在 Laravel 中使用阿拉伯字符作为 Slug

Question

我正在使用这个包Github：eluquent-sluggable-persian使用阿拉伯语来表示 slug，他们使用正则表达式来表示包配置文件，我不太擅长它，我遇到的错误是

sluggable.php 第 106 行中的 ErrorException：
preg_replace()：编译失败：在偏移量 0 处无需重复

sluggable.php 是我应该用原始配置文件替换的配置文件，我需要知道如何解决这个问题。

有错误的代码

'method' => function($string, $separator = '-')
{
    $_transliteration = array(
        '/ä|æ|?/' => 'ae',
        '/ö|œ/' => 'oe',

    $map = $_transliteration + $merge;
    unset($_transliteration);
    return preg_replace(array_keys($map), array_values($map), $string);

我已经解决了这个问题，已经用另一种方法替换了这个方法

'method' => function ($string, $separator = '-') {
    if (is_null($string)) {
        return "";
    }

    // Remove spaces from the beginning and from the end of the string
    $string = trim($string);

    // Lower case everything
    // using mb_strtolower() function is important for non-Latin UTF-8 string | more info: https://www.php.net/manual/en/function.mb-strtolower.php
    $string = mb_strtolower($string, "UTF-8");;

    // Make alphanumeric (removes all other characters)
    // this makes the string safe especially when used as a part of a URL
    // this keeps latin characters and arabic charactrs as well
    $string = preg_replace("/[^a-z0-9_\s\-????????????????????????????????????]#u/", "", $string);

    // Remove multiple dashes or whitespaces
    $string = preg_replace("/[\s-]+/", " ", $string);

    // Convert whitespaces and underscore to the given separator
    $string = preg_replace("/[\s_]/", $separator, $string);

    return $string;
},

它现在工作谢谢^^
