不确定它适用于每一种情况，但我从Laravel Str类中采用了slug方法，并添加了iconv('utf-8'， 'us-ascii//TRANSLIT'， $title)的东西来处理口音，而不需要使用voku/便携式ascii，这似乎对我的用例工作得很好:

    public static function slug($title, $separator = '-')
    {
        $title = iconv('utf-8', 'us-ascii//TRANSLIT', $title);
        $flip = $separator === '-' ? '_' : '-';
        $title = preg_replace('!['.preg_quote($flip).']+!u', $separator, $title);
        // Replace @ with the word 'at'
        $title = str_replace('@', $separator.'at'.$separator, $title);
        // Remove all characters that are not the separator, letters, numbers, or whitespace.
        $title = preg_replace('![^'.preg_quote($separator).'\pL\pN\s]+!u', '', mb_strtolower($title, 'UTF-8'));
        // Replace all separator characters and whitespace by a single separator
        $title = preg_replace('!['.preg_quote($separator).'\s]+!u', $separator, $title);

        return trim($title, $separator);
    }

我不知道该用哪一个，所以我在phptester.net上做了一个快速的长凳

我认为最优雅的方法是使用Behat\Transliterator\Transliterator。

我需要通过你的类扩展这个类，因为它是一个抽象，一些像这样:

<?php
use Behat\Transliterator\Transliterator;

class Urlizer extends Transliterator
{
}

然后，使用它:

$text = "Master Ápiu";
$urlizer = new Urlizer();
$slug = $urlizer->transliterate($slug, "-");
echo $slug; // master-apiu

当然你也应该把这些东西放到你的作曲器里。

composer require behat/transliterator

注意:我已经从wordpress和它的工作!!

像这样使用它:

    $string_length = strlen( $utf8_string );
    for ($i = 0; $i < $string_length; $i++ ) {

        $value = ord( $utf8_string[ $i ] );

        if ( $value < 128 ) {
            if ( $length && ( $unicode_length >= $length ) )
                break;

            $values[] = $value;

            if ( $length && ( $unicode_length + ($num_octets * 3) ) > $length )
                break;
            if ( count( $values ) == $num_octets ) {
                if ($num_octets == 3) {
                    $unicode .= '%' . dechex($values[0]) . '%' . dechex($values[1]) . '%' . dechex($values[2]);
                    $unicode_length += 9;
