Jaki jest najlepszy sposób na usunięcie akcentów, np.Usunąć akcenty bez używania iconv
ÈâuÑ”staje się "Eaun"
Bez wykorzystaniem iconv

To nie jest kompletne. Nie zastępuje akcentów, gdy są w formie rozłożonej. – Artefacto
+0
Co to jest forma rozłożona? –
+1
@ Mark Zaktualizowałem swoją odpowiedź. Rozłożona forma "ÈâuÑ foo bar 88." to "ÈâuÑ foo bar 88.". Zależy od czcionki, ale powinny wyglądać tak samo. Oto przykład niepowodzenia twojej funkcji: http://codepad.viper-7.com/FAvL9I – Artefacto
18
O wiele prostszy:
$text = "ÈâuÑ foo bar 88.";
var_dump(preg_replace('/\p{M}/u', '',
Normalizer::normalize($text, Normalizer::FORM_D)));
daje:
string(16) "EauN foo bar 88."
Chodzi o to, aby rozłożyć znaki w postaci gdzie są one faktycznie dwie jednostki kodu Unicode, z indywidualnym jeden dla akcenty. Następnie usuwasz te akcenty.
\p{M}means "postać przeznaczona do łączenia z inną postacią (np. Akcentami, umlautami, załączonymi ramkami itp.)".
Należy pamiętać, że nie jest to ostateczne rozwiązanie. Może to wystarczyć dla tekstu wejściowego, ale wiele znaków, takich jak ø, nie ulega rozkładowi, więc ta metoda się nie powiedzie.
+0
Ale jego dostępność jest następująca: (PHP 5> = 5.3.0, PECL intl> = 1.0.0) – shamittomar
+0
Tak, mój pakiet nie ma klasy Normalizer ... –
+0
Biblioteka intl została dołączona do PHP 5.3. – Artefacto
-1
Albo spróbować tej funkcji (z str_replace i wyczerpującej tabeli akcentami): http://idilix.net/php-strip-accents.php
+5
To nie jest wyczerpujące: jest śmiesznie i żenująco naiwni! Po pierwsze, istnieje tylko 756 liter łacińskich z "akcentami". Dodaj kolejny tysiąc dla liter niełacińskich. Po drugie, nie używa żadnego rodzaju rozkładu, więc jest zepsute finansowo. Po trzecie, istnieje 237 łacińskich liter, które nie mają ** MIĘDZY dekompozycjami do naprawienia, lub około dwukrotnie, jeśli policzymy niełacińskie. Jest na to właściwy sposób, ale jest to takie złe, że nie powiem ci, jak. Naucz się korzystać z Unicode, a nie niszcz go. – tchrist

Napisałem to w php. Mam nadzieję, że to pomoże komuś. Unika mi konieczności używania iconv.
