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

在Laravel 8中是:

Str::slug('Hola como te va', '-');

// hola-como-te-va

如果你安装了intl扩展，你可以使用Transliterator::transliterate函数轻松创建一个slug。

$string = 'Namnet på bildtävlingen';

$rules = <<<'RULES'
    :: Any-Latin;
    :: NFD;
    :: [:Nonspacing Mark:] Remove;
    :: NFC;
    :: [^-[:^Punctuation:]] Remove;
    :: Lower();
    [:^L:] { [-] > ;
    [-] } [:^L:] > ;
    [-[:Separator:]]+ > '-';
RULES;

$slug = \Transliterator::createFromRules($rules)
    ->transliterate( $string );

echo $slug; // namnet-pa-bildtavlingen

请注意，这种解决方案适用于任何字母表，并且非常灵活。

我正在使用这个函数，它工作得很好:

function slugify($string) {
  return strtolower(trim(preg_replace('~[^0-9a-z]+~i', '-', html_entity_decode(preg_replace('~&([a-z]{1,2})(?:acute|cedil|circ|grave|lig|orn|ring|slash|th|tilde|uml);~i', '$1', htmlentities($string, ENT_QUOTES, 'UTF-8')), ENT_QUOTES, 'UTF-8')), '-'));
}
