我想阻止或删除网站中所有不需要的字符

像ᾄҭᾄ 或єℓℓσ ĤĔĹĹŐ 等等

我现在的代码是

class badWordsC
{
    public function check($text)
    {
        $badwords    = 'com|net|org|info|.name|.biz|.me|.tv|.tel|.mobi|.asia|.uk|.eu|.us|.in|.tk|.cc|.ws|.bz|.mn|.co|.tw|.vn|.es|.pw|.club|.ca|.cn|.email|.photography|.photos|.tips|.solutions|.center|.gallery|.kitchen|.land|.technology|.today|.academy|.computer|.shoes|.careers|.domains|.coffee|.link|.guru|.estate|.company|.bike|.clothing|.holdings|.plumbing|.singles|.ventures|.camera|.equipment|.graphics|.lighting|.construction|.contractors|.directory|.diamonds|.enterprises|.voyage|.recipes|.gift|.site|.ly|.gq|.cf|.ga|.ml|.tk|in|rb2';
        $badwords   .= 'type|ingoogle';
        $badwords    = explode('|', $badwords);

        $goodwords   = 'youtube.com|prntscr.com|az545221.vo.msecnd.net';
        $goodwords  .= 'wink|crying|fingerscrossed|blushing|wondering|inlove|evilgrin|yawning|puking|in';
        $goodwords   = explode('|', $goodwords);


        $text        = str_replace($goodwords, '', $text);
        $text        = trim(preg_replace('/\s\s+/', '', $text));
        $text        = preg_replace('/\P{L}+/u', '', $text);




        foreach ($badwords as $word)
        {
            if (strpos($text, $word) !== false || strpos($text, strtoupper($word)) !== false)
            {
                return false;
            }
        }

        $text = preg_replace("/[a-zA-Z0-9]/", '', $text);
        $text = preg_replace(array('/)/','/(/','/;/','/-/','/+/','/لأ/','/لإ/','/لا/','/إ/','/أ/', '/ا/', '/ض/', '/ص/', '/ث/', '/ق/', '/ف/', '/غ/', '/ع/', '/ه/', '/خ/', '/ح/', '/ج/', '/د/', '/ش/', '/س/', '/ي/', '/ب/', '/ل/', '/ت/', '/ن/', '/م/', '/ك/', '/ط/', '/ئ/', '/ء/', '/ؤ/', '/ر/', '/ى/', '/ة/', '/و/', '/ز/', '/ظ/', '/ذ/', '/ـ/'), '', $text);



        if($text != '')
        {
            return false;
        }

        return true;
    }
}
它可以工作,但不能阻塞或删除像ĔŐ这样的字符


有什么想法吗?

您需要使用的
u
修饰符您还需要扩展字符类以包含非ascii字符

我会使用:

/[[:alnum:]]/u
正则表达式演示:

这是一个posix括号,您可以在这里看到更多,www.regular-expressions.info/posix括号.html


另外,在第二个表达式中,
+
需要转义(或者放入字符类中,有些符号放入字符不会修复
-
]
^
),因为这是一个量词。有一个PHP函数将转义特殊字符。

您可以尝试以下操作:
/(?:(?![a-zäöü])\p{L})+/iu
@bobble bubble/(?:(?![a-zäüü223;])\p{L})+/iu notworking@chris85我发行的$text=preg_replace(“/[a-zA-Z0-9]/”,“,”,$text)@chris85正在工作,我想如果我删除了preg_replace数组,我已经找到了这个$text=preg_replace(数组('/)/'),'/目前,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,34,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,“”,$text);所有代码都可以工作,但我需要那个数组来创建好的单词
