PHP: Transliterator::create - Manual

Warning

This function is currently not documented; only its argument list is available.

// Translit each and every char to ASCII

$string = 'Москва́';
$string = Transliterator::create('Any-Latin; Latin-ASCII')->transliterate($string);

print $string;

// the result is "Moskva"

A good example of create for non latin languages is Turkish.

There both upper case I character and lowercase ı character which makes other strtolower kind of functions useless.

$text = "Iğdır";

echo Transliterator::create("tr-Lower")->transliterate($text);

will return the correct result ığdır, not iğdır .

echo Transliterator::create('tr-upper')->transliterate("ığdır") . PHP_EOL;
echo Transliterator::create('tr-lower')->transliterate("IĞDIR");

result => IĞDIR ığdır
