How do I remove accents from characters in a PHP string?

Solution:1

UTF-8 friendly version of the simple function posted above by Gino:

function stripAccents($str) {
    return strtr(utf8_decode($str), utf8_decode('àáâãäçèéêëìíîïñòóôõöùúûüýÿÀÁÂÃÄÇÈÉÊËÌÍÎÏÑÒÓÔÕÖÙÚÛÜÝ'), 'aaaaaceeeeiiiinooooouuuuyyAAAAACEEEEIIIINOOOOOUUUUY');
}

Had to come to this because my php document was UTF-8 encoded.

Hope it helps.

Solution:2

When using iconv, the parameter locale must be set:

function test_enc($text = 'ěščřžýáíé ĚŠČŘŽÝÁÍÉ fóø bår FÓØ BÅR æ')
{
    echo '<tt>';
    echo iconv('utf8', 'ascii//TRANSLIT', $text);
    echo '</tt><br/>';
} 

test_enc();
setlocale(LC_ALL, 'cs_CZ.utf8');
test_enc();
setlocale(LC_ALL, 'en_US.utf8');
test_enc();

Yields into:

????????? ????????? f?? b?r F?? B?R ae
escrzyaie ESCRZYAIE fo? bar FO? BAR ae
escrzyaie ESCRZYAIE fo? bar FO? BAR ae

Another locales then cs_CZ and en_US I haven’t installed and I can’t test it.

In C# I see solution using translation to unicode normalized form – accents are splitted out and then filtered via nonspacing unicode category.
