? PHP!");
?>

OOP version :
<?php
$str = '??????????????????????????????????????
?????????????????????????';
$rule = 'NFD; [:Nonspacing Mark:] Remove; NFC';
$myTrans = Transliterator::create($rule);
echo $myTrans->transliterate($str);
//aaaaaceeeeiiiinooooouuuuyy
//AAAAACEEEEIIIINOOOOOUUUUY
?>
