Удалить акценты без использования iconv

Question

Какой лучший способ убрать акценты, например.

becomesâuÑ "становится" Eaun "

Без с использованием iconv

Answer 1

Намного проще:

$text = "ÈâuÑ foo bar 88.";
var_dump(preg_replace('/\p{M}/u', '',
    Normalizer::normalize($text, Normalizer::FORM_D)));

дает:

string(16) "EauN foo bar 88."

Идея состоит в том, чтобы разложить символы в форму, в которой они фактически являются двумя единицами кода Unicode, с отдельной для акцентов. Затем вы удаляете эти акценты.

\p{M} означает «символ, предназначенный для объединения с другим символом (например, ударения, умлауты, заключенные в рамки и т. Д.)».

Обратите внимание, что это не окончательное решение. Этого может быть достаточно для ввода текста, который у вас есть, но многие символы, такие как ø, не разлагаются, поэтому этот метод завершится неудачей.

Answer 2

Полный рабочий код. Я знаю, что это длинный, но верный способ, используемый Wordpress.

<?php

function seems_utf8($str) 
{
    $length = strlen($str);
    for ($i=0; $i < $length; $i++) {
        $c = ord($str[$i]);
        if ($c < 0x80) $n = 0; # 0bbbbbbb
        elseif (($c & 0xE0) == 0xC0) $n=1; # 110bbbbb
        elseif (($c & 0xF0) == 0xE0) $n=2; # 1110bbbb
        elseif (($c & 0xF8) == 0xF0) $n=3; # 11110bbb
        elseif (($c & 0xFC) == 0xF8) $n=4; # 111110bb
        elseif (($c & 0xFE) == 0xFC) $n=5; # 1111110b
        else return false; # Does not match any model
        for ($j=0; $j<$n; $j++) { # n bytes matching 10bbbbbb follow ?
            if ((++$i == $length) || ((ord($str[$i]) & 0xC0) != 0x80))
                return false;
        }
    }
    return true;
}
